If you're using Visual Studio 2008 try the following
Dim numberStrings = TextBox1.Text.Split(","c).Select(Function(x) x.Trim())) ColorDialog1.CustomColors = numberStrings.Select(Function(x) CInt(x)).ToArray()Here's a version for 2005
Dim list as New List(Of String)(TextBox1.Text.Split(","c) Dim numbers as New List(Of Integer) For i as Integer = 0 to list.Count - 1 list(i) = list(i).Trim() numbers.Add(CInt(list(i)) Next ColorDialag1.CustomColors = numbers.ToArray()I__ : it says 1 dimensional array cannot be converter to CHARI__ : the error pertains to this New String() {","}JaredPar : @avrohom try again. I updated the code.I__ : Unable to cast object of type 'WhereSelectArrayIterator`2[System.String,System.String]' to type 'System.String[]'. for the second line of the first block of codeMarc : You're stuffing a IEnumerableinto a String[], which won't work. Toss a .ToArray() at the end of your trim line. JaredPar : @avrohom, hah. That's what I get for not trying it in a compiler. I updated it again, it should work this timeI__ : excellent thank you very much it works. i have another problem that i will post up right nowMarc : @Jared - may want to specify .NET 3.5 versus 2.0 instead of the IDE versions, since you can target 2.0 (no LINQ available) just fine with VS 2008JaredPar : @Marc, actually you can use LINQ just fine while targeting 2.0. As long as there are appropriate bindable extension methods LINQ works fine without System.Core. LINQBridge is the most popular 2.0 library although there are a couple available.From JaredPar -
string s = "1,2,3,4"; int[] n = Array.ConvertAll(s.Split(','), (item => Convert.ToInt32(item)));From shahkalpesh
