Char.ToUpperInvariant Method

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

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

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Syntax

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

public static char ToUpperInvariant(
    char c
)

Parameters

  • c
    Type: System.Char
    The Unicode character to convert.

Return Value

Type: System.Char
The uppercase equivalent of the c parameter, or the unchanged value of c, if c is already uppercase 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, use the ToUpperInvariant method. The ToUpperInvariant method is equivalent to ToUpper(Char, CultureInfo.InvariantCulture).

Use String.ToUpperInvariant to convert a string to uppercase.
