上传文件是一项基本功能，一定要了解的。先来看一下使用ASP.NET MVC实现简单的上传。
一、简单的例子
Controller的例子
public ActionResult UploadDemo() { return View(); } public ActionResult FileUpload() { HttpPostedFileBase file = Request.Files["file"]; if (file != null) { string filePath = Path.Combine(HttpContext.Server.MapPath("../Uploads"), Path.GetFileName(file.FileName)); file.SaveAs(filePath); Response.Write("<script>alert(‘上传成功‘);location.href=‘/Index/UploadDemo‘ </script>"); } else { Response.Write("<script>alert(‘上传失败‘);location.href=‘/Index/UploadDemo‘ </script>"); } return null; }
对应的View视图
@{ Layout = null; } <!DOCTYPE html> <html> <head> <title>UploadDemo</title> </head> <body> <div> <h2> 上传例子</h2> @using (Html.BeginForm("FileUpload", "Index", FormMethod.Post, new { enctype = "multipart/form-data" })) { <input type="file" name="file" /> <input type="submit" value="uploadFile" /> } </div> </body> </html>
