Char.ToLowerInvariant Method

May 02, 2013

Converts the value of a Unicode character to its lowercase equivalent using the casing rules of the invariant culture.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
C#
VB
Copy 
public static char ToLowerInvariant(
	char c
)

Parameters

c
Type: System.Char
A Unicode character.

Return Value

Type: System.Char
The lowercase equivalent of the c parameter, or the unchanged value of c, if c is already lowercase or not alphabetic.

If your application is unaffected by the current culture and depends on the case of a character changing in a predictable way, then use the ToLowerInvariant method. The ToLowerInvariant method is equivalent to ToLower(Char, CultureInfo.InvariantCulture).
