Question

有人可以告诉我如何运行遍历每个元素的foreach周期Person

我有此代码用于加载，但doc1未填充数据

  XDocument doc = XDocument.Load(path);
  foreach (var doc1 in doc.Descendants("Person"))

XML看起来像这样

<Report xmlns="http://askmk/ask/Report">
    <ReportTypeId>5</ReportTypeId>
    <BankId>111</BankId>
    <ReferenceNo>1</ReferenceNo>
    <ReferenceNoReporter />
    <DateCreated>2017-01-31T01:50:44.0000000+01:00</DateCreated>
    <DataFromDate>2017-01-27T12:00:00.0000000+01:00</DataFromDate>
    <DataToDate>2017-01-27T12:00:00.0000000+01:00</DataToDate>
    <PersonList>
<Person xmlns="http://askmk/ask/ReportTypes">
        <PersonObjectId>111</PersonObjectId>
        <CellPhoneNo>111      </CellPhoneNo>
        <DateOfBirth>1985-03-18</DateOfBirth>
        <Email />
        <EMBG>111111</EMBG>
        <IsResident>1</IsResident>
        <FirstName>xxx</FirstName>
        <GenderTypeId>3</GenderTypeId>
        <LastName>xxx</LastName>
        <PhoneNo />
        <PlaceOfBirth />
        <IdDocumentList>
          <IdDocument>
            <IdDocumentTypeId>1</IdDocumentTypeId>
            <PlaceOfIssue>.                                       </PlaceOfIssue>
            <IdNo>1111</IdNo>
          </IdDocument>
        </IdDocumentList>
      </Person>
<Person xmlns="http://askmk/ask/ReportTypes">
        <PersonObjectId>1111</PersonObjectId>
        <CellPhoneNo>11111      </CellPhoneNo>
        <DateOfBirth>1969-03-28</DateOfBirth>
        <Email />
        <EMBG>1111</EMBG>
        <IsResident>1</IsResident>
        <FirstName>xxx</FirstName>
        <GenderTypeId>3</GenderTypeId>
        <LastName>xxx</LastName>
        <PhoneNo />
        <PlaceOfBirth />
        <IdDocumentList>
          <IdDocument>
            <IdDocumentTypeId>2</IdDocumentTypeId>
            <PlaceOfIssue>xxxx                     </PlaceOfIssue>
            <IdNo>1111</IdNo>
          </IdDocument>
        </IdDocumentList>
      </Person>
    </PersonList>
</Report>

我知道这很简单，但我对这个c＃不熟悉，这就是我要问的原因。

Answer 1

问题是您忘记了命名空间：

XDocument doc = XDocument.Load(path);
XNamespace ns = "http://askmk/ask/ReportTypes";
foreach (var doc1 in doc.Descendants(ns + "Person"))
{
    //TODO
}

有关更多信息，请查看：

@Alexander指出+是XNamespace.Addition operator。

您可以反序列化xml，以获取包含IEnumerable of Person对象的Report类型的对象。那么你可以遍历IEnumerable of Person。

您可以通过复制剪贴板中的xml来获取Report类型的对象，转到visual studio =＆gt;编辑=＆GT; paste spacial =＆gt;将xml粘贴为类。

这将为您创建一个课程。

课程计划 {

    static void Main(string[] args)
    {
         var path = "path to xml" or stream which contains your xml.


        XmlSerializer xs = new XmlSerializer(typeof(Report));


        using (StreamReader rd = new StreamReader(path))
        {
            var result = (Report)xs.Deserialize(rd);
            foreach(var p in result.Person)
                    { //TODO
                   }
        }



            Console.ReadLine();


    }
}
