C# 之对象与Xml序列化工具类

写在前面

一个常用的对象与Xml序列化工具类，使用系统类库System.Xml，序列化时需要注意只能将对象的公共字段和读/写属性转换为 XML。不转换方法、索引器、私有字段或只读属性。另外XmlSerializer 类无法序列化ArrayList数组和List<T>数组。

代码实现

    public class ObjectSerializer<T> where T : class
    {
        public void SerializeToXml(string filePath, object target)
        {
            var dir = Path.GetDirectoryName(Path.GetFullPath(filePath));
            if (string.IsNullOrWhiteSpace(dir) || !Directory.Exists(dir))
                throw new Exception("File Path Invalid");

            using (var writer = new StreamWriter(filePath))
            {
                var xmlSerializer = new XmlSerializer(typeof(T));
                xmlSerializer.Serialize(writer, target);
            }
        }

        public string SerializeToXml(T target)
        {
            using (var writer = new StringWriter())
            {
                var xmlSerializer = new XmlSerializer(typeof(T));
                xmlSerializer.Serialize(writer, target);
                return writer.ToString();
            }
        }

        public T DeserializeFromString(string xml)
        {
            var xmlSerializer = new XmlSerializer(typeof(T));
            using (StringReader sr = new StringReader(xml))
            {
                return xmlSerializer.Deserialize(sr) as T;
            }
        }

        public T DeserializeFromXml(string filePath)
        {
            if (!File.Exists(filePath))
                throw new Exception("File Path Invalid");

            try
            {
                using (var reader = new StreamReader(filePath))
                {
                    var xmlSerializer = new XmlSerializer(typeof(T));
                    return (T)xmlSerializer.Deserialize(reader);
                }
            }
            catch (Exception ex)
            {
                return null;
            }
        }
    }
