C# Datset with Sql Server Data Provider
The DataSet contains the copy of the data we requested through the SQL statement. The DataSet is a memory-resident representation of data that provides a consistent relational programming model regardless of the data source.
We can use Dataset in combination with SqlDataAdapter Class . Build and fill each DataTable in a DataSet with data from a data source using a DataAdapter. The C# SqlDataAdapter object allows us to populate Data Tables in a DataSet.
