winform程式壓縮檔上傳，伺服器端asp.net mvc進行接收解壓

標籤：ror   rman   tor   output   tip   ctf   open   access   添加   

期間編程沒什麼難度，唯一可能忽略導致結果失敗是asp.net  mvc配置

對於壓縮檔大的話，需要配置mvc的最大接收量：

  <system.web>    <httpRuntime maxRequestLength="2147483647" executionTimeout="3600" />    <!--允許上傳資料大小->  </system.web> <system.webServer>    <!--允許上傳檔案長度,單位位元組-->    <security>      　<requestFiltering>        <requestLimits maxAllowedContentLength="2147483647"/>      </requestFiltering>    </security> </system.webServer>

　　

 

winform中壓縮和上傳:

調用部分如下：

string proPath = Application.StartupPath + "\\temp\\product\\" + project.ProjectName;ZipFile(proPath,proPath + ".zip");//壓縮var uploadResult = Upload_Request(WebConfig.UploadUrl + "/Mobile/ReceiveProjectFile", proPath + ".zip",project.ProjectName + ".zip");//上傳if (uploadResult == 0){LoadingForm.CloseLoadingCircle();Notification t = new Notification("方案附件上傳失敗，請重試！", 3, FormAnimator.AnimationMethod.Slide, FormAnimator.AnimationDirection.Up, true, "error");t.Show();return;}File.Delete(proPath + ".zip");
