system.io.file.exists不在mvc4中工作

Question

我正在从kendo上传控件中删除图片。

这是我的代码

  public ActionResult Remove(string[] fileNames)
    {

        if (fileNames != null)
        {
            foreach (var fullName in fileNames)
            {
                var fileName = Path.GetFileName(fullName);
                var physicalPath = Server.MapPath(Path.Combine(("~/AssetAttachments"),fileName));

                if (System.IO.File.Exists(physicalPath))
                {
                     System.IO.File.Delete(physicalPath);
                }
            }
        }
        return Content("");
    }

物理路径是E：\ karthik相关\ JPL \ Dev \ Src \ AssetTrackingSystem \ AssetTrackingSystem \ AssetAttachments \ Attach3.jpg

即使文件和目录可用

  if (System.IO.File.Exists(physicalPath))

正在返回false并且已经过时了。

我们将不胜感激。

Answer 1

试试这个：

foreach (var fullName in fileNames)
{
     var physicalPath = System.IO.Path.Combine(HttpContext.Current.Server.MapPath("~/AssetAttachments"), fullName);

     if (System.IO.File.Exists(physicalPath))
     {
         System.IO.File.Delete(physicalPath);
     }
}

Answer 2

试试这个，

FileInfo fi = new FileInfo(Path.Combine(("~/AssetAttachments"),fileName));
 if (fi.Exists)
 {
   fi.Delete();
 }
