在不安装Visual Studio的情况下以编程方式即时创建csproj [英] Programmatically create a csproj on the fly without Visual Studio installed
问题描述
我正在尝试使用 MSBuild
命名空间以编程方式生成.csproj文件,但是缺少代码示例使此过程变得乏味且容易出错。
I am attempting to generate a .csproj file programatically using the MSBuild
namespace, but the lack of code samples is making this a tedious and error prone process.
到目前为止,我已经获得了以下代码,但是我不确定如何向项目中添加类,引用等。
So far, I have got the following code but I am not sure how to add classes, references and such to the project.
public void Build()
{
string projectFile = string.Format(@"{0}\{1}.csproj", Common.GetApplicationDataFolder(), _project.Target.AssemblyName);
Microsoft.Build.Evaluation.Project p = new Microsoft.Build.Evaluation.Project();
ProjectCollection pc = new ProjectCollection();
Dictionary<string, string> globalProperty = new Dictionary<string, string>();
globalProperty.Add("Configuration", "Debug");
globalProperty.Add("Platform", "x64");
BuildRequestData buildRequest = new BuildRequestData(projectFile, globalProperty, null, new string[] { "Build" }, null);
p.Save(projectFile);
BuildResult buildResult = BuildManager.DefaultBuildManager.Build(new BuildParameters(pc), buildRequest);
}
谢谢。
推荐答案
如果您真的想使用MSBuild API创建proj文件,则必须使用Microsoft.Build.Construction命名空间。您将需要的大多数类型都在Micrsoft.Build.dll程序集中。一个简短的示例,该示例创建具有一些属性和项目组的项目文件:
If you really want to create a proj file with MSBuild API you have to use the Microsoft.Build.Construction namespace. Most of the types you will need are in the Micrsoft.Build.dll assembly. A short sample that creates a project file with a few properties and item groups:
class Program
{
static void Main(string[] args)
{
var root = ProjectRootElement.Create();
var group = root.AddPropertyGroup();
group.AddProperty("Configuration", "Debug");
group.AddProperty("Platform", "x64");
// references
AddItems(root, "Reference", "System", "System.Core");
// items to compile
AddItems(root, "Compile", "test.cs");
var target = root.AddTarget("Build");
var task = target.AddTask("Csc");
task.SetParameter("Sources", "@(Compile)");
task.SetParameter("OutputAssembly", "test.dll");
root.Save("test.csproj");
Console.WriteLine(File.ReadAllText("test.csproj"));
}
private static void AddItems(ProjectRootElement elem, string groupName, params string[] items)
{
var group = elem.AddItemGroup();
foreach(var item in items)
{
group.AddItem(groupName, item);
}
}
}
请注意,这只会创建项目文件。它不会运行。此外,配置和平台之类的属性仅在Visual Studio生成的proj文件的上下文中才有意义。在这里,除非您按照Visual Studio自动执行的条件添加更多属性组,否则它们实际上不会做任何事情。
Note that this just creates the proj file. It doesn't run it. Also, properties like "Configuration" and "Platform" are only meaningful in the context of a proj file generated by Visual Studio. Here they won't really do anything unless you add more property groups with conditions the way Visual Studio does automatically.
就像我在评论中指出的那样,我认为这是错误的解决方法。您真的只想通过CodeDom进行动态源代码编译。
Like I indicated in my comments, I think this is wrong way to go about this. You really just want dynamic compilation of sources, which is available through CodeDom:
using System.CodeDom.Compiler;
class Program
{
static void Main(string[] args)
{
var provider = CodeDomProvider.CreateProvider("C#");
string[] sources = {
@"public abstract class BaseClass { public abstract void Test(); }",
@"public class CustomGenerated : BaseClass { public override void Test() { System.Console.WriteLine(""Hello World""); } }"
};
var results = provider.CompileAssemblyFromSource(new CompilerParameters() {
GenerateExecutable = false,
ReferencedAssemblies = { "System.dll", "System.Core.dll" },
IncludeDebugInformation = true,
CompilerOptions = "/platform:anycpu"
}, sources);
if (results.Errors.Count > 0)
{
Console.WriteLine("{0} errors", results.Errors.Count);
foreach(CompilerError error in results.Errors)
{
Console.WriteLine("{0}: {1}", error.ErrorNumber, error.ErrorText);
}
}
else
{
var type = results.CompiledAssembly.GetType("CustomGenerated");
object instance = Activator.CreateInstance(type);
type.GetMethod("Test").Invoke(instance, null);
}
}
}
