本文实例讲述了C#实现动态加载dll的方法。分享给大家供大家参考。具体实现方法如下：

namespace Alif.CommonAPI.DynamicLoadAssembly
{
    public class AssemblyDynamicLoader<T>
    {
        private AppDomain appDomain;

        private DynamicRemoteLoadAssembly<T> remoteLoader;

        public T InvokeMethod(string assemblyName, string assemblyPath, string assemblyConfigFilePath, string fullClassName, string methodName, params object[] args)
        {
            AppDomainSetup setup = new AppDomainSetup();
            setup.ApplicationName = \"ApplicationLoader\";
            setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory + @\"bin\\\";
            //setup.PrivateBinPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, \"private\");
            setup.CachePath = setup.ApplicationBase;
            setup.ShadowCopyFiles = \"true\";
            if (assemblyConfigFilePath != string.Empty)
            {
                setup.ConfigurationFile = AppDomain.CurrentDomain.BaseDirectory + assemblyConfigFilePath;
            }
            setup.ShadowCopyDirectories = setup.ApplicationBase;
            setup.LoaderOptimization = LoaderOptimization.SingleDomain;

            this.appDomain = AppDomain.CreateDomain(\"ApplicationLoaderDomain\", null, setup);
            String name = Assembly.GetExecutingAssembly().GetName().FullName;

            this.remoteLoader = (DynamicRemoteLoadAssembly<T>)this.appDomain.CreateInstanceAndUnwrap(name, typeof(DynamicRemoteLoadAssembly<T>).FullName);

            assemblyName = AppDomain.CurrentDomain.BaseDirectory + assemblyPath + assemblyName;

            return this.remoteLoader.InvokeMethod(assemblyName, fullClassName, methodName, args);
        }

        /// <summary>
        ///
        /// </summary>
        public void Unload()
        {
            try
            {
                AppDomain.Unload(this.appDomain);
                this.appDomain = null;
            }
            catch (CannotUnloadAppDomainException ex)
            {

            }
        }
    }
}
