Delete File

后台代码（非常简单）：
    protected void btnMaintainLog_Click(object sender, ImageClickEventArgs e)
    {
        if (!filePerson.HasFile)
        {
            UIHelper.Alert(this, "文档的路径不能为空");
            return;
        }
        if ("xls" != filePerson.FileName.Substring(filePerson.FileName.LastIndexOf(".") + 1))
        {
            UIHelper.Alert(this, "您上传的文档格式有误");
            return;
        }
        try
        {
            string path = Server.MapPath("~/AttacheFile/核心网室员工《卓越与进步》表扬档案记录榜080927.xls");
            if (File.Exists(path))
            {
                FileInfo fi = new FileInfo(path);
                if (fi.Attributes.ToString().IndexOf("ReadOnly") != -1)
                {
                    fi.Attributes = FileAttributes.Normal;
                }
                File.Delete(path);
                filePerson.SaveAs(path);
                UIHelper.Alert(this.Page, "上传修改员工档案成功！");
                return;
            }
        }
        catch(Exception ex)
        {
            UIHelper.Alert(this.Page, "上传出错！错误原因是" + ex.Message);
            return;
        }

    }

报错如上图所示,奇怪的是,路径字符串里的"/"全部去掉了，让人不解？(有谁知道的留言说声，谢谢)

错误原因：访问该文件的权限不够

解决办法：给该文件添加Everyone用户，并赋予所有权限。
