Question

我有以下问题，我尝试从TCP / IP套接字接收原始HEX值并将其写在txt文件中，只有我在将此原始HEX数据转换为UTF-8字符串时遇到一些问题。我使用以下方法：

TcpClient client = new TcpClient("192.168.200.91", 2101);
NetworkStream netStream = client.GetStream();
byte[] bytes = new byte[client.ReceiveBufferSize];
netStream.Read(bytes, 0, (int)client.ReceiveBufferSize);

string returndata = Encoding.UTF8.GetString(bytes);

using (var writer = new StreamWriter(@"C:\Users\ -\Documents\test.txt", false, Encoding.UTF8))
{
    writer.WriteLine(returndata);
}

返回：*þý% ˆ ê‡… ÿ Œ7ºe B %û

如何成功读取原始HEX数据并将其转换为可读字符串？

使用BitConverter：

TcpClient client = new TcpClient("192.168.200.91", 2101);
NetworkStream netStream = client.GetStream();
byte[] bytes = new byte[client.ReceiveBufferSize];
int bytesRead = netStream.Read(bytes, 0, (int)client.ReceiveBufferSize);

string returndata = BitConverter.ToString(bytes, 0, bytesRead).Replace("-", "")

using (var writer = new StreamWriter(@"C:\Users\ -\Documents\test.txt", false, Encoding.UTF8))
{
    writer.WriteLine(returndata);
}
