如何在 Windows Phone 8 中创建一个空的 xml [英] How to create an empty xml in Windows Phone 8

问题描述

我正在像这样在我的 WP8 应用程序中创建一个空的 xml 文件

I'm creating an empty xml file in my WP8 app like this

    public static bool create()
    {
        Dictionary<string, object> __data = new Dictionary<string, object>();
        XmlWriterSettings xmlWriterSettings = new XmlWriterSettings();
        xmlWriterSettings.Indent = true;

        using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
        {
            using (IsolatedStorageFileStream stream = myIsolatedStorage.OpenFile("Data.xml", FileMode.Create))
            {
                XmlSerializer serializer = new XmlSerializer(typeof(List<DataModel>));
                using (XmlWriter xmlWriter = XmlWriter.Create(stream, xmlWriterSettings))
                {
                    serializer.Serialize(stream, __data);
                }
            }
        }
        return true;
    }

但是我在 serializer.Serialize(stream, __data);

我做错了什么?

编辑:我在创建新字典后添加了这一行 __data.Add("testkey", "testdatavalue"); 但我仍然遇到相同的异常.

Edit: I added this line after creating the new dictionary __data.Add("testkey", "testdatavalue"); but I still get the same exception.

推荐答案

我们有

Dictionary<string, object> __data = ...
XmlSerializer serializer = new XmlSerializer(typeof(List<DataModel>));
serializer.Serialize(stream, __data);

所以你的序列化器是用于另一种类型(DataModel).它不会处理 Dictionary<>.

So your serializer is for another Type (DataModel). It won't handle a Dictionary<>.
