"Order by Col1, Col2" using entity framework

"Order by Col1, Col2" using entity framework

In Entity Framework, you can use the OrderBy method to order the results of a query by one or more columns. To order by multiple columns, you can chain multiple OrderBy calls together.

For example, to order by Col1 and then by Col2, you could use the following code:

 var result = dbContext.Table .OrderBy(x => x.Col1) .ThenBy(x => x.Col2) .ToList();

This will order the results in ascending order by Col1, and then by Col2.

You can also use OrderByDescending and ThenByDescending to order in descending order.

 var result = dbContext.Table .OrderByDescending(x => x.Col1) .ThenByDescending(x => x.Col2) .ToList();

This will order the results in descending order by Col1, and then by Col2.
