将DLL加载到单独的AppDomain中

using System;
using System.Reflection;

public class Program
{
    static void Main(string[] args)
    {
        AppDomain domain = AppDomain.CreateDomain("MyDomain");
        domain.AssemblyResolve += Domain_AssemblyResolve;
        domain.DoCallBack(LoadAssembly);
        AppDomain.Unload(domain);
    }

    private static void LoadAssembly()
    {
        string assemblyPath = @"C:\MyAssembly.dll";
        Assembly assembly = Assembly.LoadFrom(assemblyPath);
        Type type = assembly.GetType("MyNamespace.MyClass");
        object obj = Activator.CreateInstance(type);
        type.GetMethod("MyMethod").Invoke(obj, null);
    }

    private static Assembly Domain_AssemblyResolve(object sender, ResolveEventArgs args)
    {
        string assemblyPath = @"C:\MyAssembly.dll";
        return Assembly.LoadFrom(assemblyPath);
    }
}
