OleDbCommand.Cancel Method

Definition

Tries to cancel the execution of an OleDbCommand.

public override void Cancel ();
public void Cancel ();

Implements

Examples

The following example creates an OleDbCommand, executes it, and 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 data source.

public void CreateCommand(string queryString, OleDbConnection connection)
{
    OleDbCommand command = new OleDbCommand(queryString, connection);
    command.Connection.Open();
    command.ExecuteReader();
    command.Cancel();
}

Remarks

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