주의

The exception raised by CheckCancelled should be handled, and then rethrown.

예

In the following example, a UDF is defined that takes a very long time to execute. Occasionally, it calls CheckCancelled to determine if the function should exit:

public string LongRunning()
{

    try
    {
        //Enter a long running loop
        for (int nIndex = 0; nIndex < 1000; nIndex++)
        {
            //Exception generated when the query is canceled or Timeout occurs
            Context.CheckCancelled();
            System.Threading.Thread.Sleep(1000);
        }
    }
    catch (System.Exception ex)
    {
        Console.WriteLine(ex.Message);
        throw ex;
    }

    return "UDF Allowed to Finish";
}
