Strings.LCase Method (Char)

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

Returns a string or character converted to lowercase.

Namespace: Microsoft.VisualBasic
Assembly: Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

Syntax

'Declaration
Public Shared Function LCase ( _
    Value As Char _
) As Char

public static char LCase(
    char Value
)

Parameters

Value
Type: System.Char
Required. Any valid String or Char expression.

Return Value

Type: System.Char
Returns a string or character converted to lowercase.

Remarks

Only uppercase letters are converted to lowercase; all lowercase letters and nonletter characters remain unchanged.

This function uses the application's culture information when manipulating the string so that the case changes are appropriate for the locale in which the application is being used.

Security Note:
If your application makes security decisions based on the result of a comparison or case-change operation, then the operation should use the String.Compare method, and pass Ordinal or OrdinalIgnoreCase for the comparisonType argument.

Examples

This example uses the LCase function to return a lowercase version of a string.

' String to convert.
Dim UpperCase As String = "Hello World 1234"
' Returns "hello world 1234".
Dim LowerCase As String = LCase(UpperCase)
