Question

我正在查询Xelement并尝试将字符串值转换为另一个对象

这是Xml

<Test ID="2278388" TestCompleted="2013-06-25T14:13:07.137">
<TestResult>P</TestResult> 
<TestType>
 <Name>Nursing</Name> 
 <Part1>ULE</Part1> 
 <Part2>PRI</Part2> 
</TestType>
<ExamCode>P1</ExamCode>
</Test>

使用webclient我已经将其变成了一个Xelement'Elm' 我已经弄清楚如何获得Name part1和part2 但无法弄清楚如何获得ID，Testresult，已完成或考试代码

private BssClient XMLtoBssClient()
        {
            BssClient BssC = new BssClient();


            BssC.caseType = ((wch.Elm).Descendants("TestType").Select(x => x.Element("Name").Value).FirstOrDefault()) ?? "";
            BssC.matter1 = ((wch.Elm).Descendants("TestType").Select(x => x.Element("Part1").Value).FirstOrDefault()) ?? "";
            BssC.matter2 = ((wch.Elm).Descendants("TestType").Select(x => x.Element("Part2").Value).FirstOrDefault()) ?? "";
            BssC.ExamCode = 
            BssC.ID =
            BssC.DateCompleted =

            return BssC;

    }

我用Google搜索并查看MSDN并尝试了各种各样的事情但这对我来说真的很新任何帮助非常感谢

以下代码应该有效：

private BssClient XMLtoBssClient()
    {
        BssClient BssC = new BssClient();


        BssC.caseType = ((wch.Elm).Descendants("TestType").Select(x => x.Element("Name").Value).FirstOrDefault()) ?? "";
        BssC.matter1 = ((wch.Elm).Descendants("TestType").Select(x => x.Element("Part1").Value).FirstOrDefault()) ?? "";
        BssC.matter2 = ((wch.Elm).Descendants("TestType").Select(x => x.Element("Part2").Value).FirstOrDefault()) ?? "";
        BssC.ExamCode = ((wch.Elm).Elements("ExamCode").Select(x => x.Value).FirstOrDefault()) ?? "";
        BssC.TestResult = ((wch.Elm).Elements("TestResult").Select(x => x.Value).FirstOrDefault()) ?? "";
        BssC.ID = ((wch.Elm).Attributes("ID").Select(x => x.Value).FirstOrDefault()) ?? "";
        BssC.DateCompleted = ((wch.Elm).Attributes("TestCompleted").Select(x => x.Value).FirstOrDefault()) ?? "";


        return BssC;

}

但是我建议你研究一下Xml serialization，因为它会使维护更容易，更简单。

Linq查询语法System.Xml.Linq.XElement
