Strings.UCase Method (String)

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

Returns a string or character containing the specified string converted to uppercase.

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

Syntax

'Declaration
Public Shared Function UCase ( _
    Value As String _
) As String

public static string UCase(
    string Value
)

Parameters

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

Return Value

Type: System.String
Returns a string or character containing the specified string converted to uppercase.

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.

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 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)
