C# ADO.NET DataAdapter

DataAdapter is a part of the ADO.NET Data Provider. DataAdapter provides the communication between the Dataset and the Datasource. We can use the DataAdapter in combination with the DataSet Object. DataAdapter provides this combination by mapping Fill method, which changes the data in the DataSet to match the data in the data source, and Update, which changes the data in the data source to match the data in the DataSet. That is, these two objects combine to enable both data access and data manipulation capabilities.
