Question

I’m new to C# and GUI programming, so I have a feeling this is a simple one, but the docs on DisplayMember are confusing me.

List<string[]> serverInfo = new List<string[]>();
serverInfo.Add(new string[] { "server one", "1.2.3.4", "12345" });
serverInfo.Add(new string[] { "server two", "1.2.3.4", "12346" });
serverInfo.Add(new string[] { "server three", "1.2.3.5", "12343" });

ComboBox serverPickList = new ComboBox();
serverPickList.DataSource = serverInfo;
serverPickList.DisplayMember = "???";

The ComboBox’s options should be “server one”, “server two”, and “server three”, but I still want the string[] arrays bound as I’ll be processing them.

Why won’t you make a class out of it?

class ServerInfo
{
    public string Name { get; set; }
    public string OtherStuff { get; set; }
    public string OtherStuff2 { get; set; }

    public ServerInfo(string name, string otherStuff, string otherStuff2)
    {
        this.Name = name;
        this.OtherStuff = otherStuff;
        this.OtherStuff2 = otherStuff2;
    }
}

And then:

List<ServerInfo> serverInfo = new List<ServerInfo>();
serverInfo.Add(new ServerInfo("server one", "1.2.3.4", "12345"));
serverInfo.Add(new ServerInfo("server two", "1.2.3.4", "12346"));
serverInfo.Add(new ServerInfo("server three", "1.2.3.5", "12343"));

ComboBox serverPickList = new ComboBox();
serverPickList.DataSource = serverInfo;
serverPickList.DisplayMemeber = "Name";
