Question

我有以下代码：

 // 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();
 }

当流程点击using（.....）语句时，我得到以下异常：

Stream无法读取

我想将整个请求流读入字符串，没有关闭，所以代码应该有效吗？

Answer 1

您写入请求流并从响应流中读取。

    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 );

流不可读，因为它打算写入。请参阅此链接以获取一个简单示例：

Stream无法读取 - 没有任何处理，为什么这不起作用？
