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)

Syntax

Visual Basic (Declaration)

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

Visual Basic (Usage)

Dim c As Char
Dim returnValue As Char

returnValue = Char.ToLowerInvariant(c)

public static char ToLowerInvariant(
    char c
)

Visual C++

public:
static wchar_t ToLowerInvariant(
    wchar_t c
)

JScript

public static function ToLowerInvariant(
    c : char
) : char

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.

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).

Use String..::.ToLowerInvariant to convert a string to lowercase.
