While on the server side you can do:

在服务器端,您可以执行以下操作:

Partial Public Class NorthwindCacheServerSyncProvider
    Private Sub ApplyChangeFailedEvent(…) Handles Me.ApplyChangeFailed
        Dim clientChanges As DataTable = e.Conflict.ClientChange
        Dim serverChanges As DataTable = e.Conflict.ServerChange
        ' Code to resolve conflict 
           If (clientChanges.Rows(0)("ModifiedDate") > _
               serverChanges.Rows(0)("ModifiedDate") Then e.Action =                      ApplyAction.RetryWithForceWrite 
           End If

You cant do this on the client, but, you can intercept the applying changes event and take appropriate action, like this...

您无法在客户端上执行此操作,但是,您可以拦截应用更改事件并采取适当的操作,例如......

Partial Public Class NorthwindCacheClientSyncProvider
    Private Sub ApplyingChangesEvent(…) Handles Me.ApplyingChanges
        Dim clientChanges As DataSet = e.Changes
