为什么 DeserializeXmlNode 输出 XML 将数组元素包含在额外的标记中？

Question

我有以下 JSON 我正在转换为 XML:

{
  "root": {
    "object": [{
      "Name": "Cust1",
      "addresses": [
        [{
          "AddressLine1": "Address1",
          "AddressLine2": "Address2"
        }],
        [{
          "AddressLine1": "Address3",
          "AddressLine2": "Address4"
        }]
      ]
    }, {
      "Name": "Cust2",
      "addresses": [
        [{
          "AddressLine1": "Address1_2",
          "AddressLine2": "Address2_2"
        }],
        [{
          "AddressLine1": "Address3_2",
          "AddressLine2": "Address4_2"
        }]
      ]
    }]
  }
}

我用下面的代码把它转换成XML（根元素是在JSON转换后手动添加的）：

XmlDocument xmlDoc = JsonConvert.DeserializeXmlNode(rootJson);

输出XML如下：

<root>
<object>
    <Name>Cust1</Name>
    <addresses>
        <addresses>
            <AddressLine1>Address1</AddressLine1>
            <AddressLine2>Address2</AddressLine2>
        </addresses>
    </addresses>
    <addresses>
        <addresses>
            <AddressLine1>Address3</AddressLine1>
            <AddressLine2>Address4</AddressLine2>
        </addresses>
    </addresses>
</object>
<object>
    <Name>Cust2</Name>
    <addresses>
        <addresses>
            <AddressLine1>Address1_2</AddressLine1>
            <AddressLine2>Address2_2</AddressLine2>
        </addresses>
    </addresses>
    <addresses>
        <addresses>
            <AddressLine1>Address3_2</AddressLine1>
            <AddressLine2>Address4_2</AddressLine2>
        </addresses>
    </addresses>
</object>

问题出在 <addresses> 标签后面跟着另一个 <addresses> 标签。

Answer 1

因为你下面多了一个[和]

  "addresses": [
    [{
      "AddressLine1": "Address1",
      "AddressLine2": "Address2"
    }],
    [{
      "AddressLine1": "Address3",
      "AddressLine2": "Address4"
    }]
  ]

如果像下面那样删除多余的 [ 和 ]

  "addresses": [
    {
      "AddressLine1": "Address1",
      "AddressLine2": "Address2"
    },
    {
      "AddressLine1": "Address3",
      "AddressLine2": "Address4"
    }
  ]

你的json会是这样

{
  "root": {
    "object": [{
      "Name": "Cust1",
      "addresses": [
        {
          "AddressLine1": "Address1",
          "AddressLine2": "Address2"
        },
        {
          "AddressLine1": "Address3",
          "AddressLine2": "Address4"
        }
      ]
    }, {
      "Name": "Cust2",
      "addresses": [
        {
          "AddressLine1": "Address1_2",
          "AddressLine2": "Address2_2"
        },
        {
          "AddressLine1": "Address3_2",
          "AddressLine2": "Address4_2"
        }
      ]
    }]
  }
}

您将得到以下输出 XML

<root>
  <object>
    <Name>Cust1</Name>
    <addresses>
      <AddressLine1>Address1</AddressLine1>
      <AddressLine2>Address2</AddressLine2>
    </addresses>
    <addresses>
      <AddressLine1>Address3</AddressLine1>
      <AddressLine2>Address4</AddressLine2>
    </addresses>
  </object>
  <object>
    <Name>Cust2</Name>
    <addresses>
      <AddressLine1>Address1_2</AddressLine1>
      <AddressLine2>Address2_2</AddressLine2>
    </addresses>
    <addresses>
      <AddressLine1>Address3_2</AddressLine1>
      <AddressLine2>Address4_2</AddressLine2>
    </addresses>
  </object>
</root>
