在Visual Studio中右键单击项目，选择项目属性->资源->添加资源->添加现有文件… 并将下面的代码包含到你的App.xaml.cs或等效程序中。

public App()
{
    AppDomain.CurrentDomain.AssemblyResolve +=new ResolveEventHandler(CurrentDomain_AssemblyResolve);
}

System.Reflection.Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    string dllName = args.Name.Contains(',') ? args.Name.Substring(0, args.Name.IndexOf(',')) : args.Name.Replace(".dll","");

    dllName = dllName.Replace(".", "_");

    if (dllName.EndsWith("_resources")) return null;

    System.Resources.ResourceManager rm = new System.Resources.ResourceManager(GetType().Namespace + ".Properties.Resources", System.Reflection.Assembly.GetExecutingAssembly());

    byte[] bytes = (byte[])rm.GetObject(dllName);

    return System.Reflection.Assembly.Load(bytes);
}

以下方法不使用外部工具，自动包含所有需要的DLL(不需要手动操作，一切都在编译时完成)

我在这里读了很多回答说使用ILMerge, ILRepack或Jeffrey Ritcher方法，但这些方法都不适合WPF应用程序，也不容易使用。

当你有很多DLL时，很难手动将你需要的DLL包含在你的exe中。我发现的最好的方法是由wegger在StackOverflow上解释的

为了清晰起见，Copy将他的答案粘贴在这里(全部归功于weged)

1)添加到你的。csproj文件:

<Target Name="AfterResolveReferences">
  <ItemGroup>
    <EmbeddedResource Include="@(ReferenceCopyLocalPaths)" Condition="'%(ReferenceCopyLocalPaths.Extension)' == '.dll'">
      <LogicalName>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</LogicalName>
    </EmbeddedResource>
  </ItemGroup>
</Target>

2)让你的Main Program.cs看起来像这样:

[STAThreadAttribute]
public static void Main()
{
    AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;
    App.Main();
}

3)添加OnResolveAssembly方法:

private static Assembly OnResolveAssembly(object sender, ResolveEventArgs args)
{
    Assembly executingAssembly = Assembly.GetExecutingAssembly();
    AssemblyName assemblyName = new AssemblyName(args.Name);

    var path = assemblyName.Name + ".dll";
    if (assemblyName.CultureInfo.Equals(CultureInfo.InvariantCulture) == false) path = String.Format(@"{0}\{1}", assemblyName.CultureInfo, path);

    using (Stream stream = executingAssembly.GetManifestResourceStream(path))
    {
        if (stream == null) return null;

        var assemblyRawBytes = new byte[stream.Length];
        stream.Read(assemblyRawBytes, 0, assemblyRawBytes.Length);
        return Assembly.Load(assemblyRawBytes);
    }
}

如果程序集只有托管代码，ILMerge可以将程序集组合为一个程序集。您可以使用命令行应用程序，或添加对exe的引用，并以编程方式合并。对于GUI版本，有Eazfuscator和。net z，这两个都是免费的。付费应用包括BoxedApp和SmartAssembly。

如果你必须将程序集与非托管代码合并，我建议使用SmartAssembly。我在使用SmartAssembly时从未遇到过问题，但在使用其他所有产品时都遇到过问题。在这里，它可以将所需的依赖项作为资源嵌入到主exe中。

你可以手动完成所有这些，不需要担心程序集是否被管理，或者通过将dll嵌入到资源中，然后依赖AppDomain的程序集ResolveHandler来混合模式。这是一种一站式解决方案，它采用了最坏的情况，即带有非托管代码的程序集。

static void Main()
{
    AppDomain.CurrentDomain.AssemblyResolve += (sender, args) =>
    {
        string assemblyName = new AssemblyName(args.Name).Name;
        if (assemblyName.EndsWith(".resources"))
            return null;

        string dllName = assemblyName + ".dll";
        string dllFullPath = Path.Combine(GetMyApplicationSpecificPath(), dllName);

        using (Stream s = Assembly.GetEntryAssembly().GetManifestResourceStream(typeof(Program).Namespace + ".Resources." + dllName))
        {
            byte[] data = new byte[stream.Length];
            s.Read(data, 0, data.Length);

            //or just byte[] data = new BinaryReader(s).ReadBytes((int)s.Length);

            File.WriteAllBytes(dllFullPath, data);
        }

        return Assembly.LoadFrom(dllFullPath);
    };
}

The key here is to write the bytes to a file and load from its location. To avoid chicken and egg problem, you have to ensure you declare the handler before accessing assembly and that you do not access the assembly members (or instantiate anything that has to deal with the assembly) inside the loading (assembly resolving) part. Also take care to ensure GetMyApplicationSpecificPath() is not any temp directory since temp files could be attempted to get erased by other programs or by yourself (not that it will get deleted while your program is accessing the dll, but at least its a nuisance. AppData is good location). Also note that you have to write the bytes each time, you cant load from location just 'cos the dll already resides there.

对于托管dll，您不需要写入字节，而是直接从dll的位置加载，或者只是读取字节并从内存加载程序集。像这样左右:

    using (Stream s = Assembly.GetEntryAssembly().GetManifestResourceStream(typeof(Program).Namespace + ".Resources." + dllName))
    {
        byte[] data = new byte[stream.Length];
        s.Read(data, 0, data.Length);
        return Assembly.Load(data);
    }

    //or just

    return Assembly.LoadFrom(dllFullPath); //if location is known.

如果程序集是完全非托管的，您可以查看此链接或此链接以了解如何加载此类dll。

如果它们实际上是托管程序集，您可以使用ILMerge。对于本地dll，您将有更多的工作要做。

试试这个:

https://github.com/ytk2128/dll-merger

在这里你可以合并所有32位dll /exe -即使它不是“。net”dll -所以对我来说更好，然后ilmerge为例…

我使用从.vbs脚本调用的csc.exe编译器。

在xyz.cs脚本中，在指令之后添加以下行(我的例子是用于Renci SSH):

using System;
using Renci;//FOR THE SSH
using System.Net;//FOR THE ADDRESS TRANSLATION
using System.Reflection;//FOR THE Assembly

//+ref>"C:\Program Files (x86)\Microsoft\ILMerge\Renci.SshNet.dll"
//+res>"C:\Program Files (x86)\Microsoft\ILMerge\Renci.SshNet.dll"
//+ico>"C:\Program Files (x86)\Microsoft CAPICOM 2.1.0.2 SDK\Samples\c_sharp\xmldsig\resources\Traffic.ico"

下面的.vbs脚本将提取ref、res和ico标记，以形成csc命令。

然后在Main中添加程序集解析器调用者:

public static void Main(string[] args)
{
    AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);
    .

.．.并在类中添加解析器本身:

    static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
    {
        String resourceName = new AssemblyName(args.Name).Name + ".dll";

        using (var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName))
        {
            Byte[] assemblyData = new Byte[stream.Length];
            stream.Read(assemblyData, 0, assemblyData.Length);
            return Assembly.Load(assemblyData);
        }

    }

我将vbs脚本命名为匹配.cs文件名(例如ssh。VBS查找ssh.cs);这使得运行脚本更容易很多次，但如果你不是像我这样的白痴，那么一个通用脚本可以从拖放中获取目标.cs文件:

    Dim name_,oShell,fso
    Set oShell = CreateObject("Shell.Application")
    Set fso = CreateObject("Scripting.fileSystemObject")

    'TAKE THE VBS SCRIPT NAME AS THE TARGET FILE NAME
    '################################################
    name_ = Split(wscript.ScriptName, ".")(0)

    'GET THE EXTERNAL DLL's AND ICON NAMES FROM THE .CS FILE
    '#######################################################
    Const OPEN_FILE_FOR_READING = 1
    Set objInputFile = fso.OpenTextFile(name_ & ".cs", 1)

    'READ EVERYTHING INTO AN ARRAY
    '#############################
    inputData = Split(objInputFile.ReadAll, vbNewline)

    For each strData In inputData

        if left(strData,7)="//+ref>" then 
            csc_references = csc_references & " /reference:" &         trim(replace(strData,"//+ref>","")) & " "
        end if

        if left(strData,7)="//+res>" then 
            csc_resources = csc_resources & " /resource:" & trim(replace(strData,"//+res>","")) & " "
        end if

        if left(strData,7)="//+ico>" then 
            csc_icon = " /win32icon:" & trim(replace(strData,"//+ico>","")) & " "
        end if
    Next

    objInputFile.Close


    'COMPILE THE FILE
    '################
    oShell.ShellExecute "c:\windows\microsoft.net\framework\v3.5\csc.exe", "/warn:1 /target:exe " & csc_references & csc_resources & csc_icon & " " & name_ & ".cs", "", "runas", 2
