SqlCommand::Cancel Method ()
.NET Framework (current version)
Tries to cancel the execution of a SqlCommand.
Assembly: System.Data (in System.Data.dll)
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.
In some, rare, cases, if you call ExecuteReader then call Close (implicitily or explicitly) before calling Cancel, and then call Cancel, the cancel command will not be sent to SQL Server and the result set can continue to stream after you call Close. To avoid this, make sure that you call Cancel before closing the reader or connection.
