意图:
想将项目用到的两个dll库文件(CryptEnDe.dll和ICSharpCode.SharpZipLib.dll)一同编译进exe中,并编译后仅一个exe程序就可以独立运行不再需要其它文件。
实现:
1、将两个dll库文件作为资源文件添加进项目中;
2、添加功能代码
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Reflection;
using System.IO;
namespace AutoUpdateServer.Core
{
/// <summary> 载入资源中的动态链接库(dll)文件
/// </summary>
static class LoadResourceDll
{
static Dictionary<string, Assembly> Dlls = new Dictionary<string, Assembly>();
static Dictionary<string, object> Assemblies = new Dictionary<string, object>();
static Assembly AssemblyResolve(object sender, ResolveEventArgs args)
{
//程序集
Assembly ass;
//获取加载失败的程序集的全名
var assName = new AssemblyName(args.Name).FullName;
//判断Dlls集合中是否有已加载的同名程序集
if (Dlls.TryGetValue(assName, out ass) && ass != null)
{
Dlls[assName] = null;//如果有则置空并返回
return ass;
}
else
{
throw new DllNotFoundException(assName);//否则抛出加载失败的异常
}
}
/// <summary> 注册资源中的dll
/// </summary>
public static void RegistDLL()
{
//获取调用者的程序集
var ass = new StackTrace(0).GetFrame(1).GetMethod().Module.Assembly;
//判断程序集是否已经处理
if (Assemblies.ContainsKey(ass.FullName))
{
return;
}
//程序集加入已处理集合
Assemblies.Add(ass.FullName, null);
//绑定程序集加载失败事件(这里我测试了,就算重复绑也是没关系的)
AppDomain.CurrentDomain.AssemblyResolve += AssemblyResolve;
//获取所有资源文件文件名
var res = ass.GetManifestResourceNames();
foreach (var r in res)
{
//如果是dll,则加载
if (r.EndsWith(".dll", StringComparison.OrdinalIgnoreCase))
{
try
{
if (r.Contains("CryptEnDe.dll")
|| r.Contains("CryptEnDe_d.dll"))
{
ExtractResourceToFile(r, PathUtils.GetUpdateDllPath() + @"/" + r.Substring(r.IndexOf('.') + 1));
}
var s = ass.GetManifestResourceStream(r);
var bts = new byte[s.Length];
s.Read(bts, 0, (int)s.Length);
var da = Assembly.Load(bts);
//判断是否已经加载
if (Dlls.ContainsKey(da.FullName))
{
continue;
}
Dlls[da.FullName] = da;
}
catch(Exception e)
{
//加载失败就算了...
}
}
}
}
private static void ExtractResourceToFile(string resourceName, string filename)
{
//if (!System.IO.File.Exists(filename))
{
using (System.IO.Stream s = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName))
{
using (System.IO.FileStream fs = new System.IO.FileStream(filename, System.IO.FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite))
{
byte[] b = new byte[s.Length];
s.Read(b, 0, b.Length);
fs.Write(b, 0, b.Length);
}
}
}
}
}
}
其中PathUtils.GetUpdateDllPath()函数为获取dll释放的路径,根据自己需要指定路径
public static string GetUpdateDllPath()
{
string strPath = @"C:/LTShiyi/cache/updatedll";
if (!Directory.Exists(strPath))
{
Directory.CreateDirectory(strPath);
}
return strPath;
}
3、在程序入口Program类中调用上面的接口函数
static Program()
{
AutoUpdateServer.Core.LoadResourceDll.RegistDLL();
}
4、编译即可。
