Exempel

I följande exempel skrivs aktuella värden över med värden från databasen.

Northwnd db = new Northwnd("...");
try
{
    db.SubmitChanges(ConflictMode.ContinueOnConflict);
}

catch (ChangeConflictException e)
{
    Console.WriteLine(e.Message);
    foreach (ObjectChangeConflict occ in db.ChangeConflicts)
    {
        // All database values overwrite current values.
        occ.Resolve(RefreshMode.OverwriteCurrentValues);
    }
}

Dim db As New Northwnd("...")

Try
    db.SubmitChanges(ConflictMode.ContinueOnConflict)

Catch ex As ChangeConflictException
    Console.WriteLine(ex.Message)

    For Each occ As ObjectChangeConflict In db.ChangeConflicts
        ' All database values overwrite current values.
        occ.Resolve(Data.Linq.RefreshMode.OverwriteCurrentValues)
    Next

End Try

I följande exempel visas hur du växlar det ursprungliga värdet med de värden som hämtats från databasen. Inget aktuellt värde ändras.

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

catch (ChangeConflictException e)
{
    Console.WriteLine(e.Message);
    foreach (ObjectChangeConflict occ in db.ChangeConflicts)
    {
        //No database values are merged into current.
        occ.Resolve(RefreshMode.KeepCurrentValues);
    }
}

Try
    db.SubmitChanges(ConflictMode.ContinueOnConflict)

Catch ex As ChangeConflictException
    Console.WriteLine(ex.Message)

    For Each occ As ObjectChangeConflict In db.ChangeConflicts
        ' No database values are merged into current.
        occ.Resolve(Data.Linq.RefreshMode.KeepCurrentValues)
    Next

End Try

I följande exempel behålls de aktuella värden som har ändrats, men de andra värdena uppdateras med databasvärden.

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

catch (ChangeConflictException e)
{
    Console.WriteLine(e.Message);
    // Automerge database values for members that client
    // has not modified.
    foreach (ObjectChangeConflict occ in db.ChangeConflicts)
    {
        occ.Resolve(RefreshMode.KeepChanges);
    }
}

// Submit succeeds on second try.
db.SubmitChanges(ConflictMode.FailOnFirstConflict);

Try
    db.SubmitChanges(ConflictMode.ContinueOnConflict)

Catch ex As ChangeConflictException
    Console.WriteLine(ex.Message)

    For Each occ As ObjectChangeConflict In db.ChangeConflicts
        ' Automerge database values into current for members
        ' that client has not modified.
        occ.Resolve(Data.Linq.RefreshMode.KeepChanges)
    Next

End Try

' Submit succeeds on second try.
db.SubmitChanges(ConflictMode.FailOnFirstConflict)

Kommentarer

I följande exempel visas vilka resultat som genereras med hjälp av de olika värdena för RefreshMode.

public:
 void Resolve(System::Data::Linq::RefreshMode refreshMode, bool autoResolveDeletes);

public void Resolve(System.Data.Linq.RefreshMode refreshMode, bool autoResolveDeletes);

member this.Resolve : System.Data.Linq.RefreshMode * bool -> unit

Public Sub Resolve (refreshMode As RefreshMode, autoResolveDeletes As Boolean)
