通过套接字接收原始十六进制并转换为字符串

Question

我有以下问题，我尝试从TCP/IP套接字接收原始十六进制值并将它们写入一个txt文件，只有我有一些问题转换此原始十六进制数据转换为UTF-8字符串。我使用下面的方法：

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); 
} 

这将返回：*þý% ˆ ꇅ ÿ Œ7ºe B %û

如何成功地读取原始数据HEX并转换成可读的字符串呢？

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); 
}
