序列化对象的 ArrayList [英] Serialize ArrayList of Objects
问题描述
我有一个存储自定义对象的 ArrayList.我想将该 ArrayList 序列化为字符串,以便将其保存在应用程序设置中.
I have an ArrayList which stores a custom object. I want to serialize that ArrayList to a string so I can save it inside the Application settings.
这个问题看起来可以解决它,但在java中.而且我对 XML 并不聪明,所以有人可以帮忙吗?序列化Date对象类型的ArrayList
This question looks to resolve it, but is in java. And I am not smart with XML, so could someone help out? Serialize an ArrayList of Date object type
我有我的 ArrayList 设置:
I have my ArrayList setup:
...
MyObject tempObj = new MyObject("something",1,"something");
MyCollection.Add(tempObj);
...
我最初有这个.它输出字符串,但对象不存在:
And I originally had this. It outputs the string, but the object isn't there:
private string SerializeArrayList(ArrayList obj)
{
System.Xml.XmlDocument doc = new XmlDocument();
Type[] extraTypes = new Type[1];
extraTypes[0] = typeof(MyObject);
System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(ArrayList), extraTypes);
System.IO.MemoryStream stream = new System.IO.MemoryStream();
try
{
serializer.Serialize(stream, obj);
stream.Position = 0;
doc.Load(stream);
return doc.InnerXml;
}
catch { throw; }
finally
{
stream.Close();
stream.Dispose();
}
}
代码请求
public class MyObject
{
private string eN;
private Boolean bE;
private int min;
private Boolean bot;
private string onE;
public MyObject(string na, Boolean b)
{
...
}
public MyObject()
{
}
public string GetSomething()
{
...
推荐答案
我测试了你的代码,它似乎可以正常工作,只要你的对象上有 [Serializable]
.
I tested your code and it seems to work ok, as long as you have [Serializable]
on your object.
此外,如果您尝试序列化字段,则必须将它们设为公共属性.
Also if you are trying to Serialize the fields, you will have to make them public properties.
我的测试:
ArrayList array = new ArrayList();
Rules tempObj = new Rules { onE = "Value", min = 45, eN = "Value" };
array.Add(tempObj);
string result = SerializeArrayList(array);
private string SerializeArrayList(ArrayList obj)
{
XmlDocument doc = new XmlDocument();
XmlSerializer serializer = new XmlSerializer(typeof(ArrayList), new Type[]{typeof(Rules)});
using (MemoryStream stream = new System.IO.MemoryStream())
{
try
{
serializer.Serialize(stream, obj);
stream.Position = 0;
doc.Load(stream);
return doc.InnerXml;
}
catch (Exception ex)
{
}
}
return string.Empty;
}
对象:
[Serializable]
[XmlType(TypeName = "Rules")]
public class Rules
{
// Make fields propertys so they will be serialized
public string eN { get; set; } //Name
public Boolean bE { get; set; } //Whether blocked entirely
public int min { get; set; } //Minutes they are allowed if blocked
public Boolean bot { get; set; } //Create notification if allowance exceed
public string onE { get; set; } //Nothing or CLOSE Process
public Rules(string na, Boolean b)
{
}
public Rules()
{
}
}
