將這行代碼從VB.NET轉換爲C＃？

Question

如何將以下代碼行從VB.NET轉換爲C＃。

Dim bytes(tcpClient.ReceiveBufferSize) As Byte 

我從developerfusion網站下了一行，但它在我的程序中給了我錯誤的結果。

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

這是我在Visual Basic中完整代碼的一個示例。

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中指定綁定的陣列，而不是陣列（陣列索引0處開始）的長度的最大值，所以轉換增加了一個額外的字節。然而，在您的代碼中，正確的方法是：

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

如果您得到錯誤的結果，請告訴我們究竟發生了什麼錯誤。也許這是代碼的另一部分。

編輯：刪除\ 0這樣的：

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); 

編輯：更妙的是讀取數據包中的數據，所以你不需要保留一個大的緩衝前期：

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); 
}
