LINQ to DataSet group by with specific column

Question

I have a dataset with following table

id      domain        email
1      google.com     av@et.org
2      apple.com      gopal@jt.com
3      abc.com        av@et.org
4      global.com     av@et.org
5      local.com      gopaljite@gmail.com
6      xyz.com        gopaljite@gmail.com
7      gpl.com        gopal@jt.com
8      mno.com        av@et.org
9      pqr.co.in      gopaljite@gmail.com
10     aad.com        av@et.org

Now I need output as following

Sr.      Email               Domain_Count
1       av@et.org             5
2       gopal@jt.com          2
3       gopaljite@gmail.com   3

How can I do this with LINQ ?

Thanks in advance.

Answer 1

var result=table.GroupBy(c => c.email)
                            .Select(group => new { 
                                  Email = group.Key, 
                                 Domain_Count = group.Count() 
                            }).OrderByDescending(x=> x.Domain_Count);

bind to GridView:

yourgidView.DataSource = result.ToList();
