点后，只留下两位小数 [英] Leave only two decimal places after the dot

问题描述

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.";
        }
    }

目前我label4.Text获取的是这样的：187.371698712637

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

我需要它来显示类似：187.34

I need it to show something like: "187.34"

后点只有两个职位。有人可以帮我吗？

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

推荐答案

的String.Format 是你的朋友。

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