【问题描述】：

读取这个xml文件获取程序集名称及其覆盖率小于95的，我需要读取代码覆盖率值小于95%的程序集名称，并存储该程序集对象中的名称和覆盖百分比。

  <?xml version="1.0" encoding="UTF-8"?>
    -<Root DotCoverVersion="2021.1.2" ReportType="Xml" CoveragePercent="97" TotalStatements="108" CoveredStatements="105">

    <Method CoveragePercent="100" TotalStatements="9" CoveredStatements="9" Name="Test_total():void"/>
    </Type>
    </Namespace>
    </Assembly>
    </Root>

这是xml文件。

【参考方案1】：

你可以试试下面的代码，使用XDocument来实现小于95的程序集名称和覆盖率。

   string path = "E:\\test.xml";
    XDocument doc = XDocument.Load(path);
    var result = doc.Descendants("Assembly").Where(i => Convert.ToInt32(i.Attribute("CoveragePercent").Value) < 95);
    foreach (var item in result)
    
        Console.WriteLine(item.Attribute("CoveragePercent").Value);
        Console.WriteLine(item.Attribute("Name").Value);
    

结果：

非常感谢 :)

【参考方案2】：

尝试以下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication

    public class Program
    
        const string FILENAME = @"c:\temp\test.xml";
        public static void Main(string[] args)
        
            XDocument doc = XDocument.Load(FILENAME);
            XElement xRoot = doc.Root;
            Root root = new Root() 
                DotCoverVersion = (string)xRoot.Attribute("DotCoverVersion"),
                ReportType = (string)xRoot.Attribute("ReportType"),
                CoveragePercent = (int)xRoot.Attribute("CoveragePercent"),
                TotalStatements = (int)xRoot.Attribute("TotalStatements"),
                CoveredStatements  = (int)xRoot.Attribute("CoveredStatements"),
                Level = 0
            ;

            Node.GetNodes(xRoot, null, 1);

            List<Node> lowCoverage = Root.Nodes.Where(x => x.CoveragePercent < 95).ToList();
            foreach (Node node in lowCoverage)
            
                Console.WriteLine("Name = 0, Percentage = 1", node.Name, node.CoveragePercent.ToString());
            
            Console.ReadLine();

        
    
    public class Root
    
        public string DotCoverVersion  get; set; 
        public string ReportType  get; set;

        public int TotalStatements  get; set;

        public static List<Node> Nodes = new List<Node>();

        public string Name  get; set; 
        public string TagName  get; set; 
        public Node ParentNode  get; set; 

        public static void GetNodes(XElement xParent, Node parentNode, int level)
        
            foreach (XElement child in xParent.Elements())
            
                Node newNode = new Node();
                Root.Nodes.Add(newNode);
                newNode.Name = (string)child.Attribute("Name");
                newNode.TagName = child.Name.LocalName;
                newNode.ParentNode = parentNode;
                newNode.Level = level;
                newNode.TotalStatements = (int)child.Attribute("TotalStatements");
                newNode.CoveragePercent = (int)child.Attribute("CoveragePercent");
                newNode.CoveredStatements = (int)child.Attribute("CoveredStatements");
                GetNodes(child, newNode, level + 1);
