当 PC 之间发生传输时，请告诉我如何解决此异常。
抛出异常：
(System.FormatException)
引发了 System.FormatException：“输入字符串的格式不正确。”
排队 ：
fileSize = Convert.ToInt32(Encoding.UTF8.GetString(byteFileSize));
我的整个代码：
private void Server()
{
FileStream fs = null;
BinaryWriter bw = null;
int fileSize = 0;
int bytesReceived = 0;
int bufferInt = Int32.Parse(textBoxBYTE2.Text);
byte[] bufferByte = new byte[bufferInt];
byte[] byteFileName = Encoding.UTF8.GetBytes("empty");
byte[] byteFileSize = Encoding.UTF8.GetBytes("empty");
string fileName = "";
int bytesTmp = 0;
try
{
IPEndPoint localEndPoint = new IPEndPoint(IPAddress.Parse(ServerIP), int.Parse(textBoxPORT1.Text));
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
socket.Bind(localEndPoint);
socket.Listen(10);
Socket listener = socket.Accept();
//[1] Принимаем имя
bytesTmp = listener.Receive(byteFileName);
fileName = Encoding.UTF8.GetString(byteFileName, 0, bytesTmp);
//[2] Принимаем размер
listener.Receive(byteFileSize);
fileSize = Convert.ToInt32(Encoding.UTF8.GetString(byteFileSize)); //Exception Thrown Here
fs = new FileStream(Path.Combine(textBoxPATH.Text, fileName), FileMode.CreateNew, FileAccess.Write);
bw = new BinaryWriter(fs);
//<!--
while (bytesReceived < fileSize)
{
if ((fileSize - bytesReceived) < bufferInt)
{
int bytes = (fileSize - bytesReceived);
byte[] buf = new byte[bytes];
bytes = listener.Receive(buf);
bw.Write(buf, 0, bytes);
bytesReceived = bytesReceived + bytes;
} else {
int bytes = listener.Receive(bufferByte);
bw.Write(bufferByte, 0, bytes);
bytesReceived = bytesReceived + bytes;
}
}
//-->
//Закрытие
bw.Close();
socket.Close();
listener.Close();
}
catch (Exception e)
{
System.Windows.Forms.MessageBox.Show("" + e, "Сервер сообщает");
}
}
