Namespace: System.Data.OleDb

Syntax

C++

Copy

public override void Cancel()

Implements

IDbCommand.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.

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.

Copy


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