HttpWebRequest以UTF-8編碼寫入內容時發生“Bytes to be written to the stream exceed the Content-Length bytes size specified.”錯誤

出錯代碼如下：

request.ContentLength = Encoding.UTF8.GetByteCount(content); var writer = new StreamWriter(request.GetRequestStream(), Encoding.UTF8); writer.Write(content); writer.Flush(); writer.Close();

原因是直接使用Encoding.UTF8，在StreamWriter中使用這個Encoding會在流的開頭寫入byte order mark. 解決方案是改用new UTF8Encoding(false)來構造不寫入byte order mark的Encoding.
