Asp.Net上传文件并配置可上传大文件的方法_基础应用_

//上传文件保存路径 string savePath = Server.MapPath("UploadFiles") + "\\"; //提供对客户端上载文件的访问 HttpFileCollection uploadFiles = System.Web.HttpContext.Current.Request.Files; for (int i = 0; i < uploadFiles.Count; i++) { System.Web.HttpPostedFile postedFile = uploadFiles[i]; string fileName = postedFile.FileName;//完整的路径 fileName = System.IO.Path.GetFileName(postedFile.FileName); //获取到名称 string fileExtension = System.IO.Path.GetExtension(fileName);//文件的扩展名称 string type = fileName.Substring(fileName.LastIndexOf(".") + 1); //类型 if (uploadFiles[i].ContentLength > 0) uploadFiles[i].SaveAs(savePath + fileName); }

protected void btnsave_Click(object sender, EventArgs e) { StringBuilder sb = new StringBuilder(); if (FileUpload1.HasFile) { try { sb.AppendFormat(" Uploading file: {0}", FileUpload1.FileName); //saving the file FileUpload1.SaveAs("" + FileUpload1.FileName); //Showing the file information sb.AppendFormat("
 Save As: {0}", FileUpload1.PostedFile.FileName); sb.AppendFormat("
 File type: {0}", FileUpload1.PostedFile.ContentType); sb.AppendFormat("
 File length: {0}", FileUpload1.PostedFile.ContentLength); sb.AppendFormat("
 File name: {0}", FileUpload1.PostedFile.FileName); } catch (Exception ex) { sb.Append("
 Error 
"); sb.AppendFormat("Unable to save file 
 {0}", ex.Message); } } else { lblmessage.Text = sb.ToString(); } }
