当我尝试删除取决于IDtextbox.text移动元素，而不是在XPath表达式静态值它不执行

我在Visual Studio 2010，C＃语言使用的是Windows应用程序

我需要两架E xamples： 1-取决于父元素内的元素。 2-根据父元素的属性，确保属性不是整数值，它是代码。注意：我已经搜索了很多网站，并查看了多个解决方案，没有人提及在XPath表达式中使用控制值。

使用XML LINQ是在这种情况下，比的XPath更好

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Xml; 
using System.Xml.Linq; 

namespace ConsoleApplication1 
{ 
    class Program 
    { 
     const string FILENAME = @"c:\temp\test.xml"; 
     static void Main(string[] args) 
     { 
      XDocument doc = XDocument.Load(FILENAME); 

      List<XElement> mobiles = doc.Descendants("Mobile").ToList(); 

      mobiles = mobiles.Where(x => (string)x.Element("FullName") != "Galaxy S-4").ToList(); 

      mobiles = mobiles.Where(x => (string)x.Attribute("RegDate") != "26/05/2017").ToList(); 

      doc.Descendants("Mobiles").FirstOrDefault().ReplaceWith(new XElement("Mobiles", mobiles)); 
     } 
    } 
}

非常感谢，但你给我一个例子，使用静态值而非动态（IDTXTBX.Text），并用ReplaceWith而不是删除我改变它为这种形状，但仍然不工作，它rem ove everything mobiles = mobiles.Where（x =>（string）x.Element（“ID”）== ID）.ToList（）; 使用此代码它必须删除第一个，如果我更改ID属性元素内移动节点 – ControllerSYR

mobiles = mobiles.Where（x =>（string）x.Element（“ID”）== ID）.ToList（） ; 这里的ID是一个字符串变量 – ControllerSYR

谢谢，Mr.jdweng 我用这个代码解决问题 XDocument doc = XDocument.Load（@“Mobiles.xml”）; 列表 mobiles = doc.Descendants（“Mobile”）。ToList（）; // mobiles = mobiles.Where（x =>（string）x.Element（“ID”）== ID）.ToList（）; mobiles = mobiles.Where（x =>（string）x.Attribute（“ID”）== ID）.ToList（）; doc.Descendants（“Mobile”）。FirstOrDefault（）。ReplaceWith（）; 此致敬礼 – ControllerSYR

感谢，Mr.jdweng 我解决这个问题，此代码

XDocument doc = XDocument.Load(@"Mobiles.xml"); 
List<XElement> mobiles = doc.Descendants("Mobile").ToList(); 
//mobiles = mobiles.Where(x => (string)x.Element("ID") == ID).ToList(); 
mobiles = mobiles.Where(x => (string)x.Attribute("ID") == ID).ToList(); 
doc.Descendants("Mobile").FirstOrDefault().ReplaceWith();
