Parameters

path

A string containing the name of the file or directory for which to obtain access date and time information.

Returns

A DateTime structure set to the date and time the specified file or directory was last accessed. This value is expressed in local time.

Platforms that do not support this feature return DateTime.MinValue.

Permissions

Type	Reason
System.Security.Permissions.FileIOPermission	Requires permission to read the specified file or directory. See System.Security.Permissions.FileIOPermissionAccess.Read.

Exceptions

ArgumentNullException	path is null.

Remarks

This method is equivalent to File.GetLastAccessTime(string) (path).

The path argument is permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory.

Note: To obtain the current working directory, see Directory.GetCurrentDirectory.
