Parameters

path

The file or directory for which to obtain access date and time information.

Returns

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

Exceptions

Type	Reason
ArgumentException	path is a zero-length string, contains only white space, or contains one or more implementation-specific invalid characters.
ArgumentNullException	path is null.
System.IO.IOException	The specified path was not found.
System.IO.PathTooLongException	The length of path or the absolute path information for path exceeds the system-defined maximum length.
System.Security.SecurityException	The caller does not have the required permission.
UnauthorizedAccessException	The caller does not have the required permission.

Remarks

Note:

This method may return an inaccurate value, because it uses native functions whose values may not be continuously updated by the operating system.

This method is identical to File.GetLastAccessTime(string).

If the directory described in the path parameter does not exist, this method returns 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC), adjusted to local time.

The path parameter is permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see Directory.GetCurrentDirectory.

The path parameter is not case-sensitive.
