反序列化xml时路径中的非法字符
本文关键字：非法 字符 路径 xml 反序列化 | 更新日期: 2023-09-27 18:12:11
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。
都工作得很好，但当我传递文件名时，我得到了xmlstring，但没有反序列化，因为路径
中的非法字符My Code:
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和字符串我得到的是…

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();
}
}
}
好了，现在我们有了Deserialize方法，问题很明显:
stream = new StreamReader(xml);
这将xml视为文件名，而不是XML。或者你只需要输入:
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);
}
}
…或使其接受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，假设是UTF-8。
