Number of columns in dataset

Question

Is it possible to find the number of columns a data set has?

I know we can find the length of rows with:

ds.Tables[0].Rows.length

Is there something similar for counting or returning the length of the columns?

Answer 1

You should look the properties of DataTable before asking this. As it should work.

ds.Tables[0].Columns.Count;

Answer 2

Use the DataTable.Columns.Count property. So ds.Tables[0].Columns.Count.

If you have a DataRow you can also use this property via...

int columnCount = row.Table.Columns.Count;

or another option is the DataRow.ItemArray which contains all fields:

int columnCount = row.ItemArray.Length;
