UdpClient C#客户端无法从服务器接收数据
我对我的UdpClient C#客户端无法从服务器接收数据,c#,C#,我对我的UDP客户端服务器应用程序有一个问题。 我在两者之间有联系。它们都互相发送数据。只有服务器从客户机接收数据,而不是相反,但服务器正在发送数据。我做错了什么 using System; using System.Globalization; using System.Net; using System.Net.Sockets; using System.Text; namespace PewPewGame { class Client { UdpClient udpClient;

首先:UDP不知道“连接”,所以您的第一行很混乱
然后您将使用UdpClient.Send(byte[],int)
方法发送数据,但这需要以前调用Connect(string,int)
或使用用于客户端的UdpClient构造函数:新建UdpClient(string,int)
我很确定您的空catch块(不要这样做,尤其是当某些东西没有按预期工作时不要这样做!)会根据[1]中的注释捕获并吞下SocketException:
此重载将数据报发送到在Connect方法中建立的远程主机,并返回发送的字节数。如果在调用此重载之前未调用Connect,Send方法将抛出SocketException。如果收到SocketException,请使用SocketException.ErrorCode获取特定的错误代码。获得此代码后,可以参考MSDN中的Windows Sockets版本2 API错误代码文档,以了解错误的详细说明
如果要将数据报发送到其他远程主机,则必须调用Connect方法并指定所需的远程主机。使用其他任一发送方法重载将数据报发送到广播地址
因此,在服务器代码中:
1) 拆下空的挡块
2) 使用接受客户端端点的函数-通过传入Receive(ref-IPEndPoint)
