从public static double中获取字符串 [英] get string from public static double

问题描述

大家希望你们结束快乐的一年..

i有问题，如果可以请你放手......

即时通讯使用Windows应用程序查看连接雕像

它给结果e带（100,60 ,,,或0）

但我想如果totoaltime = 0它显示字符串给出一些文字

hi everyone wish happy ending year for you guys..
i have question if you could please give hand...
im using windows application for checking connection statues
it give the result e with either (100,60,,, or 0)
but i want if totoaltime=0 it show string give some text

 private void buttonX1_Click(object sender, EventArgs e)
        {
           
richTextBox1.Text += "return is ={"+(pingcheck(Ipinput1.Text,Convert.ToInt32(Txpackage1.Text)))+"}"+Environment.NewLine;
          
           
          
 richTextBox2.Text +=" return is={"+(pingcheck(Ipinput2.Text, Convert.ToInt32(Txtpackag2.Text)))+"}" + Environment.NewLine;
           }
           
public static double pingcheck(string host, int echonum)//i tried with (string host, int echonum,string getipstatues) but it won't retrieve 
        {
            long totaltime = 0;
            int timeout = 120;
          
            Ping pingsender = new Ping();

            for (int i = 0; i < echonum; i++)
            {
                PingReply replay = pingsender.Send(host, timeout);
                if (replay.Status == IPStatus.Success)
                {
                    totaltime += replay.RoundtripTime;
                }
                else if(totaltime==0)
                {
//messagebox.show("your connection is not available "); here it will show every time when totaltime =0
                    string getipstatue = "the connectin is not available ";//but i wanna show this this text not messagebox
                }
              
               
            }
            return totaltime + echonum;        
        }

推荐答案

RoundTripTime 属性和你的 totaltime 不是 double 值 - 它们很长，这意味着int64 - 所以CHill60说，你可以直接把它比作0没有任何问题：

The RoundTripTime property and your totaltime aren't double values - they are long, which means int64 - so as CHill60 says, you can compare it directly to 0 without any problems:

else if(totaltime == 0)

但是设置字符串不会显示任何内容。所以尝试

But just setting a string doesn't display anything. So try

}
else if(totaltime == 0)
{
    MessageBox.Show("The connection is not available ");
}

这里我得到了解决方案，如果有人知道它...谢谢你多了

here i got solution if someone neet id it... thanks for you sou much

public static bool PingCheck(string host, int echonum, out double approximateTime) 
{
    long totaltime = 0;
    int timeout = 120;
    Ping pingsender = new Ping();

    for (int i = 0; i < echonum; i++)
    {
        PingReply replay = pingsender.Send(host, timeout);
        if (replay.Status == IPStatus.Success)
        {
            totaltime += replay.RoundtripTime;
        } 
        else 
        {
            approximateTime = 0.0;
            return false;
        }
    }

    
    approximateTime = (double)totaltime / echonum;
    return true;
}

private void buttonX1_Click(object sender, EventArgs e)
{
    double appTime;
    if (PingCheck("8.8.8.", 1, out appTime))
    {
        richTextBox1.Text += appTime.ToString("F2") + Environment.NewLine;
    } else {
        richTextBox1.Text += "the connectin is not available";
    }
}
