有时候我们想让程序的exe文件和dll文件分开在不同目录，这时候可以有４种方法
app.config中配置

<runtime>
<gcConcurrent enabled="true" />
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<publisherPolicy apply="yes" />
<probing privatePath="32;64" />
</assemblyBinding>
</runtime>
AppendPrivatePath
AppDomain.CurrentDomain.AppendPrivatePath来设置
1
AppDomain.CurrentDomain.AppendPrivatePath( strRelatedDirectory );
PrivateBinPath
new AppDomainSetup().PrivateBinPath 来设置

if (AppDomain.CurrentDomain.IsDefaultAppDomain())
{
string appName = AppDomain.CurrentDomain.FriendlyName;
var currentAssembly = Assembly.GetExecutingAssembly();
AppDomainSetup setup = new AppDomainSetup();
setup.ApplicationBase = System.Environment.CurrentDirectory;
setup.PrivateBinPath = "Libs";
setup.ConfigurationFile = setup.ApplicationBase +
string.Format("\\Config\\{0}.config", appName);
AppDomain newDomain = AppDomain.CreateDomain("NewAppDomain", null, setup);
int ret = newDomain.ExecuteAssemblyByName(currentAssembly.FullName, e.Args);
AppDomain.Unload(newDomain);
Environment.ExitCode = ret;
Environment.Exit(0);
return;
}
可有时候又不想把他放在config文件上，只想用代码来实现，第二中方法发现已经过期，第三种方法MSDN语焉不详的，网上也没有什么资料，目前就用第四种方法
AssemblyResolve事件
AppDomain有个AssemblyResolve事件，加载dll失败的时候触发，可以在这个事件里面处理

AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;
static System.Reflection.Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
string path = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"Libs\");
path = System.IO.Path.Combine(path, args.Name.Split(',')[0]);
path = String.Format(@"{0}.dll", path);
return System.Reflection.Assembly.LoadFrom(path);
}
