如何在 wpf/winforms 应用程序中将 DLL 与 .exe 结合(带图片) [英] How to combine DLLs with .exe inside of a wpf / winforms application (with pictures)
问题描述
如何将多个dll合并到主.exe文件中?(不使用第三方程序)
更新 3
.Net 内置了这个
5 - 现在到代码部分:
首先导入这个命名空间
vb.net
导入 System.Reflectionc#
使用 System.Reflection;在构造函数(vb中的[Sub New])中添加这段代码
Vb.net
Public Sub New()AddHandler AppDomain.CurrentDomain.AssemblyResolve, AddressOf OnResolveAssembly结束子c#.net
公共应用程序(){AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;}然后添加OnResolveAssembly函数
vb.net

更新 DLL
1 - 只需将您的新 dll 拖放到与旧 dll 相同的文件夹中，然后接受覆盖(确保检查 [Build Action = Embedded Resources] AND [Copy To Output Directory = Do not复制])
添加新的 DLL
只需重复步骤 1 =>3

How to combine multiple dlls into the main .exe file? (without using third-party programs)
Update 3
.Net has this built in https://docs.microsoft.com/en-us/dotnet/core/deploying/single-file
Update 2
you don't even have to include the dlls as embedded resources at all, just use Fody.Costura and it will resolve the referenced assemblies and auto-include them
Also if you are using .net core 3+ you can use the Single file executable & Assembly linking features
Update
if you want an easy tool to merge the assemblies without worrying about doing ANY work at all then Fody.Costura is the best choice you have, as all you need to do is just include the dlls and change their Build Action to Embedded Resource and it will work right away.
1 - make a folder that contains all of the Dlls or place them separately as you like
2 - Click on each DLL from the "Solution Explorer" and make sure they have these properties
Build Action = Embedded Resources
Copy To Output Directory = Do not copy
3 - Go to : Project > Properties > References , And make sure every Dll you add has the same name as the assembly like this :
In References :-
In Solution Explorer :-
Note :-
It's Better to Make copy local = True in references as it will give you an updated DLL each time you publish the project
Now at this point you have your DLLs added to the EXE , all is remaining now is to tell the program how to read these DLLs from the EXE (that's why we made build action = Embedded resources)
4 - In Solution Explorer Open your (Application.xaml.vb) file ([App.xaml.cs] in c#)
OR
Go To : Project > Properties > Application > View Application Events
Now in this page we are going to handle the very first event of the application (Construction event) to tell the program how to handle the assemblies we add as DLLs before loading/reading them by using the AssemblyResolve Event
Check this MSDN page for more Info about the AssemblyResolve Event https://msdn.microsoft.com/en-us/library/system.appdomain.assemblyresolve(v=vs.110).aspx
5 - Now to The code part :
first of all Import this namespace
vb.net
Imports System.Reflection
c#
using System.Reflection;
In the Constructor ([Sub New] in vb) add this code
Vb.net
Public Sub New()
AddHandler AppDomain.CurrentDomain.AssemblyResolve, AddressOf OnResolveAssembly
End Sub
c#.net
public App()
{
AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;
}
Then add the OnResolveAssembly Function
vb.net
''' <summary>
''' Tells the program that the Assembly it's Seeking is located in the Embedded resources By using the
''' <see cref="Assembly.GetManifestResourceNames"/> Function To get All the Resources
''' </summary>
''' <param name="sender"></param>
''' <param name="args"></param>
''' <returns></returns>
''' <remarks>Note that this event won't fire if the dll is in the same folder as the application (sometimes)</remarks>
Private Shared Function OnResolveAssembly(sender As Object, args As ResolveEventArgs) As Assembly
Try
'gets the main Assembly
Dim parentAssembly = Assembly.GetExecutingAssembly()
'args.Name will be something like this
'[ MahApps.Metro, Version=1.1.3.81, Culture=en-US, PublicKeyToken=null ]
'so we take the name of the Assembly (MahApps.Metro) then add (.dll) to it

return Assembly.Load(block);
}
} else {
return null;
}
} catch (Exception ex) {
return null;
}
}
6 - now publish the application or build it and all your dlls will be embedded in a single EXE file (with some extra milliseconds delay to load them)
To Update the DLLs
1 - Simply drag and drop your new dll to the Solution Explorer as the same folder as the old dll then accept the override (make sure to check that [Build Action = Embedded Resources] AND [Copy To Output Directory = Do not copy])
To Add New DLLs
just repeat step 1 => 3
