속성 값

유형: System. . :: . .Object
The value of a column in the buffer by using its index in the array of buffer column indexes.

주의

The Script component developer does not use the ScriptBuffer class directly, but indirectly, through the derived classes in the BufferWrapper project item that represent the component's input and outputs.

The developer does not have to use the Item property, because the derived classes provide typed accessors for each buffer column, with property names that correspond to the column names.

예

The following sample code from the autogenerated BufferWrapper project item demonstrates how the Script component implicitly uses the Item method to retrieve a column from the buffer.

    Public ReadOnly Property [City]() As String
        Get
            Return CType(Me(1), String)
        End Get
    End Property
