示例

在下面的示例中, 检索有关发生冲突的对象db.ChangeConflicts的信息, 表示这些对象的集合。In the following example that retrieves information about objects in conflict, db.ChangeConflicts represents the collection of those objects.

Northwnd db = new Northwnd("...");

try
{
    db.SubmitChanges(ConflictMode.ContinueOnConflict);
}

catch (ChangeConflictException e)
{
    Console.WriteLine("Optimistic concurrency error.");
    Console.WriteLine(e.Message);
    foreach (ObjectChangeConflict occ in db.ChangeConflicts)
    {
        MetaTable metatable = db.Mapping.GetTable(occ.Object.GetType());
        Customer entityInConflict = (Customer)occ.Object;
        Console.WriteLine("Table name: {0}", metatable.TableName);
        Console.Write("Customer ID: ");
        Console.WriteLine(entityInConflict.CustomerID);
        Console.ReadLine();
    }
}
Dim db As New Northwnd("...")

Try
    db.SubmitChanges(ConflictMode.ContinueOnConflict)

Catch ex As ChangeConflictException
    Console.WriteLine("Optimistic concurrency error.")
    Console.WriteLine(ex.Message)
    For Each occ As ObjectChangeConflict In db.ChangeConflicts
        Dim metatable As MetaTable = db.Mapping.GetTable(occ.Object.GetType())
        Dim entityInConflict = occ.Object

        Console.WriteLine("Table name: " & metatable.TableName)
        Console.Write("Customer ID: ")
        Console.WriteLine(entityInConflict.CustomerID)
        Console.ReadLine()
    Next
End Try
