[常用]將所有dll檔封裝進exe檔(WPF)

一般我們寫程式的時候都會用到許多dll
但是把程式交出去的時候如果有一堆dll會很難管理，也不是很好看

這時候就需要把dll封裝進程式執行檔裡面

1.修改Project.csproj

	參考自http://www.digitallycreated.net/Blog/61/combining-multiple-assemblies-into-a-single-exe-for-a-wpf-application
	在最底部增加這幾行
	<Target Name="AfterResolveReferences">
	<ItemGroup>
	<EmbeddedResource Include="@(ReferenceCopyLocalPaths)" Condition="'%(ReferenceCopyLocalPaths.Extension)' == '.dll'">
	<LogicalName>%(ReferenceCopyLocalPaths.DestinationSubDirectory)%(ReferenceCopyLocalPaths.Filename)%(ReferenceCopyLocalPaths.Extension)</LogicalName>
	</EmbeddedResource>
	</ItemGroup>
	</Target>

2.右鍵點選參考底下的dll，把複製到本機這個屬性改為False，該dll就不會一起複製到程式執行的資料夾內。
   但此動作會使得程式參考不到該dll檔

3.將dll檔加進Resources內，建置方式選擇內嵌資源，就跟一般放影像檔、音效檔一樣，會把dll封裝進exe執行檔內。
   但程式呼叫到該dll時不會自動找到Resources內的dll檔，必須自行對應

4.新建一支Program.cs檔，取代App.xaml.cs成為專案起始檔(右鍵點專案可以設定起始檔)

	using System;
	using System.Collections.Generic;
	using System.Globalization;
	using System.IO;
	using System.Linq;
	using System.Reflection;
	using System.Text;
	namespace MyProject
	{
	public class Program
	{
	[STAThreadAttribute]
	public static void Main()
	{
	var assemblies = new Dictionary<string, Assembly>();
	var executingAssembly = Assembly.GetExecutingAssembly();
	var resources = executingAssembly.GetManifestResourceNames().Where(n => n.EndsWith(".dll"));
	//設定dll的參考路徑以供程式執行時對應
	foreach (string resource in resources)
	{
	using (var stream = executingAssembly.GetManifestResourceStream(resource))
	{
	if (stream == null)
	continue;
	var bytes = new byte[stream.Length];
	stream.Read(bytes, 0, bytes.Length);
	try
	{
	assemblies.Add(resource, Assembly.Load(bytes));
	}
	catch (Exception ex)
	{
	System.Diagnostics.Debug.Print(string.Format("Failed to load: {0}, Exception: {1}", resource, ex.Message));
	}
	}
	}
	//當程式參考不到dll時會觸發，將我們對應好的dll位置回傳
	AppDomain.CurrentDomain.AssemblyResolve += (s, e) =>
	{
	var assemblyName = new AssemblyName(e.Name);
	var path = string.Format("{0}.dll", assemblyName.Name);
	//不知道為什麼，自行加在Resources內的dll都會把路徑全部寫進名稱，所以這邊我自己把路徑補上以免對應不到
	if (assemblies.ContainsKey(path) || assemblies.ContainsKey("Projectname.Resources."+path))
	{
	return assemblies["Projectname.Resources." + path];
	}
	return null;
	};
	App.Main();
	}
	}
	}

完成以上步驟後，再建置程式，就會發現dll檔都不見了，而exe檔明顯變肥
