방법: 엔터티 충돌 정보 검색
ObjectChangeConflict 클래스의 개체를 사용하여 ChangeConflictException 예외로 인해 발생한 충돌에 대한 정보를 제공할 수 있습니다. 자세한 내용은 낙관적 동시성: 개요를 참조하세요.
예시
다음 예제에서는 누적된 충돌 목록을 반복합니다.
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()
