Make sure the ASP user has permissions to this folder. By default this user is not given access to much of the harddrive..
确保 ASP 用户对该文件夹具有权限。默认情况下，此用户无法访问大部分硬盘驱动器。

In order to delete a file you must ensure that the account has sufficient permissions. In general ASP.NET applications run under limited permission account such as Network Service. For example if your application runs under IIS 6 you could go to the Administration Console and set a custom account in the application pool properties:
为了删除文件，您必须确保该帐户具有足够的权限。通常 ASP.NET 应用程序在有限权限帐户下运行，例如Network Service. 例如，如果您的应用程序在 IIS 6 下运行，您可以转到管理控制台并在应用程序池属性中设置一个自定义帐户：
alt text http://i.msdn.microsoft.com/Bb969101.SharePoint_SQL_TshootingFig3%28en-US,SQL.90%29.jpg
替代文字 http://i.msdn.microsoft.com/Bb969101.SharePoint_SQL_TshootingFig3%28en-US,SQL.90%29.jpg
You need to ensure that the account is member of the IIS_WPGgroup.
您需要确保该帐户是该IIS_WPG组的成员。

public void DeleteFileFromFolder(string StrFilename)
{
string strPhysicalFolder = Server.MapPath("..\");
string strFileFullPath = strPhysicalFolder + StrFilename;
if (IO.File.Exists(strFileFullPath)) {
IO.File.Delete(strFileFullPath);
}
}
