Directory.GetCreationTime Method

Gets the creation date and time of a directory.

[Visual Basic]
Public Shared Function GetCreationTime( _
   ByVal path As String _
) As DateTime
[C#]
public static DateTime GetCreationTime(
 string path
);
[C++]
public: static DateTime GetCreationTime(
 String* path
);
[JScript]
public static function GetCreationTime(
   path : String
) : DateTime;

Parameters

path
The path of the directory.

Return Value

A DateTime structure set to the creation date and time for the specified directory. This value is expressed in local time.

Exceptions

Exception Type Condition
IOException The specified path was not found.
UnauthorizedAccessException The caller does not have the required permission.
ArgumentException path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.
ArgumentNullException path is a null reference (Nothing in Visual Basic).
PathTooLongException The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.

Remarks

This method is equivalent to File.GetCreationTime.

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 GetCurrentDirectory.

The path parameter is not case-sensitive.
