Merging Data Tables in C#

by pencilvac 3/9/2012 12:16:00 PM

Merging data tables in C# is incredibly easy. If you have two tables of data pulled from the database:

In this situation our two tables have the same columns.

using System.Data; //include in your code behind so you can use data tables.

 

DataTable dt = Contract.GetDealContracts(pCompanyID, -1,42);

DataTable dt2 = Contract.GetDealContracts(pCompanyID, -1, 40);

 

 

You can then merge the two tables into one by simply:

dt.Merge(dt2); // table1.Merge(table2);

 

BOOM- two tables, now one table, with all your data.
