>>>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).
>>>Then I need to compare if a certain number (integer) is in the string. For example, say a variable iNumber is within the string. E.g. in pseudo code:
>>>

>>>iNumber = 3
>>>cString = "2,4,12"
>>>If (iNumber = Withint( cSring))
>>>{ 
>>>    // process
>>>}
>>>

>>>
>>>Any suggestions on how to compare the number (iNumber) to the content of the string? TIA.

>Both your code and Eric's code, when I am typing in my program do not have "Contains" in intellisense. That is, after I type . (period) Contains should be one of the method but it does not show. What am I missing?


Then use Array.IndexOf >= 0
