Question

我有一个XML字符串，我想将其反序列化为强类型类。下面的代码工作得很好，直到我把它放入一个沙盒插件，此时我得到一个FileIOPermissions错误，因为我使用的是StringReader类。我在尝试反序列化时遇到问题而不使用StringReader。有没有人有一个很好的选择？

byte[] binary = Convert.FromBase64String(configurationWebResource.Attributes["content"].ToString());
resourceContent = UnicodeEncoding.UTF8.GetString(binary);

DataContractSerializer serializer = new DataContractSerializer(typeof(ViewSecurityConfiguration));

using (StringReader reader = new StringReader(resourceContent))
{
    using (XmlTextReader xmlReader = new XmlTextReader(reader))
    {
        if (serializer.IsStartObject(xmlReader))   //Throws FileIOPermissions error
        {
            currentViewSecurityConfiguration = (ViewSecurityConfiguration)(serializer.ReadObject(xmlReader));
        }
    }
}

尝试以下我在沙盒插件中成功运行的内容：

byte[] binary = Convert.FromBase64String(configurationWebResource.Attributes["content"].ToString());
resourceContent = UnicodeEncoding.UTF8.GetString(binary);

XmlSerializer serializer = new XmlSerializer(typeof(ViewSecurityConfiguration));

using (StringReader reader = new StringReader(resourceContent))
{
    currentViewSecurityConfiguration = (ViewSecurityConfiguration)serializer.Deserialize(reader);
}
