If you set the parent in the constructor, do not set the parent using this property. Setting the parent twice throws an exception.

If you use the default constructor, you must set this property and the Name property before you can set other properties.

示例

The following examples show how to set the Parent property when using the default constructor:

// Define a chronicle for the class
EventChronicle ec1 = new EventChronicle();
ec1.Name = "FlightEventChonicle";
ec1.Parent = flightEvents;
ec1.SqlStatements.Add("CREATE TABLE dbo.FlightEventChronicle " + 
    " (LeavingFrom nvarchar(6), GoingTo nvarchar(6), " +  
    " Price float);");
ec1.SqlStatements.Add("CREATE INDEX FlightEventChronicleIndex  " + 
    "ON dbo.FlightEventChronicle " + 
    "( LeavingFrom, GoingTo );");
flightEvents.EventChronicles.Add(ec1);

' Define a chronicle for the class
Dim ec1 As EventChronicle = New EventChronicle()
ec1.Name = "FlightEventChonicle"
ec1.Parent = flightEvents
ec1.SqlStatements.Add("CREATE TABLE dbo.FlightEventChronicle " + _
    " (LeavingFrom nvarchar(6), GoingTo nvarchar(6), " + _
    " Price float);")
ec1.SqlStatements.Add("CREATE INDEX FlightEventChronicleIndex  " + _
"ON dbo.FlightEventChronicle " + _
"( LeavingFrom, GoingTo );")
flightEvents.EventChronicles.Add(ec1)
