Find longest string in every DataTable column

Hi Experts

In this question I was able to get the length of the longest text in every column, can we modify the method to get the string itself, not the length ? To make it a little more clearer, assuming the tblData have 6 columns, the maxLenCols List should have 6 strings representing the longest string in every column.
maxLenCols =
            Enumerable.Range(0, tblData.Columns.Count)
            .Select(col => tblData.AsEnumerable()
            .Select(row => (row[col]).ToString()).OfType<string>()
            .Max(val => val.Length)).ToList();

Many thanks.

Hi Faraj1969;

Try this, it should give you what you are looking for.

var macString = 
  Enumerable.Range(0, dt.Columns.Count)
    .Select(col => dt.AsEnumerable()
    .Select(row => (row[col]).ToString()).OfType<string>()
    .Aggregate("", (output, next) => (next.Length > output.Length) ? next : output)).ToList();

Great solution, direct to the point.

Sorry for the simplicity of my question, but when it comes to Linq, I'm a total newbie.

Many thanks mate.
