如何在.NET 3.5中进行动态对象创建和方法调用

public class MyClass
{
    public string MyMethod(string input)
    {
        return "Hello, " + input;
    }
}

Type myClassType = Type.GetType("MyClass");
object myClassInstance = Activator.CreateInstance(myClassType);

MethodInfo myMethodInfo = myClassType.GetMethod("MyMethod");
object result = myMethodInfo.Invoke(myClassInstance, new object[] { "World" });
