1. 方法1：把相關(guān)的第三方dll作為程序資源嵌入到EXE中，在程序運行的時候，從資源文件中輸出到程序執(zhí)行目錄即可。

   
   (圖1：示例項目，ThirdPartydlldemo.dll作為第三方資源，Build Action屬性設置為" Embedded Resource")

   然后在Program.cs里面聲明個靜態(tài)構(gòu)造函數(shù)，在該方法里面把第三方dll輸出到程序目錄，這樣在調(diào)用第三方dll方法的時候，相關(guān)環(huán)境已經(jīng)初始化完畢了。

      1: private static void ExtractResourceToFile(string resourceName, string filename)
      2:    {
      3:          if (!System.IO.File.Exists(filename))
      4:             using (System.IO.Stream s = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName))
      5:             usng (System.IO.FileStream fs = new System.IO.FileStream(filename, System.IO.FileMode.Create))
      6:             {
      7:                    byte[] b = new byte[s.Length];
      8:                    s.Read(b, 0, b.Length);
      9:                    fs.Write(b, 0, b.Length);
     10:              }
     11:     }

    

      1: static Program()
      2:       {
      3:           ExtractResourceToFile("EmbeddedDLL2ExeDemo.ThirdPartyDllDemo.dll",
      4:               "ThirdPartyDllDemo.dll");
      5:       }

   這樣就ok了。

2. 方法2：是用Ilmerge這個微軟提供的工具，直接把相關(guān)的dll嵌入到目標exe中，而且程序運行時候，不像方法1會把相關(guān)的dll輸出到可執(zhí)行目錄下，它直接讓.net運行時到程序的資源中去找相關(guān)的dll引用，以下是Ilmerge的介紹：

   This document describes the ILMerge utility which merges multiple .NET assemblies into a single assembly. However, some .NET assemblies may not be able to be merged because they may contain features such as unmanaged code. I would highly recommend using peverify (the .NET Framework SDK tool) on the output of ILMerge to guarantee that the output is verifiable and will load in the .NET runtime.

   ILMerge is packaged as a console application. But all of its functionality is also accessible programmatically. Note that Visual Studio does allow one to add an executable as a reference, so you can write a client that uses ILMerge as a library.

   ILMerge takes a set of input assemblies and merges them into one target assembly. The first assembly in the list of input assemblies is the primary assembly. When the primary assembly is an executable, then the target assembly is created as an executable with the same entry point as the primary assembly. Also, if the primary assembly has a strong name, and a .snk file is provided, then the target assembly is re-signed with the specified key so that it also has a strong name.

   Note that anything that depended upon any of the names of the input assemblies, e.g., configuration files, must be updated to refer instead to the name of the target assembly.

   Any Win32 Resources in the primary assembly are copied over into the target assembly.

   There are many options that control the behavior of ILMerge. These are described in the next section.

   Ilmerge 相關(guān)的命令行參數(shù)是:

   ilmerge [/lib:directory]* [/log[:filename]] [/keyfile:filename [/delaysign]] [/internalize[:filename]] [/t[arget]:(library|exe|winexe)] [/closed] [/ndebug] [/ver:version] [/copyattrs [/allowMultiple]] [/xmldocs] [/attr:filename] ([/targetplatform:<version>[,<platformdir>]]|v1|v1.1|v2|v4) [/useFullPublicKeyForReferences] [/zeroPeKind] [/wildcards] [/allowDup[:typename]]* [/allowDuplicateResources] [/union] [/align:n] /out:filename <primary assembly> [<other assemblies>...]

   其中目標exe或者程序集，要放在輸入的程序集里面的第一位置，其他dll放在它之后，其中/out:參數(shù)是必須的，其他參數(shù)可以參考文檔。

   如圖1 示例，命令行參數(shù)是：

   ilmerge EmbeddedDLL2ExeDemo.exe ThirdPartyDllDemo.dll /ndebug /out:EmbeddedDll2Ex
   eDemo.exe

   這樣即可，該方法比方法1更完美，不過這個Ilmerge 在使用的時候還有一些不足的地方，比如/ver:version這個參數(shù)設置后沒有效果；

   ilmerge就用自己把它引用到的兩個dll嵌軟到它自身里面了。

方法3：使用.Net混淆器都附帶這樣的功能，可以把多個dll整合到一個可執(zhí)行文件中。
