【问题描述】：

我正在使用查询字符串在两个 PhoneApplicationPages 之间传递数据，但目标页面将数据作为多个参数而不是一个大字符串接收。这是一个问题，因为我将数据作为 JSON 传递，如果它在中间流中被截断，则无法反序列化。

我传递的数据是：

NavigationService.Navigate("/MainPage.xaml?view=recipes&searchargs={"Author":null,"AuthorFilterType":2,"Categories":["1 Point","100-200 Calorie","1-3 grams Fat","3 Point","Baked Snack","Bakery & Baked Products","Banana","Beer","Boutique Wines","Bread","Breakfast","Breakfast Drinks","Cake","Cakes","Cocktails","Collectible Wines","Cookie","Cookie Dessert","Dairy","Dessert","Desserts","Diabetic","Drinks & Beverages","Fruit","Fruit Dessert","Fruit Drinks","Fruits","Gluten Free","High Fiber","Main Course","Main dish","Pasta","Pork","Raw Foods","Salads","Sandwiches","Shake & Smoothie","Side dish","Snack","Strawberry","Sweet Snack","Under 1 gram Fat","Under 100 Calorie","Vegetarian","Weight Watchers Points","Yogurt"],"Countries":[],"GlobalSearch":"","Ingredients":[],"MaxIngredients":0,"MinIngredients":0,"Name":null,"NameFilterType":2,"Rating":0,"Types":[]}");

但查询字符串包含以下内容：

这是一个错误吗？
