I am filling a dataset by running a stored procedure, and i am filling a datatable from the dataset.
DataSet RawDataSet = DataAccessHelper.RunProcedure("storedprocedureName");
//this will just return the dataset by running the procedure
DataTable RankTable = RawDataSet.Tables[0];
The Datatable has the below values:
Kamlakar Login 6/24/2014
Kamlakar Login 6/25/2014
Vinu Game 6/26/2014
Vinu Login 6/27/2014
Dilip Login 6/28/2014
Dilip Game 6/29/2014
Vinu Login 6/30/2014
Vinu Login 7/1/2014
Dilip Game 7/2/2014
Kamlakar Login 7/3/2014
Kamlakar Login 7/4/2014
Kamlakar Game 7/5/2014
I want to parse this dataTable and get how many times everyone has done an action, i.e how many times each row is repeated:
Kamlakar Login 3
Vinu Game 2
Vinu Login 4
Kamlakar Login 1
Kamlakar Game 2
I am new to C#. This can be done using count(*) in SQL but I need to do this using C#. Please let me know if there are any ways to achieve this.
I have searched SO but all posts are related to removing the duplicates/finding the duplicates, which does not solve my purpose.
