加载并运行WPF DLL到另一个WPF exe [英] Load and Run WPF DLL into Another WPF exe
问题描述
WPF_APP1 - >在排除App.xaml之后，我创建了这个wpf项目的dll
WPF_APP2 - >正常的WPF exe。需要运行上述WPF_APP1 dll并使用反射打开WPF_APP1 MainWindow窗体。
为什么我在说反思是 -
WPF_APP2 首先得到最新的 WPF_APP1.dll ，然后打开，所以不能添加dll的引用。只能使用反思。
当我在cmd项目中使用上述dll时，它还好。它打开CMD窗口，然后启动 WPF_APP1 MainWindow 作为窗口窗体。
但是现在我需要打开这个窗体，而不是cmd， WPF_APP2 。
请帮助我。
CMD项目使用以下代码打开 WPF_APP1 MainWindow。
static void Main（string [] args）
{
Thread t = new Thread（ThreadProc）;
t.SetApartmentState（ApartmentState.STA）;
t.IsBackground = true;
t.Start（）;
Console.ReadLine（）;
}
private static void ThreadProc（）
{
string loc = new FileInfo（Assembly.GetExecutingAssembly（）。Location）.DirectoryName
+\\AutoUpdateTesting.dll;
装配dll = Assembly.LoadFile（loc）;
foreach（type type in dll.GetExportedTypes（））
{
if（type.Name.Equals（MainWindow））
{
动态n = null;
n = Activator.CreateInstance（type）;
n.InitializeComponent（）;
System.Windows.Application apprun = new System.Windows.Application（）;
apprun.Run（n）;
break;
}
}
}
我可以不使用行 -
System.Windows.Application apprun = new System.Windows.Application（）;
在WPF_APP2中，因为AppDomain（在google上找到这个原因）。尝试其他选择，但没有运气。
请看看并分享您的知识。 ：）
等待您的意见和回复。
谢谢
从表单应用程序加载WPF窗口：
静态类程序
{
[STAThread]
static void Main（）
{
Application.EnableVisualStyles（）;
Application.SetCompatibleTextRenderingDefault（false）;
ThreadProc（）;
Application.Run（）; // 继续跑！
}
private static void ThreadProc（）
{
if（System.Windows.Application.Current == null）
new System.Windows。应用（）;
尝试
{
string assemblyName = string.Format（{0} \\\AutoUpdateTesting.dll），新的FileInfo（Assembly.GetExecutingAssembly（））位置）.DirectoryName）
System.Windows.Application.Current.Dispatcher.BeginInvoke（DispatcherPriority.Normal，new Action（（）=>
{
Window wnd = LoadAssembly（assemblyName，OtherWindow）;
wnd.Show（）;
}））;
}
catch（Exception ex）
{
System.Diagnostics.Trace.WriteLine（string.Format（Failed to load window from {0} - {1}， OtherWindow，ex.Message））;
throw new Exception（String.Format（Failed to load window from {0} - {1}，OtherWindow，ex.Message），ex）;
}
}
private static Window LoadAssembly（String assemblyName，String typeName）
{
try
{
Assembly assemblyInstance = Assembly.LoadFrom（assemblyName）;
foreach（在assemblyInstance.GetTypes（）中键入t）其中（t => String.Equals（t.Name，typeName，StringComparison.OrdinalIgnoreCase））
{
var wnd = assemblyInstance .CreateInstance（t.FullName）为Window;
return wnd;
}
抛出新异常（无法加载外部窗口）;
}
catch（Exception ex）
{
System.Diagnostics.Trace.WriteLine（string.Format（Failed to load window from {0} {1}，assemblyName ，ex.Message））;
throw new Exception（string.Format（Failed to load external window {0}，assemblyName），ex）;
}
}
}
！请记住，您需要添加对基础WPF程序集（PresentationCore，WindowBase +++）的引用
WPF加载外部窗口这里你有wpf到wpf）
public partial class App：Application
{
App ）
{
启动+ = App_Startup;
}
void App_Startup（object sender，StartupEventArgs e）
{
try
{
string assemblyName = string.Format（{ 0} \\AutoUpdateTesting.dll，新的FileInfo（Assembly.GetExecutingAssembly（）。Location）.DirectoryName）;
窗口wnd = LoadAssembly（assemblyName，OtherWindow）;
wnd.Show（）;
}
catch（Exception ex）
{
System.Diagnostics.Trace.WriteLine（string.Format（Failed to load window from {0} - {1}， OtherWindow，ex.Message））;
throw new Exception（String.Format（Failed to load window from {0} - {1}，OtherWindow，ex.Message），ex）;
}
}
私有Window LoadAssembly（String assemblyName，String typeName）
{
try
{
assembly assemblyInstance = Assembly.LoadFrom（assemblyName）;
foreach（在assemblyInstance.GetTypes（）中键入t）其中（t => String.Equals（t.Name，typeName，StringComparison.OrdinalIgnoreCase））
{
var wnd = assemblyInstance .CreateInstance（t.FullName）为Window;
return wnd;
}
抛出新异常（无法加载外部窗口）;
}
catch（Exception ex）
{
System.Diagnostics.Trace.WriteLine（string.Format（Failed to load window from {0} {1}，assemblyName ，ex.Message））;
throw new Exception（string.Format（Failed to load external window {0}，assemblyName），ex）;
}
}
}
希望它有帮助！ p>

My main issue is as I stated in title.
WPF_APP1 --> I created dll of this wpf project after excluding App.xaml
WPF_APP2 --> Normal WPF exe. which needs to run the above WPF_APP1 dll and open the WPF_APP1 MainWindow form using reflection.
Why I am saying for reflection is - WPF_APP2 first get the latest WPF_APP1.dll then open so can not add the reference of dll. have to use the Reflection only.
When I use the above dll in cmd project its okay. it open the CMD window then launch the WPF_APP1 MainWindow as Window form.
But Now I need to open this window form not in cmd, in WPF_APP2.
Please help me out.
CMD project use the below code to open the WPF_APP1 MainWindow.
static void Main(string[] args)
{
Thread t = new Thread(ThreadProc);
t.SetApartmentState(ApartmentState.STA);
t.IsBackground = true;
t.Start();
Console.ReadLine();
}
private static void ThreadProc()
{
string loc = new FileInfo(Assembly.GetExecutingAssembly().Location).DirectoryName
+ "\\AutoUpdateTesting.dll";
Assembly dll = Assembly.LoadFile(loc);
foreach (Type type in dll.GetExportedTypes())
{
if (type.Name.Equals("MainWindow"))
{
dynamic n = null;
n = Activator.CreateInstance(type);
n.InitializeComponent();
System.Windows.Application apprun = new System.Windows.Application();
apprun.Run(n);
break;
}
}
}
I can not use line -
System.Windows.Application apprun = new System.Windows.Application();
In WPF_APP2 because of AppDomain(found this reason on google). Try other alternative but no luck.
Please have a look and share your knowledge. :)
waiting for your comments and reply.
Thanks
Load WPF window from forms application:
static class Program
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
ThreadProc();
Application.Run(); // Keep on running!
}
private static void ThreadProc()
{
if (System.Windows.Application.Current == null)
new System.Windows.Application();
try
{
string assemblyName = string.Format("{0}\\AutoUpdateTesting.dll", new FileInfo(Assembly.GetExecutingAssembly().Location).DirectoryName);
System.Windows.Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
{
Window wnd = LoadAssembly(assemblyName, "OtherWindow");
wnd.Show();
}));
}
catch (Exception ex)
{
System.Diagnostics.Trace.WriteLine(string.Format("Failed to load window from{0} - {1}", "OtherWindow", ex.Message));
throw new Exception(String.Format("Failed to load window from{0} - {1}", "OtherWindow", ex.Message), ex);
}
}
private static Window LoadAssembly(String assemblyName, String typeName)
{
try
{
Assembly assemblyInstance = Assembly.LoadFrom(assemblyName);
foreach (Type t in assemblyInstance.GetTypes().Where(t => String.Equals(t.Name, typeName, StringComparison.OrdinalIgnoreCase)))
{
var wnd = assemblyInstance.CreateInstance(t.FullName) as Window;
return wnd;
}
throw new Exception("Unable to load external window");
}
catch (Exception ex)
{
System.Diagnostics.Trace.WriteLine(string.Format("Failed to load window from{0}{1}", assemblyName, ex.Message));
throw new Exception(string.Format("Failed to load external window{0}", assemblyName), ex);
}
}
}
That does the trick for forms! Remember that you need to add references to the base WPF assemblies(PresentationCore, WindowBase+++)
WPF loading external window (Read your post wrong, so here you have wpf to wpf as well)
public partial class App : Application
{
App()
{
Startup += App_Startup;
}
void App_Startup(object sender, StartupEventArgs e)
{
try
{
string assemblyName = string.Format("{0}\\AutoUpdateTesting.dll", new FileInfo(Assembly.GetExecutingAssembly().Location).DirectoryName);
Window wnd = LoadAssembly(assemblyName, "OtherWindow");
wnd.Show();
}
catch (Exception ex)
{
System.Diagnostics.Trace.WriteLine(string.Format("Failed to load window from{0} - {1}", "OtherWindow", ex.Message));
throw new Exception(String.Format("Failed to load window from{0} - {1}", "OtherWindow", ex.Message), ex);
}
}
private Window LoadAssembly(String assemblyName, String typeName)
{
try
{
Assembly assemblyInstance = Assembly.LoadFrom(assemblyName);
foreach (Type t in assemblyInstance.GetTypes().Where(t => String.Equals(t.Name, typeName, StringComparison.OrdinalIgnoreCase)))
{
var wnd = assemblyInstance.CreateInstance(t.FullName) as Window;
return wnd;
}
throw new Exception("Unable to load external window");
}
catch (Exception ex)
{
System.Diagnostics.Trace.WriteLine(string.Format("Failed to load window from{0}{1}", assemblyName, ex.Message));
throw new Exception(string.Format("Failed to load external window{0}", assemblyName), ex);
}
}
}
Hope it helps!
