Read Method (SqlShimDataReader)

'Declaration
Public Overrides Function Read() As Boolean |

public override bool Read() |
Return Value
true if there are more rows; otherwise, false.
The following example creates a
Devart.Data.Dynamics.DynamicsConnection, a
Devart.Data.Dynamics.DynamicsCommand, and a
SqlShimDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the
SqlShimDataReader, then the
Devart.Data.Dynamics.DynamicsConnection.

public void ReadMyData(string myConnString)
{
string mySelectQuery = "SELECT contactid, lastname FROM contact";
DynamicsConnection dynamicsConnection = new DynamicsConnection(myConnString);
DynamicsCommand dynamicsCommand = new DynamicsCommand(mySelectQuery,dynamicsConnection);
dynamicsConnection.Open();
DynamicsDataReader dynamicsReader;
dynamicsReader = dynamicsCommand.ExecuteReader();
// Always call Read before accessing data.
while (dynamicsReader.Read()) {
Console.WriteLine(dynamicsReader.GetString(0) + ", " + dynamicsReader.GetString(1));
}
// always call Close when done reading.
dynamicsReader.Close();
// Close the connection when done with it.
dynamicsConnection.Close();
