c# – WPF拦截绑定更新

伪代码：

public class Utils
{
    public void RegisterInterceptionOfBinding()
    {
        WpfBindingMechanism.OnSourceUpdating += SourceUpdating;
        WpfBindingMechanism.OnTargetUpdating += TargetUpdating;
    }

    private void SourceUpdating(object sender,SourceUpdatingEventArgs args)
    {
        if (DoSomeMagicConditionChecking)
        {
            args.Cancel = true;
        }
    }

    private void TargetUpdating(object sender,SourceUpdatingEventArgs args)
    {
        if (DoSomeMagicConditionChecking)
        {
            args.Cancel = true;
        }
    }
}

我正在寻找一种适用于整个WPF应用程序中所有绑定的机制.
