>>>>>>>Hi,

>>>>>>>My title is not very clear so I will explain what I am looking for. I have an XML file that my ASP.NET application reads into a dataset. One of the columns of the dataset has a string of the following format (examples):
>>>>>>>"1,3,29"
>>>>>>>"2"
>>>>>>>"4,5,1"
>>>>>>>That is the string contains number(s) separated by commas (btw, if the answer to my question involves changing the separator from comma to something different, I can do it).

>>>>>>>iNumber = 3
>>>>>>>cString = "2,4,12"
>>>>>>>If (iNumber = Withint( cSring))

int iNumber = 2;
>>>>>>string cstring = "2,4,12";
>>>>>>
>>>>>>bool isWithin = cstring.Split(',').FirstOrDefault(x => Convert.ToInt32(x) == iNumber) != null;

bool isWithin = Array.IndexOf(cstring.Split(','), iNumber.ToString()) > 0;

VERY unlikely. I've moved through every VS version and cannot recall a problem.....
