MVC图片上传 (CJ)

视图
@using (Html.BeginForm("HeroAdd", "Hero", FormMethod.Post, new { enctype = "multipart/form-data" }))
        { 
            <table>
                <tr>
                    <td>头像:</td>
                    <td><input type="file" name="Hicon" id='File1' /></td>
                </tr>
                <tr>
                    <td>名称:</td>
                    <td>@Html.TextBoxFor(a => a.HName)</td>
                </tr>            
                <tr>
                    <td>阵营:</td>
                    <td>@Html.DropDownList("CampID")</td>
                </tr>
                <tr>
                    <td></td>
                    <td><input type="submit" value="添加" onclick='fileclick()'/></td>
                </tr>
            </table>
        }
必须添加new { enctype = "multipart/form-data" }


后台代码     HttpPostedFileBase 接收图片
public ActionResult HeroAdd(Hero Add, HttpPostedFileBase Hicon)
        {
            if (Hicon != null)
            {
                string imgName = DateTime.Now.ToString("yyyymmddss") + Hicon.FileName.Substring(Hicon.FileName.LastIndexOf('.'));//根据日期修改图片名称
                Hicon.SaveAs(Server.MapPath("/image/" + imgName));//将图片上传到image文件夹中
                Add.Hicon = "/image/" + imgName;  //存储数据库路径
            }
        }




//使用js判断图片类型
       function fileclick(){
       var f=document.getElementById("File1").value;
        if(f=="")
        { alert("请上传图片");return false;}
        else
        {
        if(!/\.(gif|jpg|jpeg|png|GIF|JPG|PNG)$/.test(f))
        {
          alert("图片类型必须是.gif,jpeg,jpg,png中的一种")
          return false;
        }
        }
}
