Use reflection to call methods in any .net library

The function is as follows, with comments, please check it yourself :)
Note:
1. ReturnMessage is a class I wrote myself. Please check my other articles for its function. I also attached this class at the back.
2. Through NameSpaceAndClassName and MethodName, you can actually accurately locate a method. For example, when calling namespace1.Class1.Main in abc.dll, the call is CallAssembly("abc.dll","namespace1.Class1","Main",null )
public static ReturnMessage CallAssembly(string Path,string NameSpaceAndClassName,string MethodName,object[] Parameters)
{
try
{
Assembly Ass=Assembly.LoadFrom(Path);//Load the file (not limited to dll, exe can also be used, as long as it is .net)
Type TP=Ass.GetType(NameSpaceAndClassName);//NameSpaceAndClassName is "namespace.classname", such as "namespace1.Class1"
MethodInfo MI=TP.GetMethod(MethodName);//MethodName is the method name to be called, such as "Main"
object MeObj=System.Activator.CreateInstance(TP);
MI.Invoke(MeObj,Parameters);//Parameters is the parameter list passed in when calling the target method
return new ReturnMessage(true,"successfully called",1);
}
catch(Exception e)
{
return new ReturnMessage(false,"An exception occurred, the message is: "+e.Message,-1,e);
}
}
