GetGuid 方法

Gets the Guid value stored in the PipelineBuffer column.

此 API 不符合 CLS。 

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

语法

声明
<CLSCompliantAttribute(False)> _
Public Function GetGuid ( _
    columnIndex As Integer _
) As Guid
用法
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

参数

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

返回值

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

注释

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 在数据流中使用数据类型.
