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.
