问题描述
限时送ChatGPT账号..在运行 Windows 7 x64 和 VS2012 U1 并使用 .Net 4 的两个系统上,如果我调用 UdpClient 或 TcpClient,我会收到错误提供的参数无效".
On two systems running Windows 7 x64 and VS2012 U1 and using .Net 4 I get the error "An invalid argument was supplied" if I call UdpClient or TcpClient.
我已经尝试了多个端口,并且已经验证这些端口尚未绑定,但我每次都遇到相同的错误.
I've tried a number of ports and I've verified that the ports are not already bound but I get the same error every time.
我也试过以提升的权限运行代码,但无济于事.
I've also tried running the code with elevated privileges to no avail.
测试代码:
try
{
using (UdpClient client = new UdpClient(new IPEndPoint(IPAddress.Any, 123)))
{
Console.WriteLine("Port is open");
}
}
catch (SocketException error)
{
Console.WriteLine("Error:\n{0}", error.Message);
}
错误输出:
System.Net.Sockets.SocketException was unhandled
HResult=-2147467259
Message=An invalid argument was supplied
Source=System
ErrorCode=10022
NativeErrorCode=10022

请注意,如果我简单地调用 UdpClient client = new UdpClient();
As a note I get the same error if I simply call UdpClient client = new UdpClient();
推荐答案
问题是我的代码是从 Dropbox 文件夹执行的,并且由于某种原因导致了问题,即使 Dropbox 没有在系统上运行时间.如果我将代码库移到桌面并运行它,一切正常.
The issue was that my code was being executed from a Dropbox folder and for some reason that was causing the issues even if Dropbox wasn't running on the system at the time. If I moved the code base to the desktop and run it everything works.
我做了更多研究,发现问题不是 Dropbox 而是 Cloudfogger,如果我关闭 Cloudfogger 一切正常.
I did some more research and I've found that it is not Dropbox causing the issue but Cloudfogger, if I close Cloudfogger everything works.
这篇关于TcpClient 和 UdpClient 抛出错误的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
