Instantiate IDataAdapter from instance of IDbConnection

Instantiate IDataAdapter from instance of IDbConnection

To instantiate an IDataAdapter from an instance of IDbConnection in C#, you can create a new instance of the DataAdapter class and set its SelectCommand property to a new instance of the IDbCommand interface that represents the SELECT statement to execute.

Here's an example:

using System.Data; using System.Data.SqlClient; // Replace with the appropriate data provider namespace IDbConnection connection = new SqlConnection("connectionString"); IDbCommand command = connection.CreateCommand(); command.CommandText = "SELECT * FROM MyTable"; IDataAdapter adapter = new SqlDataAdapter(); adapter.SelectCommand = command;

In this example, an instance of IDbConnection is created using a connection string for the SQL Server database. An instance of IDbCommand is created and its CommandText property is set to a SELECT statement. Finally, a new instance of the DataAdapter class is created, and its SelectCommand property is set to the IDbCommand instance.

By creating a DataAdapter instance in this way, you can execute a SELECT statement against a database using an IDbConnection instance in C#. Note that you may need to replace SqlDataAdapter with the appropriate data provider class, depending on the database you are using.
