Called just before EF intends to call ExecuteNonQueryAsync().

public virtual System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<int>> NonQueryExecutingAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<int> result, System.Threading.CancellationToken cancellationToken = default);

Public Overridable Function NonQueryExecutingAsync (command As DbCommand, eventData As CommandEventData, result As InterceptionResult(Of Integer), Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of InterceptionResult(Of Integer))

Parameters

command: DbCommand

The command.

eventData: CommandEventData

Contextual information about the command and execution.

result: InterceptionResult<Int32>

Represents the current result if one exists. This value will have HasResult set to true if some previous interceptor suppressed execution by calling SuppressWithResult(TResult). This value is typically used as the return value for the implementation of this method.

cancellationToken: CancellationToken

A CancellationToken to observe while waiting for the task to complete.

Returns

Task<InterceptionResult<Int32>>

ValueTask<InterceptionResult<Int32>>

If HasResult is false, the EF will continue as normal. If HasResult is true, then EF will suppress the operation it was about to perform and use Result instead. A normal implementation of this method for any interceptor that is not attempting to change the result is to return the result value passed in, often using FromResult<TResult>(TResult)

Implements

NonQueryExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Int32>, CancellationToken)

Exceptions

OperationCanceledException

If the CancellationToken is canceled.
