如何在文件中保存/恢复可序列化对象? [英] How to save/restore serializable object to/from file?
本文介绍了如何在文件中保存/恢复可序列化对象?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个对象列表,我需要将它保存在我电脑的某个地方.我读过一些论坛,我知道对象必须是 Serializable
.但如果我能举个例子就好了.例如,如果我有以下内容:
I have a list of objects and I need to save that somewhere in my computer. I have read some forums and I know that the object has to be Serializable
. But it would be nice if I can get an example. For example if I have the following:
[Serializable]
public class SomeClass
{
public string someProperty { get; set; }
}
SomeClass object1 = new SomeClass { someProperty = "someString" };
但是我如何将 object1
存储在我的计算机中的某个位置并稍后检索?
But how can I store object1
somewhere in my computer and later retrieve?
推荐答案
您可以使用以下内容:
/// <summary>
/// Serializes an object.
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="serializableObject"></param>
/// <param name="fileName"></param>
public void SerializeObject<T>(T serializableObject, string fileName)
{
if (serializableObject == null) { return; }
try
{
XmlDocument xmlDocument = new XmlDocument();
XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
using (MemoryStream stream = new MemoryStream())
{
serializer.Serialize(stream, serializableObject);
stream.Position = 0;
xmlDocument.Load(stream);
xmlDocument.Save(fileName);
}
}
catch (Exception ex)
{
//Log exception here
}
}
/// <summary>
/// Deserializes an xml file into an object list
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="fileName"></param>
/// <returns></returns>
public T DeSerializeObject<T>(string fileName)
{
if (string.IsNullOrEmpty(fileName)) { return default(T); }
T objectOut = default(T);
try
{
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load(fileName);
string xmlString = xmlDocument.OuterXml;
using (StringReader read = new StringReader(xmlString))
{
Type outType = typeof(T);
XmlSerializer serializer = new XmlSerializer(outType);
using (XmlReader reader = new XmlTextReader(read))
{
objectOut = (T)serializer.Deserialize(reader);
}
}
}
catch (Exception ex)
{
//Log exception here
}
return objectOut;
}
