我必須要一個名爲uploadFile的web服務方法，該方法獲取一個參數爲base64str並將其作爲文件記錄到指定的地址中。 但是，我有一個問題。該方法不允許上傳超過350 KB的文件。否則，我可以上傳小於300 KB的文件，例如zip，jpg，txt。另外， 當我嘗試上傳超過350 KB的文件時，一個進程可以在服務器上持續工作。文件發佈問題 - ASP.Net
過程：
Image Name : w3wp.exe, UserName : ASP.Net v4.0, CPU : 50, Description : IIS Worker Process
有時服務器CPU前進到100％
代碼：
* encodedFile = Base64Str as format
string postString = string.Format("userName={0}&userVendor={1}&vendorKey={2}&base64FileStr={3}&guid={4}&fileName={5}", "kadi", "şifre", "key", encodedFile, guid, strFilename);
string localHttpPostUrl = userGatewayAddress + "uploadFile";
ASCIIEncoding encoding = new ASCIIEncoding();
Stream newStream = null;
HttpWebResponse response = null;
Stream streamResponse = null;
StreamReader streamRead = null;
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(localHttpPostUrl);
request.ContentType = "application/x-www-form-urlencoded";
request.Method = "POST";
byte[] buffer = Encoding.UTF8.GetBytes(postString);
request.ContentLength = buffer.Length;
newStream = request.GetRequestStream();
newStream.Write(buffer, 0, buffer.Length);
newStream.Close();
response = (HttpWebResponse)request.GetResponse();
streamResponse = response.GetResponseStream();
streamRead = new StreamReader(streamResponse);
Char[] readBuffer = new Char[256];
ret = string.Empty;
int totalCharCount = 0;
int count = streamRead.Read(readBuffer, 0, 256);
while (count > 0)
{
totalCharCount += count;
ret += new String(readBuffer);
count = streamRead.Read(readBuffer, 0, 256);
}
ret = ret.Substring(0, totalCharCount);
return ret;
}
catch (Exception x)
{
return x.Message;
}
