Question

例如，从root（PBC）我想要返回一个级别（PBCVersion，ProjectName，ProjectVersion，Targets，Packages），而是使用：

foreach (XElement x in oPbcXDocument.Root.Elements())
{
    Console.WriteLine(x.Value);
}

我回来了：

PBC
1
dfcs
1102
RCM565bas_build.bat RCM565scm-00110binlogWINSIMbas_build.bat SIMscm-00110binlog
bas_package.batscm-00110PackageoutlogDFCS1102RCM565LastSuccessfulComponentsDFCS1102WINSIMLastSuccessfulComponents2

这是XML：

<?xml version="1.0" encoding="utf-8"?>
<PBC>
  <PBCVersion>1</PBCVersion>
  <ProjectName>dfcs</ProjectName>
  <ProjectVersion>1102</ProjectVersion>

    <Target>
      <TargetName>RCM565</TargetName>
      <CommandLine>bas_build.bat RCM565</CommandLine>
      <BuildEnvTypeName>scm-00110</BuildEnvTypeName>
      <RelativeOutputPath>bin</RelativeOutputPath>
      <RelativeLogPath>log</RelativeLogPath>

          <ProjectBuild>LastSuccessful</ProjectBuild>

        </BuildDependency>
      </Dependencies>
    </Package>
  </Packages>
</PBC>

我怎样才能只返回一个级别？

Answer 1

您的代码是正确的，以便将所有元素都放在Root的一个级别，但不清楚您希望获得哪种输出。我假设您希望获得上述元素的完整标记：

foreach (XElement x in oPbcXDocument.Root.Elements()) 
{ 
    Console.WriteLine(x.ToString()); 
}

Answer 2

不要使用Value属性，因为它始终包含所有后代的文本表示。根据需要处理元素。

如何从XDocument.Root中降低一级？
