VB.NET


Public Shared Function IsAsciiString(s As [String]) As Boolean
   Dim i As Integer
   For i = 0 To s.Length - 1
      Dim ch As Char = s(i)
      If ch < 0 Or ch > 127 Then
         Return False
      End If
   Next  
   Return True
End Function ’IsAsciiString

’In Page_Load
dim originalString  as string = 'a±' 
Response.Write (IsAsciiString(originalString))

	for (int i = 0; i < s.Length; i++)
	{

	}
