How To Compare Two Tables In C#. You can return the data table which will be the difference of two input data table and later you can perform operations on the resulting. It receives 2 datatable instances. This article describes you how to compare datatables to get matched, unmatched, combine the list of all rows in both tables. For comparing the rows in 2 datatables, you do not need to have nested loops. You would need to loop through the rows of each table, and then through each column within that loop to compare individual values. We can just do a linear scan through 2 datatables. I have this code which compares data from two data tables. Using the primarykey property of the datatable, which will accept an array of columns, should help. You can compare two datatables by matching the columns and perform minus operations as you do in rdbms. Here, we introduce the comparerows method. It does this by using a primary column and inserting the new record from table2. You can use datatable extension methods like except to get matched datarows, intersect to get unmatched datarows and union to get a unique combine list of datarows from all datatables.
