的TcpClient异常的新实例 [英] New Instance of TCPClient Exception

问题描述

我前几天问这个类似的问题。在这一点上，我试图用插座。目前，我使用的TcpClient做肮脏的插座为我工作。我使用Windows 7和视觉工作室2013专业版

原件和电流项目概况：

我需要创建一个应用程序（使用C＃的WinForms），允许用户连接到设备（硬件设备，将参数/命令发送）通过WiFi（WiFi是最终目标，但我目前解决任何连接），然后将邮件发送到该装置。我知道一些C＃和一些插座/ IP的东西，但不使用插座/ IP C＃。该方案的可视化，图形用户界面一边是不是我与挣扎。我似乎无法得到的TcpClient启动和运行，并进行任何真正的联系。我不断收到一个无效的参数提供异常。

在这个问题上的任何提示或C＃网络/的TcpClient /等帮助。 。欢迎

我试图创建一个新的TcpClient每一没有成功以下几种方式：

 的TcpClient的TcpClient =新的TcpClient（）; 
的TcpClient的TcpClient =新的TcpClient（家庭）; //家庭是一个创造AddressFamily 
的TcpClient的TcpClient =新的TcpClient（端ClientIPAddress，clientPortNumber）; 
的TcpClient的TcpClient =新的TcpClient（remoteEP）; // remoteEP是由我建立了一个远程端点
的TcpClient的TcpClient =新的TcpClient（localEP）; // localEP是当地的终点
  

每个这些是的TcpClient类中构造函数之一。每一个这些给了我以下异常：
一个无效的参数提供

堆栈跟踪：

在System.Net.Sockets.Socket..ctor（AddressFamily addressFamily，socketType socketType，ProtocolType protocolType）\r\\\
在System.Net.Sockets.TcpClient .initialize（）\r\\\
在System.Net.Sockets.TcpClient..ctor（AddressFamily家族）\r\\\
在System.Net.Sockets.TcpClient..ctor（）\r\\\
在ConnectLite.ConnectLite.MakeConnection（）在H：\Howard\Projects\ConnectLite\ConnectLite\Form1.cs：线​​120

我拥有所有必要的进口和usings的。

这问题时，我尝试运行在不同的计算机上的应用程序变得奇怪。在单独的计算机，无论是运行应用程序，而不从调试文件视觉工作室，或者使用视觉工作室2013年不同的计算机上运行它，应用程序需要我进一步比异常，异常抛出永远。

我只是尝试使用的TcpClient做一些简单的信息发送。该的TcpClient，但是，阻止我这样做。

当我使用套接字被，它是创造一个新的socket时抛出同样的异常。

 插座ClientSocket的= 
新的Socket（AddressFamily.InterNetwork，SocketType.Stream，ProtocolType.Tcp）; 
  

做任何你对此事有何看法？

要简化，我已经把代码相关的块，放入一个控制台应用程序，从而很容易读

与发行代码简单的块：

 使用系统; 
使用System.Collections.Generic; 
使用System.Linq的;使用System.Net 
;使用的System.Net.Sockets 
; 
使用System.Text;使用System.Threading.Tasks 
; 
 
命名空间ConsoleTestConnectLite 
 {
类节目
 {
静态无效的主要（字串[] args）
 {
试
 {
的TcpClient的TcpClient =新的TcpClient（）; 
} 
赶上（SocketException E）
 {
 Console.WriteLine（e.Message）; 
 Console.WriteLine（错误：+ e.StackTrace）; 
 Console.WriteLine（e.Message +错误代码：+ e.ErrorCode.ToString（））; 
} 
} 
} 
} 
  

控制台输出：

 一个无效的参数提供

按任意键继续。 。 。 
  

解决方案

您会得到这个错误，如果你的代码被放置在网络驱动器。移动你的代码到本地机器就能解决问题。

I asked a similar question to this a few days ago. At that point, I was trying to use sockets. Currently, I am using TCPClient to do the dirty socket work for me. I am using Windows 7 and Visual studios 2013 Professional.

Original and Current Project Outline:

I need to create an application (WinForms using C#) that allows the user to connect to a device (a piece of hardware that will be sent arguments/commands) via wifi (wifi is end goal but I am settling at the moment for any connection) and then send messages to said device. I know some C# and some sockets/IP stuff, but not sockets/IP using C#. The visual, GUI side of the program is not what I am struggling with. I cannot seem to get the TCPClient up and running and make any real connection. I keep getting the "An Invalid Argument was Supplied" exception.

Any tips on this particular issue or help with C# networking/TCPClient/etc. are welcome.

I have tried to create a new TcpClient each of the following ways without success:

TcpClient tcpClient = new TcpClient();
TcpClient tcpClient = new TcpClient(family); // family is a created AddressFamily
TcpClient tcpClient = new TcpClient(clientIPAddress, clientPortNumber);
TcpClient tcpClient = new TcpClient(remoteEP); // remoteEP is a remote end point created by me
TcpClient tcpClient = new TcpClient(localEP); // localEP is a local end point

Each of these is one of the constructors within the TCPClient class. Each of these gives me the following exception: An Invalid Argument was Supplied

Stack Trace:

at System.Net.Sockets.Socket..ctor(AddressFamily addressFamily, SocketType socketType, ProtocolType protocolType)\r\n at System.Net.Sockets.TcpClient.initialize()\r\n at System.Net.Sockets.TcpClient..ctor(AddressFamily family)\r\n at System.Net.Sockets.TcpClient..ctor()\r\n at ConnectLite.ConnectLite.MakeConnection() in h:\Howard\Projects\ConnectLite\ConnectLite\Form1.cs:line 120

I do have all of the necessary imports and usings.

This problem gets strange when I try to run the application on a different computer. On separate computers, whether it be running the application without Visual Studios from the debug file, or running it on a different computer using Visual Studios 2013, the application takes me further than the exception and the exception is never thrown.

I am simply trying to use TCPClient to do some simple message sending. The TCPClient, however, is preventing me from doing that.

When I had been using sockets, it was throwing the same exception when creating a new socket.

Socket clientSocket =
new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

Do any of you have any insights on this matter?

To simplify, I have put the pertinent pieces of code into a console app so as to be easily read.

Simple block of code with issue:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleTestConnectLite
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                TcpClient tcpClient = new TcpClient();
            }
            catch (SocketException e)
            {
                Console.WriteLine(e.Message);
                Console.WriteLine("Error: " + e.StackTrace);
                Console.WriteLine(e.Message + ". Error Code: " + e.ErrorCode.ToString());
            }
        }
    }
}

Console Output:

An invalid argument was supplied
Error:    at System.Net.Sockets.Socket..ctor(AddressFamily addressFamily, Socket
Type socketType, ProtocolType protocolType)
   at System.Net.Sockets.TcpClient.initialize()
   at System.Net.Sockets.TcpClient..ctor(AddressFamily family)
   at System.Net.Sockets.TcpClient..ctor()
   at ConsoleTestConnectLite.Program.Main(String[] args) in h:\Howard\Projects\ConsoleTestConnectLite\ConsoleTestConnectLite\Program.cs:line 17
An invalid argument was supplied. Error Code: 10022
Press any key to continue . . .

解决方案

You will get that error if your codes are placed on a network drive. Moving your code to local machine will solve the problem.
