MemberChangeConflict.Resolve Method (RefreshMode)

Uses a RefreshMode parameter to automatically specify the value to set as the current value for the member in conflict.

Namespace:  System.Data.Linq
Assembly:  System.Data.Linq (in System.Data.Linq.dll)

public void Resolve(
	RefreshMode refreshMode
)

Parameters

refreshMode
Type: System.Data.Linq.RefreshMode

See RefreshMode.

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

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);
    }
}

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);
    }
}

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);
