Leave only two decimal places after the dot.

Question

public void LoadAveragePingTime()
    {
        try
        {
            PingReply pingReply = pingClass.Send("logon.chronic-domination.com");
            double AveragePing = (pingReply.RoundtripTime / 1.75);

            label4.Text = (AveragePing.ToString() + "ms");                
        }
        catch (Exception)
        {
            label4.Text = "Server is currently offline.";
        }
    }

Currently my label4.Text get's something like: "187.371698712637".

I need it to show something like: "187.34"

Only two posts after the DOT. Can someone help me out?

Answer 1

string.Format is your friend.

String.Format("{0:0.00}", 123.4567);      // "123.46"

Answer 2

// just two decimal places
String.Format("{0:0.00}", 123.4567);      // "123.46"
String.Format("{0:0.00}", 123.4);         // "123.40"
String.Format("{0:0.00}", 123.0);         // "123.00"

edit

No idea why they used "String" instead of "string", but the rest is correct.
