找到工作区测量并在代码中设置一些属性以便它可以绑定到xaml中的Control的边距或高度/宽度属性是一个好习惯吗?
我这样做是为了让我的窗口根据可用的工作区调整大小.
const int w = SystemParameters.WorkArea.Width;
const int h = SystemParameters.WorkArea.Height;
public Thickness OuterGridMargin { get; }
MainViewModel()
{
OuterGridMargin = new Thickness(w/5,h/6,w/5,h/4);
}

我为一些外部容器执行此操作,以便布局不会以较低的分辨率混淆.目前我在20英寸的1600x900 res(96 dpi)下工作.我的应用程序是小工具,没有常规窗口.
我想知道是否有一些替代方法.
搜索[wpf]分辨率] 1提出了很多解决类似问题的问题,但我仍然陷入困境,无法得出如何实现良好的分辨率无关布局的结论.
任何人都可以提供关于如何在MVVM Light中使用信使类的样本/链接/简单插图/视频/演示吗?
我正在尝试为我的模型创建一个通用存储库.目前我有3种不同的型号,它们之间没有任何关系.(联系人,备注,提醒).
class Repository<T> where T:class
{
public IQueryable<T> SearchExact(string keyword)
{
//Is there a way i can make the below line generic
//return db.ContactModels.Where(i => i.Name == keyword)
//I also tried db.GetTable<T>().Where(i => i.Name == keyword)
//But the variable i doesn't have the Name property since it would know it only in the runtime
//db also has a method ITable GetTable(Type modelType) but don't think if that would help me
}

我不想让用户双击我的按钮.在第一次单击时,它应该被禁用,一旦我的代码被执行,我应该启用该按钮.怎么做 ?
我正在尝试从C#应用程序启动另一个应用程序,有没有办法在我的应用程序的mainform中显示这个应用程序?
谢谢,
我试图RaisePropertyChanged<T>(string propertyName, T oldValue, T newValue, bool broadcast)
让它工作,但无法让它工作.
我没有在任何现实世界的场景中实现它,只是为了学习它.如果我以通常的方式提高广播,那么它才有效
Messenger.Default.Send<PropertyUpdateeMessage>(new PropertyUpdateeMessage("test"));
所以我想知道我错过了什么 RaisePropertyChanged<T>(string propertyName, T oldValue, T newValue, bool broadcast)
提前致谢.
