Required. Any valid String or Char expression.
Returns
A string or character containing the specified string converted to uppercase.
Examples
This example uses the UCase function to return an uppercase version of a string.
' String to convert.
Dim lowerCase As String = "Hello World 1234"
' Returns "HELLO WORLD 1234".
Dim upperCase As String = UCase(lowerCase)
Remarks
Only lowercase letters are converted to uppercase; all uppercase 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.
Important
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.
