标签文本应绑定到字符串列表中的一个字符串.文本框也应绑定到字符串属性.您的文本框onchange事件或按钮可以在后面的代码或viewmodel中启动比较吗?

The label text should be bound to a string in a list of strings. The textbox should also be bound to a string property. Your textbox onchange event or button can then initiate a comparison in the code behind or viewmodel?
