ASP.NET MVC上传图片并把图片保存在本地
一、上传单张图片
前端
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
@using (Html.BeginForm("addFile", "First", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<input type="file" name="myFile" />
<input type="submit" />
}
</div>
</body>
</html>后台
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace 上传图片并把图片保存在本地.Controllers
{
public class FirstController : Controller
{
public static string toImagePath = @"D:\";
// GET: First
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult addFile()
{
try
{
HttpPostedFileBase file = Request.Files["myFile"];
string FileName = DateTime.Now.ToString("yyyyMMddhhmmss");
if (file.ContentType == "image/jpeg" || file.ContentType == "image/png")
{
if (int.Parse(file.ContentLength.ToString()) > ((1024 * 1024) * 5))
{
//图片大小不能大于5M;
return Redirect("/First/Index");
}
else
{
//图片存储路径
file.SaveAs(toImagePath + FileName + ".jpg");
}
}
return Redirect("/First/Index");
}
catch (Exception)
{
throw;
}
}
}
}二、上传多张图片
前端
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
@using (Html.BeginForm("addFile", "First", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<input type="file" multiple="multiple" name="myFile" />
<input type="submit" />
}
</div>
</body>
</html>后台
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace 上传图片并保存在本地.Controllers
{
public class FirstController : Controller
{
public static string toImagePath = @"D:\";
// GET: First
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult addFile(IEnumerable<HttpPostedFileBase> myFile)
{
try
{
foreach (var file in myFile)
{
if (file != null && file.ContentLength > 0)
{
if (file.ContentType == "image/jpeg" || file.ContentType == "image/png")
{
if (int.Parse(file.ContentLength.ToString()) > (1024 * 1024) * 5)
{
//图片大小不能大于5M;
continue;
}
else
{
string FileName = DateTime.Now.ToString("yyyyMMddhhmmss");
//图片存储路径
file.SaveAs(toImagePath + FileName + ".jpg");
}
}
}
}
return Redirect("/First/Index");
}
catch (Exception)
{
throw;
}
}
}
}检查是否要创建上传文件夹
private bool CreateFolderIfNeeded(string path)
{
bool result = true;
if (!Directory.Exists(path))
{
try
{
Directory.CreateDirectory(path);
return result;
}
catch (Exception)
{
result = false;
}
}
return result;
}如何把图片存储到当前项目某个文件夹
string urlPath = Server.MapPath(toImagePath);// 读取到当前虚拟目录的根目录
