如何使用C＃更改更新XML中的元素值？

Question

我有一个xml文件，想用C＃代码更新并保存目标负载的值。我的代码如下，正在尝试将XML显示如下-

var fileName = textBox1.Text;
            System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
            xmlDoc.Load(fileName);
            xmlDoc.SelectSingleNode("factoryTest/targetLoad").InnerText = "80";
            xmlDoc.Save(fileName);




<?xml version="1.0" encoding="utf-8"?>
<factoryTest xmlns="urn:gcpm">
  <targetLoad>90</targetLoad>
  <isAccepted>true</isAccepted>
  <isCertified>true</isCertified>
  <isAtRatingConditions>true</isAtRatingConditions>
  <supervisorName>Eric Larson</supervisorName>
</factoryTest>

我已经解决了这个问题。

XDocument xdoc = XDocument.Load(tFileName);
            xdoc.Elements("{urn:gcpm}factoryTest").Elements("{urn:gcpm}targetLoad").FirstOrDefault().Value = textBox2.Text;
            xdoc.Save(tFileName);
