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>
