将这行代码从VB.NET转换为C＃？

Question

如何将以下代码行从VB.NET转换为C＃。

Dim bytes(tcpClient.ReceiveBufferSize) As Byte 

我从developerfusion网站下了一行，但它在我的程序中给了我错误的结果。

byte[] bytes = new byte[tcpClient.ReceiveBufferSize + 1]; 

这是我在Visual Basic中完整代码的一个示例。

Dim tcpClient As New System.Net.Sockets.TcpClient() 
TcpClient.Connect(txtIP.Text, txtPort.Text) 

Dim networkStream As NetworkStream = TcpClient.GetStream() 
If networkStream.CanWrite And networkStream.CanRead Then 

    Dim sendBytes As [Byte]() = Encoding.ASCII.GetBytes(txtSend.Text.Trim()) 

    networkStream.Write(sendBytes, 0, sendBytes.Length) 

    ' Read the NetworkStream into a byte buffer. 
    TcpClient.ReceiveBufferSize = 52428800 '50 MB 

    'Do I need to clean the buffer? 
    'Get the string back (response) 
    Dim bytes(tcpClient.ReceiveBufferSize) As Byte 
    networkStream.Read(bytes, 0, CInt(TcpClient.ReceiveBufferSize)) 

    ' Output the data received from the host to the console. 
    Dim returndata As String = Encoding.ASCII.GetString(bytes)

Visual Basic中指定绑定的阵列，而不是阵列（阵列索引0处开始）的长度的最大值，所以转换增加了一个额外的字节。然而，在您的代码中，正确的方法是：

byte[] bytes = new byte[tcpClient.ReceiveBufferSize]; 

如果您得到错误的结果，请告诉我们究竟发生了什么错误。也许这是代码的另一部分。

编辑：删除\ 0这样的：

byte[] bytes = new byte[tcpClient.ReceiveBufferSize]; 
int bytesRead = networkStream.Read(bytes, 0, tcpClient.ReceiveBufferSize); 
// Output the data received from the host to the console. 
string returndata = Encoding.ASCII.GetString(bytes,0,bytesRead); 

编辑：更妙的是读取数据包中的数据，所以你不需要保留一个大的缓冲前期：

byte[] bytes = new byte[4096]; //buffer 
int bytesRead = networkStream.Read(bytes, 0, bytes.Length); 
while(bytesRead>0) 
{ 
    // Output the data received from the host to the console. 
    string returndata = Encoding.ASCII.GetString(bytes,0,bytesRead); 
    Console.Write(returndata); 
    bytesRead = networkStream.Read(bytes, 0, bytes.Length); 
}
