XML

<wd:Report_Entry>
        <wd:Cost_Center wd:Descriptor=\"8808 ECO Global Forwarding Austria\">
            <wd:ID wd:type=\"WID\">b81295748006019ec87c29edcb020044</wd:ID>

身份证收藏

var orgId = (from x in xml.Descendants(xmlNamespace + "Included_by_Organizations").Elements()
                        select x into y
                        where y.Attribute(xmlNamespace + "type").Value == "Organization_Reference_ID"
                        select y.Value);

为对象属性设置值

var costCenterValues = from cc in xml.Descendants(xmlNamespace + "Report_Entry")
                                   select new CostCenter
                                   {
                                       CostCenterId = cc.Element(xmlNamespace + "Reference_ID").Value,
                                       Name = cc.Element(xmlNamespace + "name").Value,
                                       Code = cc.Element(xmlNamespace + "code").Value,
                                       //CostCenterHierarchyId = 
                                   };

            return costCenterValues.ToList();

鉴于上面的xml，设置CostCenterHierarchyID值的最佳方法是什么？

<wd:Included_by_Organizations wd:Descriptor=\"RU7860 Europe Forwarding Overhead\">
            <wd:ID wd:type=\"WID\">b8129574800601751d8538accb023f35</wd:ID>
            <wd:ID wd:type=\"Organization_Reference_ID\">RU7860</wd:ID>
            <wd:ID wd:type=\"Custom_Organization_Reference_ID\">RU7860</wd:ID>
</wd:Included_by_Organizations>

Answer 1

解决办法

.Element(xmlNamespace + "Included_by_Organizations")
.Elements(xmlNamespace + "ID")
.Where(x => x.Attribute(xmlNamespace + "type").Value == "Organization_Reference_ID")
.FirstOrDefault().Value.ToString()
