Hi!

How can I check which chars in String are UpperCase chars?

I mean for example string "aAbBc" has second and fourth character uppercase
characters, so I want to get this information somehow. I'm using VB .NET
2003, but understand C# also quite well.

Thanks in advance!

like this :

Dim c As Char

For Each c In TextBox1.Text
If UCase(c) = c Then
MsgBox(c & " is uppercase")
Else
MsgBox(c & " is lowercase")
End If
Next

then i suppose instead of "MsgBox(c & " is uppercase")"
you would fill an array of chars that are returned as UCase

Dim str As String = "aBc"
Dim ch As Char
Dim ContainsUppers As Boolean = False

For Each ch In str.ToCharArray

If ch = Char.ToUpper(ch) Then
ContainsUppers = True
Exit For
End If

Next

Dim strX As String = "aAbBc"

For i As Integer = 0 To strX.Length
If strX.SubString(i,1) = strX.SubString(i,1).ToUpper Then
MessageBox.Show("Uppercase on " + CStr(i) )
End If
Next

Dim c As Char
For Each c in "aAbBc"

Mika,
I would use Char.IsUpper that Herfried identified, the System.Char structure
has a number of shared functions that will check what "kind" of character
that was passed. Such as: IsControl, IsDigit, IsLetter, IsLetterOrDigit,
IsLower, IsNumber, IsPunctuation, IsSeparator, IsSurrogate, IsSymbol,
IsUpper, IsWhiteSpace.

You can also use Char.GetUnicodeCategory for similar information.

Hope this helps
Jay
