Stored procedure is returning set of columns of data like name, age and height. At the application level, in c# how can we apply the aggregate functions to get average height, min age and max age on the data.

Actually i can have any stored procedure getting executed at this point with varied columns coming out, on top of that data table i might have to apply the aggregate functions. Please suggest

What I have tried:

I know the way to handle it if i have to execute only one proc, but at this point i am not aware what would be the return columns for my proc

DataTable dt = new DataTable();
      dt.Columns.Add("name");
      dt.Columns.Add("age");
      dt.Columns.Add("height");
      dt.Rows.Add("AA", 25, 5.2);
      dt.Rows.Add("bb", 26, 4.2);
      dt.Rows.Add("cc", 28, 6.2);
      dt.Rows.Add("dd", 30, 7);
      var average = dt.Rows.OfType<DataRow>().Select(k => Convert.ToDouble(k["height"])).Average();
      var ages = dt.Rows.OfType<DataRow>().Select(k => Convert.ToInt32(k["age"]));
      int minage = ages.Min();
      int max = ages.Max();
