英文:
C# List<> property to XML
问题
这是您提供的代码片段的翻译：
获得了这段代码...
public class CardLogos
{
[XmlElement("Card")]
public string Card { get; set; }
}
public class P_M
{
[XmlElement("Cards")]
public List<CardLogos> Cards { get; set; }
}
尝试构建Cards属性:
pm = new P_M();
...其他属性设置发生在这里
pm.Cards = new List<CardLogos>();
pm.Cards.Add(new CardLogos() {Card="VISA"});
pm.Cards.Add(new CardLogos() {Card="AMEX"});
pm.Cards.Add(new CardLogos() {Card="DISCOVER"});
但序列化的XML输出如下:
<P_M>
<Other Properties>
<Cards>
<Card>VISA</Card>
</Cards>
<Cards>
<Card>AMEX</Card>
</Cards>
<Cards>
<Card>DISCOVER</Card>
</Cards>
</P_M>
如何使其输出如下:
<P_M>
<Other Properties>
<Cards>
<Card>VISA</Card>
<Card>AMEX</Card>
<Card>DISCOVER</Card>
</Cards>
</P_M>
英文:
Got this code...
public class CardLogos
{
[XmlElement("Card")]
public string Card { get; set; }
}
public class P_M
{
[XmlElement("Cards")]
public List<CardLogos> Cards { get; set; }
}
Trying to build the Cards property:
pm = new P_M();
...Other property setting happens here
pm.Cards = new List<CardLogos>();
pm.Cards.Add(new CardLogos() {Card="VISA"});
pm.Cards.Add(new CardLogos() {Card="AMEX"});
pm.Cards.Add(new CardLogos() {Card="DISCOVER"});
But the serialized XML comes out like this:
<P_M>
<Other Properties>
<Cards>
<Card>VISA</Card>
</Cards>
<Cards>
<Card>AMEX</Card>
</Cards>
<Cards>
<Card>DISCOVER</Card>
</Cards>
</P_M>
How can I make it come out like this:
<P_M>
<Other Properties>
<Cards>
<Card>VISA</Card>
<Card>AMEX</Card>
<Card>DISCOVER</Card>
</Cards>
</P_M>

得分: 1
试试这个：
```csharp
public class P_M
{
[XmlArray("Cards")]
[XmlArrayItem(ElementName= "Card")]
public List<CardLogos> Cards { get; set; }
}
public class CardLogos
{
[XmlText]
public string Card { get; set; }
}
它保留了所有原始类型，而不需要将其简化为 List<string>。CardLogos 中可能有的其他属性可以使用 XmlIgnore 属性跳过。
<details>
<summary>英文:</summary>
Try this:
public class P_M
{
[XmlArray("Cards")]
[XmlArrayItem(ElementName= "Card")]
public List<CardLogos> Cards { get; set; }
}
public class CardLogos
{
[XmlText]
public string Card { get; set; }
}
It preserves all of the original types, without needing to reduce down to a `List<string>`. Any other properties you may have in `CardLogos` can be skipped over with `XmlIngore` attributes.

**得分**: 0
你可以使用 [`XmlArray`][1] 和 [`XmlArrayItem`][2] 属性，并将 `Cards` 改为字符串列表：
```csharp
public class P_M
{
[XmlArray("Cards")]
[XmlArrayItem(ElementName = "Card")]
public List<string> Cards { get; set; }
}
结果如下：
<?xml version="1.0" encoding="utf-8"?>
<P_M xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Cards>
<Card>VISA</Card>
<Card>AMEX</Card>
<Card>DISCOVER</Card>
</Cards>
</P_M>
查看示例。
英文:
You can use the XmlArray and XmlArrayItem attributes and change Cards to a list of strings:
public class P_M
{
[XmlArray("Cards")]
[XmlArrayItem(ElementName= "Card")]
public List<string> Cards { get; set; }
}
This results in:
<?xml version="1.0" encoding="utf-8"?>
<P_M xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Cards>
<Card>VISA</Card>
<Card>AMEX</Card>
<Card>DISCOVER</Card>
</Cards>
</P_M>
