If AppSettings["OutReader"] currently have in it a string like: "(1,2)" then you can do:

var sections = ConfigurationManager.AppSettings["OutReader"].Replace("(",string.Empty)
                        .Replace(")",string.Empty)
                        .Split(',');
if(sections.Length > 0)
{
    int outrdr = Convert.ToInt32(sections[0]);
}

This can still throw an exception in the case that section[0] can't be parsed into an int so use .TryParse instead - Just wanted to stay as close to the question as possible

@Jay - please explain again what is currently not working. And when you do, please edit your original question (not adding a comment) with the current code and error you receive.

@Jay - the result is that outrdr contains the value 1 (starting from (1,2)). It is not possible to store the 2 as well in that single integer, but you can use sections[1] to access that using similar code.

string InReader = ConfigurationManager.AppSettings["InReader"].ToString(); string OutReader = ConfigurationManager.AppSettings["OutReader"].ToString(); directly it is working
