●在asp.net2.0中,上传文件时变的...... 在asp.net 2.0中,上传文件时变的比较方便了,因为有了fileupload控件,使用十分简单, if (FileUpload1.HasFile) try { FileUpload1.SaveAs("d:\\luceneData\\" + FileUpload1.FileName); Label1.Text = "File name: " + FileUpload1.PostedFile.FileName + " " + FileUpload1.PostedFile.ContentLength + " kb " + "Content type: " + FileUpload1.PostedFile.ContentType; } catch (Exception ex) { Label1.Text = "ERROR: " + ex.Message.ToString(); } else { Label1.Text = "You have not specified a file."; } 还可以在web.config文件中,突破默认上传限制的4MB,比如 maxRequestLength="11000" requestLengthDiskThreshold="80" useFullyQualifiedRedirectUrl="false" minFreeThreads="8" minLocalRequestFreeThreads="4" appRequestQueueLimit="5000" enableKernelOutputCache="true" enableVersionHeader="true" requireRootedSaveAsPath="true" enable="true" shutdownTimeout="90" delayNotificationTimeout="5" waitChangeNotification="0" maxWaitChangeNotification="0" enableHeaderChecking="true" sendCacheControlHeader="true" apartmentThreading="false" /> 设置maxRequestLenth属性,这里为11000KB,即11MB。 而对于多文件上传,也很简单,比如一个例子 string filepath = "d:\\luceneData\\"; HttpFileCollection uploadedFiles = Request.Files; for (int i = 0; i < uploadedFiles.Count; i++) { HttpPostedFile userPostedFile = uploadedFiles[i]; try { if (userPostedFile.ContentLength > 0) { Label1.Text += "File #" + (i + 1) + " "; Label1.Text += "File Content Type: " + userPostedFile.ContentType + " "; Label1.Text += "File Size: " + userPostedFile.ContentLength + "kb "; Label1.Text += "File Name: " + userPostedFile.FileName + " "; userPostedFile.SaveAs(filepath + "\\" + System.IO.Path.GetFileName(userPostedFile.FileName)); Label1.Text += "Location where saved: " + filepath + "\\" + System.IO.Path.GetFileName(userPostedFile.FileName) + " "; |
