System_CAPS_pubmethodIsDBNullAsync(Int32)

An asynchronous version of IsDBNull, which gets a value that indicates whether the column contains non-existent or missing values.(Inherited from DbDataReader.)

System_CAPS_pubmethodIsDBNullAsync(Int32, CancellationToken)

An asynchronous version of IsDBNull, which gets a value that indicates whether the column contains non-existent or missing values. Optionally, sends a notification that operations should be cancelled.(Inherited from DbDataReader.)

System_CAPS_pubmethodNextResult()

Advances the DataTableReader to the next result set, if any.(Overrides DbDataReader.NextResult().)

System_CAPS_pubmethodNextResultAsync()

An asynchronous version of NextResult, which advances the reader to the next result when reading the results of a batch of statements.

Invokes NextResultAsync with CancellationToken.None.(Inherited from DbDataReader.)

System_CAPS_pubmethodNextResultAsync(CancellationToken)

This is the asynchronous version of NextResult. Providers should override with an appropriate implementation. The cancellationToken may optionally be ignored.

The default implementation invokes the synchronous NextResult method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by NextResult will be communicated via the returned Task Exception property.

Other methods and properties of the DbDataReader object should not be invoked while the returned Task is not yet completed.(Inherited from DbDataReader.)

System_CAPS_pubmethodRead()

Advances the DataTableReader to the next record.(Overrides DbDataReader.Read().)

System_CAPS_pubmethodReadAsync()

An asynchronous version of Read, which advances the reader to the next record in a result set. This method invokes ReadAsync with CancellationToken.None.(Inherited from DbDataReader.)

System_CAPS_pubmethodReadAsync(CancellationToken)

This is the asynchronous version of Read. Providers should override with an appropriate implementation. The cancellationToken may optionally be ignored.

The default implementation invokes the synchronous Read method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by Read will be communicated via the returned Task Exception property.

Do not invoke other methods and properties of the DbDataReader object until the returned Task is complete.(Inherited from DbDataReader.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
