GetUInt64 方法

Gets the ulong value stored in the buffer 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 GetUInt64 ( _
    columnIndex As Integer _
) As ULong
用法
Dim instance As PipelineBuffer
Dim columnIndex As Integer
Dim returnValue As ULong

returnValue = instance.GetUInt64(columnIndex)

[CLSCompliantAttribute(false)]
public ulong GetUInt64(
    int columnIndex
)

[CLSCompliantAttribute(false)]
public:
unsigned long long GetUInt64(
    int columnIndex
)

[<CLSCompliantAttribute(false)>]
member GetUInt64 : 
        columnIndex:int -> uint64 

public function GetUInt64(
    columnIndex : int
) : ulong

参数

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

返回值

类型：System. . :: . .UInt64
The ulong value stored in the buffer column.

注释

This method works with the DT_UI8 data type in Integration Services.

If the buffer column DataType is not DT_UI8, the PipelineBuffer produces an UnsupportedBufferDataTypeException.

If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You can check for null by first 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.
