问题描述

这个班级的工作非常好，有32位但是不用64位



任何人都可以帮我解决这个问题吗？

this class work excellent with 32 bit but dosn''t with 64 bit

any body can help me to fix it ?

using System.Net;
using System.Runtime.InteropServices;

namespace testPing

    class Class1
    {
        public static class ServerStatus

                    IntPtr h = IcmpCreateFile();
                    int req = 123456789;
                    ICMP_ECHO_REPLY rep = new ICMP_ECHO_REPLY();
                    uint retval = IcmpSendEcho(h, addr, ref req, 4, IntPtr.Zero,
                    ref rep, 56, 10);
                    IcmpCloseHandle(h);
                    return (retval != 0 && rep.Status == IP_SUCCESS);
                }

这个问题出了什么问题： http：// msdn .microsoft.com / zh-cn / library / system.net.networkinformation.ping.aspx [ ^ ]？



PS：不工作不是错误信息，也不是具体结果。

PS2：你检查过这些api调用的64位版本是否与32位系统相同？阅读本文： http://msdn.microsoft.com /en-us/library/windows/desktop/aa366050(v=vs.85).aspx [ ^ ]，并寻找在64位平台上......

And what''s wrong with this one: http://msdn.microsoft.com/en-us/library/system.net.networkinformation.ping.aspx[^]?

PS: doesn''t work is not an error message, nor a concrete result.
PS2: have you checked if the 64 bit version of those api calls is the same as in 32 bit systems? Read this one: http://msdn.microsoft.com/en-us/library/windows/desktop/aa366050(v=vs.85).aspx[^], and look for "On a 64-bit platform..."
