{
"DrinksItems": [
    {
        "UniqueId": "Drinks-Item-1",
        "Title": "After Five",
        "ImagePath": "Assets/Drinks/AfterFive.png",
        "Description": "An After Five is a popular shooter that is often ...",
        "Ingredients": "1/2 oz (15ml) coffee liqueur",
        "Alcohol": "8.89",
        "Vodka": false,
        "Gin": false,
        "Whisky": false,
        "Beer": false,
        "Rum": false,

        "Popular": false,
        "Glass": "Shot",
        "Category": "Creamy Sour-Cream drink"
    },

我希望在按钮单击后将更改从false更新为JSON文件中的true。我怎么能这样做？

Answer 1

以编程方式在Windows Phone8.1中编辑Json文件
