好的，所以我有一些课程如下...
/// <summary>
///
/// </summary>
public class InsuredOrPrincipal
{
XElement self;
public InsuredOrPrincipal(XElement self) { this.self = self; }
public GeneralPartyInfo GeneralPartyInfo { get { return _GeneralPartyInfo ?? (_GeneralPartyInfo = new GeneralPartyInfo(self.Element("GeneralPartyInfo"))); } }
GeneralPartyInfo _GeneralPartyInfo;
public InsuredOrPrincipalInfo InsuredOrPrincipalInfo
{ get { return _InsuredOrPrincipalInfo ?? (_InsuredOrPrincipalInfo = new InsuredOrPrincipalInfo(self.Element("InsuredOrPrincipalInfo"))); } }
InsuredOrPrincipalInfo _InsuredOrPrincipalInfo;
}
/// <summary>
///
/// </summary>
public class GeneralPartyInfo
{
XElement self;
public GeneralPartyInfo(XElement self) { this.self = self; }
public NameInfo NameInfo { get { return _NameInfo ?? (_NameInfo = new NameInfo(self.Element("NameInfo"))); } }
NameInfo _NameInfo;
public Addr Addr { get { return _Addr ?? (_Addr = new Addr(self.Element("Addr"))); } }
Addr _Addr;
public string NameInfoStr
{
get { return (string)self.Element("NameInfo"); }
}
}
我尝试测试是 nameInfoStr != null 并且只是使用以下代码块测试 NameInfo != null
InsuredOrPrincipal[] coInsured = xmlDoc.Root
.Descendants("InsuredOrPrincipal")
.Select(x => new InsuredOrPrincipal(x))
.Where(ip => ip.InsuredOrPrincipalInfo.InsuredOrPrincipalRoleCd == "Coinsured")
.Where( gp => gp.GeneralPartyInfo.NameInfo != null)
.ToArray();
或 .Where(gp=> gp.GeneralPartyInfo.nameInfoStr != null
我使用 xmlDoc 作为 XDocument，我必须调用一个 InsuredOrPrincipal 数组，因为可能有很多。我需要测试名称节点是否存在于 xml 文档中。因为如果他们不这样做，那么我不想将该被保险人或原则添加到数组中。先感谢您

如果这有帮助，下面是额外的节点
public class NameInfo
{
XElement self;
public NameInfo(XElement self) { this.self = self; }
public PersonName PersonName { get { return _PersonName ?? (_PersonName = new PersonName(self.Element("PersonName"))); } }
PersonName _PersonName;
}
/// <summary>
///
/// </summary>
public class PersonName
{
XElement self;
public PersonName(XElement self) { this.self = self; }
public string Surname
{
get { return (string)self.Element("Surname"); }
set { self.Element("Surname").SetValue(value); }
}
public string GivenName
{
get { return (string)self.Element("GivenName"); }
set { self.Element("GivenName").SetValue(value); }
}
public string OtherGivenName
{
get { return (string)self.Element("OtherGivenName"); }
set { self.Element("OtherGivenName").SetValue(value); }
}
public string NickName
{
get { return (string)self.Element("NickName"); }
set { self.Element("NickName").SetValue(value); }
}
}
这是一个示例 XML
