反射出TargetException 错误，请问何解？急，在线等，谢谢!!
调用端：
string filepath = @ "E:\VS2005\DataCollector\DataCollector\Components\DataAnalyzer.dll ";
String test = "分析中 ";
Assembly myDllAssembly = Assembly.LoadFrom(filepath);
Type dllType = myDllAssembly.GetType( "DataAnalyzer.Goodoon ");
if (dllType!=null)
{
MethodInfo mi = dllType.GetMethod( "kkk ");
String nnn = (String)mi.Invoke(dllType, null); <----出错，TargetException
Console.WriteLine(nnn);
}


在DLL那边：
public String kkk()
{
String teststr = "abc ";
return teststr;
}


在出错行那里提示：对象与目标类型不匹配，TargetException

请问何解？谢谢

[解决办法]
if (dllType!=null)
{
MethodInfo mi = dllType.GetMethod( "kkk ");
object o=Activator.CreateInstance(dllType);
String nnn = (String)mi.Invoke(o, null);
Console.WriteLine(nnn);
}


改成这样试试.
