Gets the bool value stored in the PipelineBuffer 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 Function GetBoolean ( _
    columnIndex As Integer _
) As Boolean
用法
Dim instance As PipelineBuffer
Dim columnIndex As Integer
Dim returnValue As Boolean

returnValue = instance.GetBoolean(columnIndex)

public bool GetBoolean(
    int columnIndex
)

public:
bool GetBoolean(
    int columnIndex
)

member GetBoolean : 
        columnIndex:int -> bool 

public function GetBoolean(
    columnIndex : int
) : boolean

参数

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

返回值

类型：System. . :: . .Boolean
The bool value stored in the PipelineBuffer column.

注释

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

If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You can check for null by 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 在数据流中使用数据类型.
