推荐答案

1.检查您的文件处于只读模式.如果是，请取消选中文件属性中的只读选项.

2.如果通过IIS运行，则必须授予iisusrs对该文件夹的权限.

转到您拥有xml的文件夹，然后单击属性"->安全"标签->编辑">添加".

位置->选择您的计算机名称
输入要选择的对象，然后输入iis_iusrs.
单击确定.
然后选中完全控制-允许"复选框

保存它.现在，iis用户将有权在该文件夹中写入任何文件

1. Check your file is in read only mode. If yes, uncheck the readonly options in the properties of the file.

2. If you are running through IIS, u have to give permission to iisusrs to that folder.

Go to the folder where you have your xml and click on properties->Security tab->Edit>Add.

Location->select ur machine name
Enter the object u neeed to select , enter iis_iusrs.
Click on ok.
Then select Full control-Allow checkbox

Save it.Now iis users will have permission to write any files inside that folder

这与您的代码本身无关.访问被拒绝. ASP.NET无法访问此目录.您只能使用网站根目录下的文件.要获取与站点的虚拟路径相对应的物理文件系统对象的正确路径，请使用System.Web.HttpServerUtility.MapPath:
http://msdn.microsoft.com/en-us/library/system. web.httpserverutility.mappath.aspx [ ^ ].

同样，像您一样使用XML也不是一个错误，但是这几乎没有道理.在大多数情况下，您可以使用序列化，尤其是 Data Contract ，这是持久保存任何对象或对象图的最健壮，不引人注目且易于使用的方式:
http://msdn.microsoft.com/en-us/library/ms973893.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/ms733127.aspx [ ^ ].

This is not related to your code per se. Access is denied. This directory is not accessible by ASP.NET. You can only work with files under the root directory of your site. To get a correct path to a physical file system object corresponding to a site''s virtual path, use System.Web.HttpServerUtility.MapPath:
http://msdn.microsoft.com/en-us/library/system.web.httpserverutility.mappath.aspx[^].

Also, working with XML like you do is not a mistake, but it rarely makes sense. In most cases, you can use serialization, in particular, Data Contract, which is the most robust, unobtrusive and easy to use way to persist any object or object graph:
http://msdn.microsoft.com/en-us/library/ms973893.aspx[^],
http://msdn.microsoft.com/en-us/library/ms733127.aspx[^].

asp.net功能为该功能提供了虚拟路径和物理路径检查，它将助您一臂之力

asp.net fuctinality provides virtual path and physical path check for that fuction it will hep you out
