类名作为参数? [英] class name as parameter?
问题描述
我有3个具有相同方法组的单例类。
I have 3 singleton classes with same set of methods.
在我的调用函数中,我写的是:
in my calling function, I am writing:
十进制结果= 0;
开关(myParam)
switch (myParam)
{
案例值1:
result = MyClass1.Instance.GetData(); break;
result = MyClass1.Instance.GetData(); break;
case valu2:
case valu2:
result = MyClass2.Instance.GetData(); break;
result = MyClass2.Instance.GetData(); break;
默认值:
result = MyClass3.Instance.GetData();休息;
result = MyClass3.Instance.GetData(); break;
}
返回结果;
我想用一个语句替换上面的开关,并将className作为参数传递给我上面的调用函数。以下代码是否适用于单身人士?如果没有,我该怎么做?
I want to replace the above switch with a single statement and pass className as parameter to my above calling function. Will the below code work for a singleton? If not, how would I do it?
object myObject = Activator.CreateInstance(className);
object myObject = Activator.CreateInstance(className);
decimal result = myObject.GetData();
decimal result = myObject.GetData();
谢谢。
推荐答案
C#不是脚本语言。
C# is not a scripting language.
你想要什么是脚本的典型代表。如果你在互联网上搜索,你会发现它被问过一千次。
What you want is typical for scripting. If you search on Internet you can find it asked thousand times.
然而,一个课程不是一个对象,所以你永远找不到真正令人满意的答案。
However, a class is not an object so you will never find a real satisfying answer.
请记住,C#类需要始终被实例化(它只是模板)。在编译时静态或使用"新"静态运行时的关键字。
Keep in mind C# classes needs always to be instanced to be used (it are just templates). Either static at compile time or with the "new" keyword at runtime.
