Question

我的类名是字符串格式，我需要动态执行函数并将结果转换为动态

    Type type = Type.GetType(method.NameSpace + "." + method.ClassName, false);
    //

      Type calledType = Type.GetType(namespaceName + "." + className + "," + assemblyName);
             //this function return object type of class type which is I've created from string className      
var result=  calledType.InvokeMember(
                                methodName,
                                BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Static,
                                null,
                                null,
                                obj);

或AlTERNAtely

public T CAST<T>(Object o){
//some mechanism
}

CAST<type >(result);

给出预期的类型或命名空间名称.. 如何将动态生成的类类型转换为泛型类型

现在我需要将var结果转换为Type类型（动态类）。怎么样？

我认为你需要的是Convert.ChangeType。以下是使用MyMethod参数调用string[]的示例。

public static string MyMethod(string s, int i, DateTime d)
{
    return s + " " + i + " " + d.ToString();
}

public T Execute<T>()
{
    //They are all strings in object array
    object[] myparams = new object[] {"test","3","04/03/2012" };

    Type[] types = this.GetType()
                       .GetMethod("MyMethod")
                       .GetParameters()
                       .Select(p=>p.ParameterType)
                       .ToArray();

    object result = 
        this.GetType().InvokeMember(
        "MyMethod",
        BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Static,
        null,
        this,
        myparams.Select((s,i)=>Convert.ChangeType(s,types[i])).ToArray()
        );

    return (T)result;
}
