Public ReadOnly Property IsForeignKey As Boolean
    Get
用法
Dim instance As Column
Dim value As Boolean

value = instance.IsForeignKey

[SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase)]
public bool IsForeignKey { get; }

[SfcPropertyAttribute(SfcPropertyFlags::None|SfcPropertyFlags::Standalone|SfcPropertyFlags::SqlAzureDatabase)]
public:
property bool IsForeignKey {
    bool get ();
}

[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase)>]
member IsForeignKey : bool

function get IsForeignKey () : boolean

属性值

类型：System. . :: . .Boolean
一个 Boolean 值，指定列是否为外键。
如果为 True，则列为外键。否则为 False（默认值）。

注释

The foreign key is the column referenced by a primary key column in another table.

注意注意

The value of the IsForeignKey property is always treated as false by columns based on the UserDefinedTableType object.
