Question

嗨，我有以下代码发送数据，但作为回报，我收到服务器错误，错误代码为500，文件为没有通过请求发送

谁能告诉我我在做什么错

   FileStream rdr = new FileStream("C:/Users/AR485UY/Desktop/Test1.pdf", FileMode.Open)

   HttpWebRequest req = (HttpWebRequest)WebRequest.Create("url" );

string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");

req.Method = "POST"; 

req.ContentLength = rdr.Length;

req.ContentType = "multipart/form-data; boundary=" +boundary;

req.AllowWriteStreamBuffering = true;

Stream reqStream = req.GetRequestStream();

byte[] inData = new byte[rdr.Length];

int len = Convert.ToInt32(rdr.Length);

int bytesRead = rdr.Read(inData, 0, len);

reqStream.Write(inData, 0, len);

rdr.Close();

req.GetResponse();

reqStream.Close();

HTTP 500 Internal Server Error服务器错误响应代码表示服务器遇到意外状况，阻止其满足请求。

如果它永远不起作用：最有可能必须验证您的服务器端api，脚本，日志，事件，诊断跟踪，文件大小限制。

也可以尝试使用c＃的另一种方法：

try
{
    using(WebClient client = new WebClient())
   {
    string myFile = @"C:/Users/AR485UY/Desktop/Test1.pdf";
    client.Credentials = CredentialCache.DefaultCredentials;
    client.UploadFile(url, "POST", myFile);

    }
}
catch (Exception err)
{
    MessageBox.Show(err.Message);
}
