Char.ToLower Method (Char)

 

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

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

public static char ToLower(
	char 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.

using System;
using System.Globalization;  // for CultureInfo

public class ToLowerSample {
	public static void Main() {
		Console.WriteLine(Char.ToLower('A'));				// Output: "a"
	}
}
