Hi,
how can I select and change the value "Entwicklung" (bold, unterline) in this XML in C#?
Thank you
Regards

<?xml version="1.0" encoding="utf-8"?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <!-- Pfad zu log-Verzeichnis  -->
  <variable name="logDir"  value="${specialfolder:folder=ApplicationData}/BAMF/Maris/logs"/>
  <variable name="logFile" value="${shortdate}.log"/>
  <variable name="umgebung" value="Entwicklung"/>
</nlog>

推荐答案

{specialfolder：folder = ApplicationData} / BAMF / Maris / logs / >
< 变量 名称 = logFile value < span class =code-keyword> =

{specialfolder:folder=ApplicationData}/BAMF/Maris/logs"/> <variable name="logFile" value="

{shortdate} .log / >
< 变量 名称 = umgebung value = Entwicklung / >
< / nlog >

{shortdate}.log"/> <variable name="umgebung" value="Entwicklung"/> </nlog>

你可以使用Xelement类来做到这一点：

如此处所示使用ReplaceWith：

You could use Xelement class to do that:
http://msdn.microsoft.com/en-us/library/system.xml.linq.xelement_methods.aspx[^]

As shown here using ReplaceWith:

// input would be your edited XML, this is just sample data to illustrate
string input = @"<Artist Name=""Pink Floyd"">
  <BandMembers>
    <Member>Nick Mason</Member>
    <Member>Syd Barret</Member>
    <Member>David Gilmour</Member>
    <Member>Roger Waters</Member>
    <Member>Richard Wright</Member>
  </BandMembers>
  <Category>Favorite band of all time</Category>
</Artist>";

var replacement = XElement.Parse(input);
var pinkFloyd = xml.Elements("Genre")
                   .Where(e => e.Attribute("Name").Value == "Rock")
                   .Elements("Artist")
                   .Single(e => e.Attribute("Name").Value == "Pink Floyd");

pinkFloyd.ReplaceWith(replacement);
Console.WriteLine(xml);
