声明
<CLSCompliantAttribute(False)> _
Public Function GetColumnInfo ( _
    columnIndex As Integer _
) As BufferColumn

[CLSCompliantAttribute(false)]

CLSCompliantAttribute(false) 
public function GetColumnInfo (
    columnIndex : int
) : BufferColumn

参数

  • columnIndex
    The index of the column whose BufferColumn structure is retrieved.

返回值

The BufferColumn structure of the specified PipelineBuffer column.

备注

The BufferColumn contains information about the data stored in a PipelineBuffer column. This information can be used to prevent exceptions that might occur when assigning data to the buffer column. For example, columns with a fixed length such as the DT_STR, DT_TEXT, DT_WSTR, and DT_BYTES data types will fail if the data length is greater than the MaxLength of the BufferColumn.
