从gprs接收数据为 。请帮忙解决这个问题。

本文介绍了从gprs接收数据为 。请帮忙解决这个问题。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在接收由GPRS设备发送的IP59.92.111.69的数据，但我没有收到正确的数据。我收到的数据只是问号（ ）。请帮我找到解决方案。 这是我的编码。 使用系统; 使用 System.Collections.Generic; 使用 System.Linq; 使用 System.Web; 使用 System.Web.UI; 使用 System.Web.UI.WebControls; 使用 System.Net.WebSockets; 使用 System.Net.Sockets; 使用 System.Net; 使用 System.Text; 使用 System.Threading.Tasks; 命名空间 TCP_IP_Client { public partial class client：System.Web.UI.Page { System.Net.Sockets.TcpClient clientsocket = new System.Net.Sockets.TcpClient（）; 受保护 void Page_Load（ object sender，EventArgs e） { clientsocket.Connect（ 59.92。 111.69， 8080 ）; Label1.Text = 服务器连接; } 受保护 void Button1_Click（ object sender，EventArgs e） { NetworkStream serverStream = clientsocket.GetStream（）; // byte [] outStream = System.Text.Encoding.ASCII.GetBytes（TextBox2.Text + $）; // serverStream.Write（outStream，0，outStream.Length） ; // serverStream.Flush（）; byte [] inStream = new byte [ 10025 ]; serverStream.Read（inStream， 0 ，（ int ）clientsocket.ReceiveBufferSize）; Response.Write（clientsocket.ReceiveBufferSize）; string returndata = System.Text.Encoding.UTF7.GetString（inStream）; // string returndata = System.Text.Encoding.UTF32.GetString（inStream）; // s.Length.ToString（）; msg（returndata） ; TextBox2.Text = ; TextBox2.Focus（）; } public void msg（ string mesg） { TextBox1.Text = Environment.NewLine + 和 + mesg; } } } 我尝试过： 我尝试过编码格式ASCII，UTF32，UTF7，UTF8和默认编码方法。解决方案 ）; // serverStream.Write（outStream，0， outStream.Length）; // serverStream.Flush（）; byte [] inStream = new byte [ 10025 ]; serverStream.Read（inStream， 0 ，（ int ）clientsocket.ReceiveBufferSize）; Response.Write（clientsocket.ReceiveBufferSize）; string returndata = System.T ext.Encoding.UTF7.GetString（插播广告）; // string returndata = System.Text.Encoding.UTF32.GetString（inStream）; // s.Length.ToString（）; msg（returndata） ; TextBox2.Text = ; TextBox2.Focus（）; } public void msg（ string mesg） { TextBox1.Text = Environment.NewLine + 和 + mesg; } } } 我尝试过： 我尝试过编码格式ASCII，UTF32，UTF7，UTF8和默认编码方法。 什么让你认为这是一个编码问题？ 这里的快速检查说没有返回真正的数据：数据缓冲区充满了空白。 所以检查你的IP地址，检查远程端，检查你的数据。 并且......看你的尺寸：默认的接收缓冲区大小比你分配的缓冲区大得多！ / BLOCKQUOTE> I am receiving data from the IP "59.92.111.69" which is sent by an GPRS device, but i am not getting correct data.
