示例1: AsyncUpload
public AsyncUpload(HttpWorkerRequest wRquest)
{
if (wRquest == null) throw new ArgumentNullException("wRquest");
this.uploadProcess = new UploadProcess(delegate(float f) { });
workerRequest = wRquest;
//當前讀到的流長度
this.preLen = workerRequest.GetPreloadedEntityBodyLength();
//請求流的總長度
this.totLen = workerRequest.GetTotalEntityBodyLength();
//內容分隔符 如: -----------------------------152733254716788
