'用途
Dim instance As PipelineBuffer
Dim columnIndex As Integer
Dim value As Single

)
public:
void SetSingle(
int columnIndex,
float value

member SetSingle :
columnIndex:int *
value:float32 -> unit
public function SetSingle(
columnIndex : int,

參數
- columnIndex
型別：System.Int32
The index of the column in the buffer row.
- value
型別：System.Single
The value assigned to the buffer column.
備註
The SetSingle method assigns a float to the buffer column specified by the columnIndex parameter.
This method works with the DT_R4 data type in Integration Services.
If the value being assigned to the buffer column is not a float or the buffer column DataType is not DT_R4, an UnsupportedBufferDataTypeException occurs.
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.
