如何在XML C＃中从根部遍历到其元素？ [英] How can I traverse from the roots down to its elements in XML C#?

问题描述

<Device>
<pre><Information>
    <Model>Model name here</Model>
    <Manufacturer>Manufacturer name here</Manufacturer>
</Information>

<Output>
    <X>
        <Specifics>
            <VInput>10</VInput>
            <IInput>10</IInput>
            <VRes>0.10</<VRes>
            <IRes>0.10</IRes>
        </Specifics>
        
        <Instruction>
            <Id>"ID"</Id>
            <Values>PR0, DS0, VX{0}, AX{0}</Values>
            <MainSwitch>SW{0}</MainSwitch>

//如何在不手动搜索xml文件的情况下声明文件路径？

//如何从根遍历 - 设备 - 使用泛型类 - 获取PWID而不像示例代码那样手动声明它，因此我可以将其重用于其他。具有相同字段但值不同的xml文件。不使用标签信息，设置等



我尝试过：



string searchFile =C：\\Users\\XMLFiles \\PS.xml;

试试

{

XmlDocument document = new XmlDocument（）;

document.Load（searchFile）;

XmlElement device = document [Device];

XmlElement输出=设备[输出];

XmlElement x =输出[X];

XmlElement指令= X [指令;;

字符串值= instruction.SelectSingleNode（Values）。InnerText;

Console.WriteLine（强制）;

控制台。 ReadLine（）;

}



catch

{

throw;

}

//How can I search xml files without manually stating the filepath?
//How can I traverse from the root - Device - using a generic class - Get the PWID without manually stating it just like the sample code, so I can reuse it for other .xml files with same fields but different values. Without using the tags "information", "settings" and etc

What I have tried:

string searchFile = "C:\\Users\\XMLFiles\\PS.xml";
try
{
XmlDocument document = new XmlDocument();
document.Load(searchFile);
XmlElement device = document["Device"];
XmlElement output = device["Output"];
XmlElement x = output["X"];
XmlElement instruction = X["Instruction"];
string values = instruction.SelectSingleNode("Values").InnerText;
Console.WriteLine(force);
Console.ReadLine();
}

catch
{
throw;
}
