# 背景 #

在很多业务场景下都需要根据网络状态执行不同的操作，而最常用和效率比较高的办法就是使用ping，那么在C\#代码中如何实现这块逻辑呢？

# 代码实现 #

编写一个工具类TPTools.cs，如下：

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Net.NetworkInformation;
    using System.Text;
    
    namespace WindowsFormsApplication1
    { 
        public class IPTools
        { 
            #region 检测某个IP或域名是否可以Ping通
    
            /// <summary>
            /// 检测某个IP或域名是否可以Ping通
            /// </summary>
            /// <param name="strIpOrDName">IP或域名</param>
            /// <returns>true为通，false为不通</returns>
            public static bool PingIpOrDomainName(string strIpOrDName)
            { 
                try
                { 
                    Ping objPingSender = new Ping();
                    PingOptions objPinOptions = new PingOptions();
                    objPinOptions.DontFragment = true;
                    string data = "";
                    byte[] buffer = Encoding.UTF8.GetBytes(data);
                    int intTimeout = 120;
                    PingReply objPinReply = objPingSender.Send(strIpOrDName, intTimeout, buffer, objPinOptions);
                    string strInfo = objPinReply.Status.ToString();
                    if (strInfo == "Success")
                    { 
                        return true;
                    }
                    else
                    { 
                        return false;
                    }
                }
                catch (Exception)
                { 
                    return false;
                }
            }
    
            #endregion
        }
    }

# 测试代码 #

private void button1_Click(object sender, EventArgs e)
    { 
        string ip1 = "127.0.0.1";
        bool result = IPTools.PingIpOrDomainName(ip1);
        Console.WriteLine("ping {0} result is {1}!", ip1, result);
    
        string ip2 = "www.baidu.com";
        result = IPTools.PingIpOrDomainName(ip2);
        Console.WriteLine("ping {0} result is {1}!", ip2, result);
    
        string ip3 = "192.168.5.123";
        result = IPTools.PingIpOrDomainName(ip3);
        Console.WriteLine("ping {0} result is {1}!", ip3, result);
    }
