我无法访问在课堂上声明的变量

Question

This is my c# code

namespace abc {
    public class def: SchedulerClient 
    {
        public string key; {}
        public static void send(string abc) 
        {
            lots of code...........
            key = string;
        }
    }    
}

I am getting an error when i try to store a string value in my variable key which i have declared as "public".

This is the error i get:

An object reference is required for the non-static field, method, or property 'abc .def.Dkey'

How do i overcome this?

Answer 1

You can overcome it by making your method not static:

public void send(string abc) 
{
    lots of code...........
    key = stringValue;
}

or by making the field static:

public static string key;

At any rate, I think you need to think about your design and figure out what needs to be static and what doesn't.

Answer 2

your method is static but your key is an instance. you cannot access instance properties or methods in a static reference.

either make them both static or make them both non static

Answer 3

Static members are accessible only in static methods and static method can access static members as well as non-static members. Please make the change accordingly.
