SetSingle 方法

Assigns a float to a buffer column.

命名空间：  Microsoft.SqlServer.Dts.Pipeline
程序集：  Microsoft.SqlServer.PipelineHost（在 Microsoft.SqlServer.PipelineHost.dll 中）

语法

声明
Public Sub SetSingle ( _
    columnIndex As Integer, _
    value As Single _
)
用法
Dim instance As PipelineBuffer
Dim columnIndex As Integer
Dim value As Single

instance.SetSingle(columnIndex, value)

public void SetSingle(
    int columnIndex,
    float value
)

public:
void SetSingle(
    int columnIndex, 
    float value
)

member SetSingle : 
        columnIndex:int * 
        value:float32 -> unit 

public function SetSingle(
    columnIndex : int, 
    value : float
)

参数

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

• value
  类型：System. . :: . .Single
  The value assigned to the buffer column.

注释

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 在数据流中使用数据类型.
