Question

I get an error message “An object reference is required for the non-static field, method, or property….” for calling Refresh function :

// Status

    public static string Status 
    {
        get 
          { 
              return status; 
          }
        set 
        {
            status = value;
            Refresh();
        } 
    }

    private void Refresh()
    {
        lblStatus.Text = Status.ToString();
    }

Answer 1

Simply make the Status property non-static. Clearly you do not share this property across all the instances of that class. It looks like you are working with a control or a page class and you trying to call other instance methods or properties also.

So this will fix the compilation error.

public string Status
