OracleCommand.Cancel Method

Attempts to cancel the execution of an OracleCommand.

Namespace:  System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

public override void Cancel()

Implements

IDbCommand.Cancel()

If there is nothing to cancel, nothing happens. However, if there is a command in process, and the attempt to cancel fails, no exception is generated.

The following example creates an OracleCommand, executes it, then cancels the execution. To accomplish this, the method is passed a string that is an SQL SELECT statement and a string to use to connect to the database.

public void CreateOracleCommand(string queryString, string connectionString)
{
    using (OracleConnection connection = new OracleConnection(connectionString))
    {
        OracleCommand command = new OracleCommand(queryString, connection);
        command.Connection.Open();
        command.ExecuteReader();
        command.Cancel();
    }
}
