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


    WScript.Quit(0)

.NET Core 3.0原生支持编译为单个.exe

该特性是通过在项目文件(.csproj)中使用以下属性启用的:

    <PropertyGroup>
        <PublishSingleFile>true</PublishSingleFile>
    </PropertyGroup>

这无需任何外部工具即可完成。

详见我对这个问题的回答。

杰弗里·里希特的节选非常好。简而言之，将库作为嵌入式资源添加，并在其他任何事情之前添加回调。下面是我放在控制台应用程序Main方法开头的一个版本的代码(在他的页面的评论中找到)(只是要确保任何使用库的调用都是在不同的方法中)。

AppDomain.CurrentDomain.AssemblyResolve += (sender, bargs) =>
        {
            String dllName = new AssemblyName(bargs.Name).Name + ".dll";
            var assem = Assembly.GetExecutingAssembly();
            String resourceName = assem.GetManifestResourceNames().FirstOrDefault(rn => rn.EndsWith(dllName));
            if (resourceName == null) return null; // Not found, maybe another handler will find it
            using (var stream = assem.GetManifestResourceStream(resourceName))
            {
                Byte[] assemblyData = new Byte[stream.Length];
                stream.Read(assemblyData, 0, assemblyData.Length);
                return Assembly.Load(assemblyData);
            }
        };

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);
}
