Strings.LCase Method (Char)
Returns a string or character converted to lowercase.
Assembly: Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)
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.
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. For more information, see How Culture Affects Strings in Visual Basic.
