从静态方法访问类成员 [英] Accessing class member from static method

问题描述

我知道有很多的线程在谈论这一点，但到目前为止，我还没有找到一个直接帮助我的情况。我有类的成员，我需要从静态和非静态方法来访问。但是，如果成员都是非静态的，我似乎无法从静态方法得到他们。

 公共类SomeCoolClass
{
    公共字符串摘要=我要告诉你;    公共无效DoSomeMethod（）
    {
        字符串myInterval =摘要+，这是发生了什么事！
    }    公共静态无效DoSomeOtherMethod（）
    {
        字符串myInterval =摘要+它没有发生！
    }
}公共类MyMainClass
{
    SomeCoolClass myCool =新SomeCoolClass（）;
    myCool.DoSomeMethod（）;    SomeCoolClass.DoSomeOtherMethod（）;
}
 

你会如何建议我从任一类型的方法得到总结？

解决方案

  

你会如何建议我从任一类型的方法得到总结？

您需要通过 myCool 到 DoSomeOtherMethod - 在这种情况下，你应该让一个实例方法下手。

从根本上来说，如果它需要的类型的实例的状态，为什么你会使其静态的？

I know there are a lot of threads talking about this but so far I haven't found one that helps my situation directly. I have members of the class that I need to access from both static and non-static methods. But if the members are non-static, I can't seem to get to them from the static methods.

public class SomeCoolClass
{
    public string Summary = "I'm telling you";

    public void DoSomeMethod()
    {
        string myInterval = Summary + " this is what happened!";
    }

    public static void DoSomeOtherMethod()
    {
        string myInterval = Summary + " it didn't happen!";
    }
}

public class MyMainClass
{
    SomeCoolClass myCool = new SomeCoolClass();
    myCool.DoSomeMethod();

    SomeCoolClass.DoSomeOtherMethod();
}

How would you suggest I get Summary from either type of method?

解决方案

How would you suggest I get Summary from either type of method?

You'll need to pass myCool to DoSomeOtherMethod - in which case you should make it an instance method to start with.

Fundamentally, if it needs the state of an instance of the type, why would you make it static?
