XmlElementEventArgs.LinePosition 속성

정의

네임스페이스:

System.Xml.Serialization

어셈블리:

System.Xml.XmlSerializer.dll

Source:

_Events.cs

XML 판독기가 XmlTextReader인 경우 알 수 없는 요소가 발견된 줄 번호를 가져옵니다.

public:
 property int LinePosition { int get(); };

public int LinePosition { get; }

member this.LinePosition : int

Public ReadOnly Property LinePosition As Integer

속성 값

Int32

XML 판독기가 XmlTextReader인 경우 알 수 없는 요소가 발견된 줄 번호입니다. 그렇지 않으면 -1입니다.

예제

다음 예제에서는 라는 파일에서 라는 Group 클래스를 역직렬화 UnknownElements.xml. 클래스 UnknownElement 에 해당 멤버가 없는 요소가 파일에서 발견되면 이벤트가 발생합니다. 이 예제를 시도하려면 다음 XML 코드를 UnknownElements.xml 파일에 붙여넣습니다.

<?xml version="1.0" encoding="utf-8"?>  
<Group xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">  
  <GroupName>MyGroup</GroupName>  
  <GroupSize>Large</GroupSize>  
  <GroupNumber>444</GroupNumber>  
  <GroupBase>West</GroupBase>  
</Group>
