Question

在 C＃和 Windows Phone SDK 中，我遇到了以下异常：“ WinRT信息：目标多字节代码中不存在Unicode字符的映射页即可。“。

我在Windows Phone 8的 Pivot应用程序上做了，我需要带有信息的 json 文件，其中包含'á'或'ý'等字符/ strong>即可。如何添加这些字符而没有例外？

这是方法，其中有例外：

private async void NavigationHelper_LoadState(object sender, LoadStateEventArgs e) { // TODO: Create an appropriate data model for your problem domain to replace the sample data var sampleDataGroup = await SampleDataSource.GetGroupAsync("Group-1"); this.DefaultViewModel[FirstGroupName] = sampleDataGroup; }

并且json文件看起来像这样：

{"Groups":[ { "UniqueId": "Group-1", "Title": "Group Title: 1", "Subtitle": "Group subtitle: 1", "ImagePath": "Assets/DarkGray.png", "Description" : "Group Description: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vivamus tempor scelerisque lorem in vehicula. Aliquam tincidunt, lacus ut sagittis tristique, turpis massa volutpat augue, eu rutrum ligula ante a ante", "Items": [ { "UniqueId": "Group-1-Item-1", "Title": "ý" /* !!!!this is the problem!!!! */, "Subtitle": "Item Subtitle: 1", "ImagePath": "Assets/LightGray.png", "Description" : "Item Description: Pellentesque porta, mauris quis interdum vehicula, urna sapien ultrices velit, nec venenatis dui odio in augue. Cras posuere, enim a cursus convallis, neque turpis malesuada erat, ut adipiscing neque tortor ac erat.", "Content" : "Curabitur class aliquam vestibulum nam curae maecenas sed integer cras phasellus." },

谢谢\ u00fd有效！顺便说一句，序列化程序是Windows Phone SDK中的dafault：

private async Task GetSampleDataAsync()
        {
            if (this._groups.Count != 0)
                return;

            Uri dataUri = new Uri("ms-appx:///DataModel/SampleData.json");

            StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(dataUri);
            string jsonText = await FileIO.ReadTextAsync(file);
            JsonObject jsonObject = JsonObject.Parse(jsonText);
            JsonArray jsonArray = jsonObject["Groups"].GetArray();

            foreach (JsonValue groupValue in jsonArray)
            {
                JsonObject groupObject = groupValue.GetObject();
                SampleDataGroup group = new SampleDataGroup(groupObject["UniqueId"].GetString(),
                                                            groupObject["Title"].GetString(),
                                                            groupObject["Subtitle"].GetString(),
                                                            groupObject["ImagePath"].GetString(),
                                                            groupObject["Description"].GetString());

                foreach (JsonValue itemValue in groupObject["Items"].GetArray())
                {
                    JsonObject itemObject = itemValue.GetObject();
                    group.Items.Add(new SampleDataItem(itemObject["UniqueId"].GetString(),
                                                       itemObject["Title"].GetString(),
                                                       itemObject["Subtitle"].GetString(),
                                                       itemObject["ImagePath"].GetString(),
                                                       itemObject["Description"].GetString(),
                                                       itemObject["Content"].GetString()));
                }
                this.Groups.Add(group);
            }
        }
