以静态方法访问WPF名称属性

Question

我有一个WPF应用程序.在其中一个XAML中我使用了Name属性,如下所示

 x:Name="switchcontrol"

我必须使用this.switchcontrol 我的问题访问.cs文件中的控件/属性,我需要以静态方法访问控件

public static getControl()
{
 var control = this.switchcontrol;//some thing like that
}

怎么做到这一点？

this静态方法无法访问.您可以尝试在静态属性中保存对实例的引用,例如:

public class MyWindow : Window
{

    public static MyWindow Instance { get; private set;}

    public MyWindow() 
    {
        InitializeComponent();
        // save value
        Instance = this; 
    }

    public static getControl()
    {
        // use value
        if (Instance != null)
            var control = Instance.switchcontrol; 
    }

    protected override void OnClosed(EventArgs e)
    {
        base.OnClosed(e);
        Instance = null; // remove reference, so GC could collect it, but you need to be sure there is only one instance!!
    }

}
