我有一个带有实体框架的mvc4应用程序.
我想删除一个文件,但每次都说:
mscorlib.dll中出现"System.UnauthorizedAccessException"类型的异常,但未在用户代码中处理
附加信息:访问路径'G:\ Mijn Documents\My Web Sites\Lolabikes - Copy\C#\ ContosoUniversity\Images \'被拒绝.
通过这一行:System.IO.File.Delete(path);
这是方法:
public ActionResult DeleteFiles(int id)
{
//var fileName = Path.GetFileName(id.FileName);
var DirSeparator = Path.DirectorySeparatorChar;
var path = Server.MapPath("~\\Images" + DirSeparator);// + fileName.Replace('+', '_')));
var file = db.lolabikerPhotos.Find(id);
System.IO.File.Delete(path);
db.SaveChanges();
return Redirect(Url.Action("Edit", "Account") + "#tabs-3");
}
我只是在visual studio中运行应用程序,如下所示: http://localhost:41787/Account/Edit?UserId=hallo
我已经完成了以下事情:
完全访问地图,我将网络服务添加到地图并完全控制.但似乎没有任何效果.我正在使用Windows 7.我以管理员身份运行visual studio 2013
我也看到了这个:
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has …c# windows entity-framework asp.net-mvc-4 visual-studio-2013
我有这个:
模型:
public string Picture { get; set; }
[Column(TypeName = "image")]
public byte[] Image { get; set; }
[Display(Name = "Display profile Image")]
public bool DisplayItem { get; set; }
视图:
<div class="editor-label">
@Html.LabelFor(model => model.DisplayItem)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.DisplayItem)
@Html.ValidationMessageFor(model => model.DisplayItem)
</div>
<div class="editor-label">
@Html.LabelFor(m => m.Image)
</div>
<input type="file" name="file"/>
和控制器:
public ActionResult Edit(string UserId)
{
string username = User.Identity.Name;
// Fetch the userprofile
UserProfile user = db.userProfiles.FirstOrDefault(u => u.UserName.Equals(username));
// Construct the viewmodel …我有这个:_Layout.cshtml
