如何使用变量引用窗口 [英] How to reference a window using a variable

问题描述

我使用 SQL 数据库中的数据动态创建了一些窗口，并动态命名了它们.现在我想使用来自已单击标签的数据来引用它们.下面是一个基本示例.

I've created some windows dynamically, and named them dynamically, using data from an SQL database. Now I want to reference them using data from a label that has been clicked on. Below is a basic example.

private void buildWindow(string contentFromDataBase)
{
    Window fooWindow = new Window();
    fooWindow.Name = contentFromDataBase + "Window"
}

//Event handler for a label being clicked
private void showWindow(object sender, EventArgs e)
{
  //Now I want to get access to fooWindow via it's name, which is similar to the label name
  Label foo = sender as Label;
  foo.Name + "Window".show();
}

我该怎么做?

推荐答案

您需要通过 Name<在 Application.Current.Windows 中搜索您的 Window/code> 属性.

You need to search Application.Current.Windows for your Window by it's Name property.

var targetWindow = Application.Current.Windows
    .Cast<Window>()
    .Where(window => window.Name == String.Concat(foo.Name, "Window"))
    .DefaultIfEmpty(null)
    .Single();

if (targetWindow != null)
   targetWindow.Show();
