如何使用反序列化对象? [英] How to use deserialized object?

问题描述

我正在为 Windows 8 应用程序在 C# 中序列化和反序列化一个对象.

I am serializing and deserializing an Object in C# for Windows 8 Apps.

我在将对象传递给下一个视图之前对其进行序列化，因为传递对象会抛出异常.

I am serializing my Object before passing it to the next View, because passing an object throws out exceptions.

函数 OnNavigatedTo:

function OnNavigatedTo:

protected override void OnNavigatedTo(NavigationEventArgs e)
{
   base.OnNavigatedTo(e);
   string XMLString = e.Parameter.ToString();
   var thisChannel = XmlDeserializeFromString(XMLString, typeof(Channel));
 ....}

反序列化函数:

  public static Channel XmlDeserializeFromString<Channel>(string objectData)
    {
        return (Channel)XmlDeserializeFromString(objectData, typeof(Channel));
    }

    public static object XmlDeserializeFromString(string objectData, Type type)
    {
        var serializer = new XmlSerializer(type);
        object result;

        using (TextReader reader = new StringReader(objectData))
        {
            result = serializer.Deserialize(reader);
        }

        return result;
    }

我想访问此对象中的数据，但类似:thisChannel.Name 不起作用.我不知道如何继续使用这个对象.

I want to access the data in this Object, but something like: thisChannel.Name doesn't work. And I don't know how that I can continue working with this Object.

推荐答案

从删除 var 开始:

 //var thisChannel = XmlDeserializeFromString(XMLString, typeof(Channel));
 Channel thisChannel = XmlDeserializeFromString(XMLString, typeof(Channel));

然后你至少会在错误的 object XmlDeserializeFromString() 被选择时得到一个错误.

and then you will at least get an error when the wrong object XmlDeserializeFromString() is selected.

并确保您使用正确的:

 Channel thisChannel = XmlDeserializeFromString<Channel>(XMLString);

重载应谨慎使用，一般不要与类型参数混合使用.

Overloading should be used with care and generally not mixed with Type parameters.
