asp.net 2.0的文件上传(突破上传限制4M)


            复制代码 代码如下:if (FileUpload1.HasFile) try { FileUpload1.SaveAs("d:\\luceneData\\" + FileUpload1.FileName); Label1.Text = "File name: " + FileUpload1.PostedFile.FileName + "<br>" + FileUpload1.PostedFile.ContentLength + " kb<br>" + "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 <httpRuntime executionTimeout="110" 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 += "<u>File #" + (i + 1) + "</u><br>"; Label1.Text += "File Content Type: " + userPostedFile.ContentType + "<br>"; Label1.Text += "File Size: " + userPostedFile.ContentLength + "kb<br>"; Label1.Text += "File Name: " + userPostedFile.FileName + "<br>"; userPostedFile.SaveAs(filepath + "\\" + System.IO.Path.GetFileName(userPostedFile.FileName)); Label1.Text += "Location where saved: " + filepath + "\\" + System.IO.Path.GetFileName(userPostedFile.FileName) + "<p>"; } } catch (Exception Ex) { Label1.Text += "Error: <br>" + Ex.Message; } } }
