反序列化xml时路径中的非法字符？

Question

我有一个 xml，我需要反序列化为列表。实际上我只是使用 XSD2Code 工具来生成序列化和反序列化方法。

一切正常，但是当我传递文件名时，我得到了 xmlstring 但没有反序列化，因为 路径中有非法字符

我的代码：

    public  T LoadFromFile(string fileName)
    {
        System.IO.FileStream file = null;
        System.IO.StreamReader sr = null;
        try
        {
            file = new System.IO.FileStream(fileName, FileMode.Open, FileAccess.Read);
            sr = new System.IO.StreamReader(file);
            string xmlString = sr.ReadToEnd();
            sr.Close();
            file.Close();

            return Deserialize(xmlString);
        }
        finally
        {
            if ((file != null))
            {
                file.Dispose();
            }
            if ((sr != null))
            {
                sr.Dispose();
            }
        }
    }

这里我得到了 xmlString，我得到的字符串是 ...

请帮我找出错误

更新： 新增反序列化方法

public  T Deserialize(string xml)
{
   // System.IO.StringReader stringReader = null;
    StreamReader stream = null;
    try
    {
        Serializer = new System.Xml.Serialization.XmlSerializer(typeof(T));

        stream = new StreamReader(xml);

       // stringReader = new System.IO.StringReader(xml);
        return ((T)(Serializer.Deserialize(System.Xml.XmlReader.Create(stream))));
    }
    finally
    {
        if ((stream != null))
        {
            stream.Dispose();
        }
    }
}

好的，现在我们已经有了你的Deserialize 方法，问题很明显：

stream = new StreamReader(xml);

这将xml 视为文件名，而不是XML。要么你应该有：

public T Deserialize(string filename)
{
    // There's no need to make the serializer a property or instance variable...
    var serializer = new XmlSerializer(typeof(T));
    using (var stream = File.OpenRead(filename))
    {
        return (T) serializer.Deserialize(stream);
    }
}

... 或 使其采用 XML，并使用 StringReader:

public T Deserialize(string xml)
{
    var serializer = new XmlSerializer(typeof(T));
    return (T) serializer.Deserialize(new StringReader(xml));
}

我个人更喜欢前一个版本 - 它允许 XML 解析代码自动检测编码，而目前当您将文件作为字符串读取时，您假设 UTF-8。
