Méthode GetString

Syntaxe

'Déclaration
Public Function GetString ( _
    columnIndex As Integer _
) As String
'Utilisation
Dim instance As PipelineBuffer
Dim columnIndex As Integer
Dim returnValue As String

returnValue = instance.GetString(columnIndex)

public string GetString(
    int columnIndex
)

public:
String^ GetString(
    int columnIndex
)

member GetString : 
        columnIndex:int -> string 

public function GetString(
    columnIndex : int
) : String

Notes

This method works with the following Integration Services data types:

• DT_STR

• DT_WSTR

If the value being assigned to the buffer column is not a string or the buffer column DataType is not a DT_STR, DT_WSTR, DT_TEXT, or DT_NTEXT, an UnsupportedBufferDataTypeException occurs.

If the value of the column is null, the PipelineBuffer produces a ColumnIsNullException. You can check for null by 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 Utilisation de types de données dans le flux de données.
