語法

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

returnValue = instance.GetGuid(columnIndex)

[CLSCompliantAttribute(false)]
public Guid GetGuid(
    int columnIndex
)

[CLSCompliantAttribute(false)]
public:
Guid GetGuid(
    int columnIndex
)

[<CLSCompliantAttribute(false)>]
member GetGuid : 
        columnIndex:int -> Guid 

public function GetGuid(
    columnIndex : int
) : Guid

參數

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

傳回值

型別：System. . :: . .Guid
The Guid value stored in the PipelineBuffer column.

備註

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

If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You should first check for null by calling the IsNull method before retrieving the Guid from the buffer column.

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.
