Char.ToLowerInvariant Method

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)

public static char ToLowerInvariant (
	char c
)
public static char ToLowerInvariant (
	char c
)
public static function ToLowerInvariant (
	c : char
) : char
Not applicable.

Parameters

c

A Unicode character.

Return Value

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).

Use String.ToLowerInvariant to convert a string to lowercase.
