MemberChangeConflict.Resolve Method

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

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

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

Public Sub Resolve (refreshMode As RefreshMode)

Parameters

Examples

The following example overwrites current values with values from the database.

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

The following example shows how to swap the original value with the values retrieved from the database. No current value is modified.

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

The following example keeps the current values that have been changed, but updates the other values with database values.

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)

Remarks

The following examples show what results are produced by using the various values for RefreshMode.

public:
 void Resolve(System::Object ^ value);

public void Resolve (object value);

member this.Resolve : obj -> unit

Public Sub Resolve (value As Object)

Parameters

Remarks

The value set here is the value to be used in a subsequent SubmitChanges operation.
