Char::ToLower Method (Char)

.NET Framework (current version)
 

Converts the value of a Unicode character to its lowercase equivalent.

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

C#
C++
F#
VB
Copy 
public:
static wchar_t ToLower(
	wchar_t c
)

Parameters

c
Type: System::Char

The Unicode character to convert.

Return Value

Type: System::Char

The lowercase equivalent of c, or the unchanged value of c, if c is already lowercase or not alphabetic.

Casing rules are obtained from the current culture.

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

Notes to Callers:

As explained in Best Practices for Using Strings in the .NET Framework, we recommend that you avoid calling character-casing and string-casing methods that substitute default values. Instead, you should call methods that require parameters to be explicitly specified. To convert a character to lowercase by using the casing conventions of the current culture, call the ToLower(Char, CultureInfo^) method overload with a value of CultureInfo::CurrentCulture for its culture parameter.

The following example demonstrates ToLower.

C#
C++
VB
Copy 
using namespace System;
using namespace System::Globalization;

// for CultureInfo
void main()
{
   Console::WriteLine( Char::ToLower( 'A' ) ); // Output: "a"
}
