流不可讀 - 沒有處理，爲什麼這不起作用？

Question

我有以下代碼：

// Create POST data and convert it to a byte array. 
string postData = "name=t&description=tt"; 
byte[] byteArray = Encoding.UTF8.GetBytes(postData); 
// Set the ContentType property of the WebRequest. 
request.ContentType = "application/x-www-form-urlencoded"; 
// Set the ContentLength property of the WebRequest. 
request.ContentLength = byteArray.Length; 
// Get the request stream. 
using (StreamReader reader = new StreamReader(request.GetRequestStream())) 
{ 
    string s = reader.ReadToEnd(); 
} 

當流量擊中使用（.....）語句，我得到以下異常：

流未讀

我想將整個請求流讀入一個字符串，沒有任何東西被關閉，所以代碼應該工作？

Answer 1

您寫入請求流並從響應流中讀取。

string postData = "name=t&description=tt"; 
    byte[] byteArray = Encoding.UTF8.GetBytes(postData); 
    // Set the ContentType property of the WebRequest. 
    request.ContentType = "application/x-www-form-urlencoded"; 
    // Set the ContentLength property of the WebRequest. 
    request.ContentLength = byteArray.Length; 
    // Get the request stream. 

    var stream = request.GetRequestStream(); 
    stream.Write(byteArray, 0, byteArray.Length); 

Answer 2

流不可讀，因爲它打算寫入。看到這個鏈接的一個簡單的例子：
