Parameters

path

The path to search for an extension.

Returns

true if the characters that follow the last directory separator (\\ or /) or volume separator (:) in the path include a period (.) followed by one or more characters; otherwise, false.

Exceptions

Type	Reason
ArgumentException	path contains one or more implementation-specific invalid characters.

Remarks

Starting from the end of path, this method searches for a period (.) followed by at least one character. If this pattern is found before a Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar, or Path.VolumeSeparatorChar character is encountered, this method returns true.
