Public NotInheritable Class ForeignKeyColumn _
    Inherits NamedSmoObject
用法
Dim instance As ForeignKeyColumn
[SfcElementTypeAttribute("Column")]
public sealed class ForeignKeyColumn : NamedSmoObject
[SfcElementTypeAttribute(L"Column")]
public ref class ForeignKeyColumn sealed : public NamedSmoObject
[<SealedAttribute>]
[<SfcElementTypeAttribute("Column")>]
type ForeignKeyColumn =  
    class
        inherit NamedSmoObject
    end
public final class ForeignKeyColumn extends NamedSmoObject
