C#

Note that the MSDN sample uses the non-generic version of IEnumerable (where T : IEnumerable[T]), meaning that T can be any enumeration.

 interface IMyInterface<br />
    {<br />
    }<br />
<br />
    class Dictionary[TKey, TVal]<br />
      where TKey : IComparable, IEnumerable<br />
      where TVal : IMyInterface<br />
    {<br />
      public void Add (TKey key, TVal val)<br />
      {<br />
      }<br />
    }

You mean <code>where T : IEnumerable</code>

ya tat's wat im expecting

but how to i do it using regex

for tat i should use for loop.. isn't it..

is there any way in regex

string[] columns = inputLine.Split(',');//',' for .csv, '\t' if tab delimeters etc.

string ManArticleNo = columns[0];//or whatever index
