winform程序壓縮文件上傳，服務器端asp.net mvc進行接收解壓
阿新 • • 發佈：2017-11-05
調用 第一個 iter return execution ucc inf each director
期間編程沒什麽難度，唯一可能忽略導致結果失敗是asp.net mvc配置
對於壓縮文件大的話，需要配置mvc的最大接收量：
<system.web>
<httpRuntime maxRequestLength="2147483647" executionTimeout="3600" /> <!--允許上傳數據大小->
</system.web>
<system.webServer>
<!--允許上傳文件長度,單位字節-->
<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");

strFile += Path.DirectorySeparatorChar;
ZipOutputStream s = new ZipOutputStream(File.Create(strZip));
s.SetLevel(6); // 0 - store only to 9 - means best compression
zip(strFile, s, strFile);
s.Finish();
s.Close();

if (strFile[strFile.Length - 1] != Path.DirectorySeparatorChar) strFile += Path.DirectorySeparatorChar;

string[] filenames = Directory.GetFileSystemEntries(strFile);
foreach (string file in filenames)
