Question

我正在使用反射按对象列表排序。我想在嵌套对象的属性上排序此列表。这是获取列表的代码，并且对列表进行排序

List<DocumentModel> documentList;

    if (contractid == -1)
        documentList = helpsi.framework.core.CustomerProvider.DocumentModel.getAllDocumentModelListByCustomer(custid, custtypeid);
    else
        documentList = helpsi.framework.core.CustomerProvider.DocumentModel.getAllDocumentModelListGridByContract(contractid);

    if (sord.Equals("asc")) documentList = documentList.OrderBy(x => x.GetType().GetProperty(sidx.ToUpper()).GetValue(x, null)).ToList();
    else documentList = documentList.OrderByDescending(x => x.GetType().GetProperty(sidx.ToUpper()).GetValue(x, null)).ToList();

DocumentModel对象具有一个DocumentModelType属性，该属性包含DocumentStateDesc字符串属性。我可以使用反射通过DocumentTypeDesc属性对列表进行排序吗？我可以在sidx参数中使用什么？谢谢

Answer 1

您应该在<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>子句中使用x => x.DocumentModelType.GetType().GetProperty(sidx.ToUpper()).GetValue(x.DocumentModelType, null)。正如您提到要在此列上订购时，此处OrderBy应该是sidx。

完整的代码如下所示。

DocumentStateDesc

Answer 2

一个快速而肮脏的解决方法是在父类中引入属性，而该父类仅返回另一个属性的属性值。只是不给它分配XmlElement属性。如果这些类是自动生成的，则不能更改它们，但是它们可能被声明为partial，然后可以在其他类定义中添加此新属性。

public string DocumentModelType_DocumentStateDesc { get => DocumentModelType.DocumentStateDesc; }

但是，如果您想为具有多个子属性的多个属性提供通用解决方案，则需要某种路径。您可以在诸如String.Split或sidx这样的定界符上'\' '.'，使用递归，然后OrderBy路径中的最后一项。

嵌套对象属性上的C＃OrderBy
