使用 xml 属性创建 XML 结构 [英] Creating XML structure using xml attributes

问题描述

我正在尝试使用 xml 属性解决一个难题.问题是我们已经广泛使用了这种结构的文件，我不能偏离

I am trying to solve a puzzle with xml attributes. The problem is that we already have widely used file with this structure, from which I can't deviate

<CONFIGS>
  <CONFIG>
    <NAME>c1</NAME>
    <DB>
      <VAL1>v1</VAL1>
      <VAL2>v2</VAL2>
      <VAL3>v3</VAL3>
    </DB>
  </CONFIG>
  <CONFIG>
    <NAME>c2</NAME>
    <DB>
      <VAL1>v1</VAL1>
      <VAL2>v2</VAL2>
      <VAL3>v3</VAL3>
    </DB>
  </CONFIG>
</CONFIGS>

我已经创建了这个 c# 代码

I've created this c# code

// master class
[XmlRoot(ElementName = "CONFIGS")]
public class MyConfigs
{

    [XmlArrayItem(ElementName = "CONFIG", Type = typeof(MyConfigSchema))]
    public MyConfigSchema[] Schemas { get; set; }
}

// I should have array of these
public class MyConfigSchema
{

    [XmlElement(DataType = "string", ElementName = "NAME")]
    public string Name { get; set; }

    [XmlElement(ElementName = "DB", Type = typeof(Db))]
    public Db Config { get; set; }

    // this element is single and has subelements
    public class Db
    {

        [XmlElement(DataType = "string", ElementName = "VAL1")]
        public string Val1 { get; set; }

        [XmlElement(DataType = "int", ElementName = "VAL2")]
        public int Val2 { get; set; }

        [XmlElement(DataType = "string", ElementName = "VAL3")]
        public string Val3 { get; set; }

    }
}

// Writing 
using (var writer = new FileStream(testfile, FileMode.Create))
        {
            var ser = new XmlSerializer(typeof(MyConfigs));
            ser.Serialize(writer, confFileObj);
            writer.Close();
        }

这是我的问题 - 它写了以下输出，这几乎是我需要的，但在那里写了 <Schemas>...</Schemas> 我不能拥有.

Here is my issue - it writes the following output, which is almost what I need but in there it writes <Schemas>. . . </Schemas> that I can't have.

<代码><配置>--<架构>--<配置><NAME>c1</NAME><数据库><VAL1>v1</VAL1><VAL2>v2</VAL2><VAL3>v3</VAL3></DB></CONFIG><配置><NAME>c2</NAME><数据库><VAL1>v1</VAL1><VAL2>v2</VAL2><VAL3>v3</VAL3></DB></CONFIG>--</架构>--</CONFIGS>

有没有办法摆脱...</Schemas>?

推荐答案

看来我刚刚解决了.我以前从未见过这个，在 MSDN 上看过，因此我没有尝试.但我尝试代替这个

Looks like I just solved it. I have never seen this before, looked on MSDN, hence I didn't try it. But I tried instead of this

[XmlArrayItem(ElementName = "CONFIG", Type = typeof(MyConfigSchema))]
public MyConfigSchema[] Schemas { get; set; }

这样做

[XmlElement(ElementName = "CONFIG", Type = typeof(MyConfigSchema))]
public MyConfigSchema[] Schemas { get; set; }

我放置了 XmlElement 而不是 XmlArrayItem 并且它起作用了.我不知道可以用普通元素属性标记列表或数组.

Instead of XmlArrayItem I placed XmlElement and it worked. I didn't know one can mark List or array with plain element attribute.
