Parametri

Valore restituito

Tipo: System. . :: . .UInt64
The ulong value stored in the buffer column.

Osservazioni

This method works with the DT_UI8 data type in Integration Services.

If the buffer column DataType is not DT_UI8, the PipelineBuffer produces an UnsupportedBufferDataTypeException.

If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You can check for null by first calling the IsNull method.

For a complete list of Integration Services data types and the corresponding Get and Set methods of the PipelineBuffer class to use with each type, see Utilizzo di tipi di dati nel flusso di dati.
