Char.ToLowerInvariant Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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)

Syntax

'Declaration
Public Shared Function ToLowerInvariant ( _
    c As Char _
) As Char

public static char ToLowerInvariant(
    char c
)

Parameters

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.

Remarks

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).
