Gets the ulong value stored in the buffer column.

此 API 不符合 CLS 標準。 

命名空間：  Microsoft.SqlServer.Dts.Pipeline

語法

'宣告
<CLSCompliantAttribute(False)> _
Public Function GetUInt64 ( _
    columnIndex As Integer _
) As ULong
'用途
Dim instance As PipelineBuffer
Dim columnIndex As Integer
Dim returnValue As ULong

returnValue = instance.GetUInt64(columnIndex)

[CLSCompliantAttribute(false)]
public ulong GetUInt64(
    int columnIndex
)

[CLSCompliantAttribute(false)]
public:
unsigned long long GetUInt64(
    int columnIndex
)

[<CLSCompliantAttribute(false)>]
member GetUInt64 : 
        columnIndex:int -> uint64 

public function GetUInt64(
    columnIndex : int
) : ulong

參數

• columnIndex
  型別：System. . :: . .Int32
  The index of the column in the buffer row.

傳回值

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

備註

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 使用資料流程中的資料類型.
