如何将xml反序列化为对象数组? [英] How to Deserialize xml to an array of objects?
问题描述
我正在尝试将xml文件反序列化为对象[]-该对象是具有以下字段的矩形
I am tryind to deserialize a xml file into an object[] - the object is a rectangle with the following fields
public class Rectangle : IXmlSerializable
{
public string Id { get; set; }
public Point TopLeft { get; set; }
public Point BottomRight { get; set; }
public RgbColor Color { get; set; }
}
我创建了几个矩形,将它们保存到数组中并设法对其进行序列化到xml中,我得到以下语法:
I created several rectangles, saved them into an array and managed to serialize them into the xml i get the following syntax:
<?xml version="1.0" encoding="utf-8" ?>
- <Rectangles>
- <Rectangle>
<ID>First one</ID>
- <TopLeft>
<X>0.06</X>
<Y>0.4</Y>
</TopLeft>
- <BottomRight>
<X>0.12</X>
<Y>0.13</Y>
</BottomRight>
- <RGB_Color>
<Blue>5</Blue>
<Red>205</Red>
<Green>60</Green>
</RGB_Color>
</Rectangle>
-
现在我想反序列化矩形对象重新变成新的矩形[]
我应该怎么做?
Now i want to deserialize the rectangle objects back into a new rectangle[] how should i do it?
XmlSerializer mySerializer = new XmlSerializer(typeof(Rectangle));
FileStream myFileStream = new FileStream("rectangle.xml", FileMode.Open);
Rectangle[] r = new Rectangle[] {};
Rectangle rec;
for (int i = 0; i < 3; i++)
{
r[i] = (Rectangle) mySerializer.Deserialize(myFileStream);
}
我得到一个InvalidOperationException-{ XML文档中有一个错误(1 ,40)。}
我在做什么错了?
i get a InvalidOperationException - {"There is an error in XML document (1, 40)."} what am i doing wrong?
谢谢
推荐答案
如果您的XML文档有效,则应该可以使用以下代码对其进行反序列化:
If your XML document is valid, you should be able to use this codes to deserialize it:
XmlSerializer mySerializer = new XmlSerializer( typeof( Rectangle[] ), new XmlRootAttribute( "Rectangles" ) );
using ( FileStream myFileStream = new FileStream( "rectangle.xml", FileMode.Open ) )
{
Rectangle[] r;
r = ( Rectangle[] ) mySerializer.Deserialize( myFileStream );
}
