LCase Function (Visual Basic) 

Returns a string or character converted to lowercase.


Public Shared Function LCase(ByVal Value As Char) As Char
' -or-
Public Shared Function LCase(ByVal Value As String) As String

Parameters

Value

Required. Any valid String or Char expression.

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 noteSecurity Note

If your application makes security decisions based on the result of a comparison or case-change operation, then the operation should use the System.String.Compare(System.String,System.String,System.StringComparison) method, and pass Ordinal or OrdinalIgnoreCase for the comparisonType argument. For more information, see How Culture Affects Strings in Visual Basic.

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)
