Remarks
This overload of SubmitChanges() will use FailOnFirstConflict as the failure mode. To persist changes with a different mode, use SubmitChanges(ConflictMode) or SubmitChanges(ConflictMode, Boolean),
The version of changed list items will be incremented. To persist changes without incrementing versions, use SubmitChanges(ConflictMode, Boolean).
Examples
The following example shows this overload of SubmitChanges() being used:
foreach (TeamMember teamMember in teamSite.TeamMembers)
{
teamMember.TopTask = “Fiscal Planning”;
}
try
{
teamSite.SubmitChanges();
}
catch (ChangeConflictException e)
{
teamSite.ChangeConflicts.ResolveAll();
teamSite.SubmitChanges();
}
For Each teamMember As TeamMember In teamSite.TeamMembers
teamMember.TopTask = "Fiscal Planning"
Next teamMember
Try
teamSite. SubmitChanges()
Catch e As ChangeConflictException
teamSite.ChangeConflicts.ResolveAll()
teamSite. SubmitChanges()
End Try
