Checks to see if the data in a buffer column is null.

Namespace:   Microsoft.SqlServer.Dts.Pipeline
Assembly:  Microsoft.SqlServer.PipelineHost (in Microsoft.SqlServer.PipelineHost.dll)

Syntax

public bool IsNull(
    int columnIndex
)

public:
bool IsNull(
    int columnIndex
)

member IsNull : 
        columnIndex:int -> bool

Public Function IsNull (
    columnIndex As Integer
) As Boolean

Parameters

  • columnIndex
    Type: System.Int32

    The index of the column in the buffer row.

Return Value

true if the column contains null; otherwise, false.

Remarks

It is recommended that you call the IsNull method prior to calling a data type accessor method, such as GetBoolean, because the PipelineBuffer will produce a ColumnIsNullException if the column is null.
