title: find the row number of a datatable column containing specific value C#
body: <p>I have a datatable in C# with a column called Point that contains various integer values. How do I find the row number of the first row that is equal to a specific value. E.g. Maybe I want to find the first time that the number 52 appears in the Point Column and it appears first at row 10. How do I find the value 10?</p>
  
  <p>Note that I want to find the row number and not the value of another column at this position, hence why this question is different to:
