Question

In my class “Server.cs”, I want to access a textbox from a form. I tried using this code:

ServerWindow.WriteChatlog(encoder.GetString(message, 0, bytesRead));

But I got this error:

An object reference is required for the non-static field, method, or property 'Chat_Server.ServerWindow.WriteChatlog(string)

ServerWindows.WriteChatlog(string text) looks like this:

public void WriteChatlog(string text)
        {
            textBox1.Text += text + Environment.NewLine;
        }

Now I tried doing that directly from where I was using ServerWindow.WriteChatlog method, but it didn’t work.

They are both non-static

You need to call WriteChatLog on an instance of the ServerWindow class. Ex:

ServerWindow servwin = new ServerWindow();
servwin.WriteChatlog(encoder.GetString(message, 0, bytesRead));
