我们有一种访问网络共享的方法.直接调用时此方法可以正常工作,但是当通过reflecton调用它时会得到System.IO.IOException.看起来用户上下文不可用于反射代码(请参阅下面的堆栈跟踪).有办法防止这种情况吗？

System.Reflection.TargetInvocationException: Exception has been thrown by 
the target of an invocation. ---> System.IO.IOException: Logon failure:
unknown user name or bad password.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.Directory.InternalGetFileDirectoryNames(String path, 
String userPathOriginal, String searchPattern, Boolean includeFiles,
Boolean includeDirs, SearchOption searchOption)
at System.IO.Directory.GetDirectories(String path, String searchPattern, 
SearchOption searchOption)

这很有效

   Library.Class obj =new Library.Class();
   obj.Execute(serverPath);

这不起作用

    Assembly assembly = Assembly.LoadFile(@"pathTo\Library.dll");
    Type type = assembly.GetType("Library.Class");
    MethodInfo executeMethod = type.GetMethod("Execute");
    object classInstance = Activator.CreateInstance(type, null);
    object[] parameterArray = new object[] { serverPath};
    executeMethod.Invoke(classInstance, parameterArray); …
