Accessing class member from static method

Question

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 fro

Answer 1

You can't access instance members from a static method. The whole point of static methods is that they're not related to a class instance.

Answer 2

You simply can't do it that way. Static methods cannot access non static fields.

You can either make Summary static

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

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

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

Or you can pass an instance of SomeCoolClass to DoSomeOtherMethod and call Summary from the instance you just passed :

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

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

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

Anyway I can't really see the goal you're trying to reach.

Answer 3

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?
