[英]How to copy values from XML file to variables in c#
I have an *.XMl file like this :我有一个 *.XMl 文件,如下所示:
<?xml version="1.0" encoding="utf-8" ?>
- <!-- User settings
-->
- <Settings>
<Session_File>C:\programs\Notepad++Portable\help.html</Session_File>
<Training_catalogue>C:\Windows\Cursors\aero_ew.cur</Training_catalogue>
<Users_ID>C:\Windows\_default.pif</Users_ID>
<File_with_badge_ID>C:\Windows\PFRO.log</File_with_badge_ID>
<Session_Folder>C:\Program Files</Session_Folder>
<PDF_Folder>C:\Program Files\GRETECH\GomPlayer\logos</PDF_Folder>
</Settings>
I would like put each "path" to a variable.我想把每个“路径”放到一个变量中。 For example "String user_id = C:\\Windows_default.pif" I have a following code to read an XML file.例如“String user_id = C:\\Windows_default.pif”我有以下代码来读取 XML 文件。
//Read values from xml file
XElement xelement = XElement.Load("settings.xml");
IEnumerable<XElement> employees = xelement.Elements();
// Read the entire XML
foreach (var employee in employees)
{
Maybe in this place I have to write some code
}
Please help me请帮我
You could use a Dictionary<string,string>
in this case which keys would be element names and values are paths:在这种情况下,您可以使用Dictionary<string,string>
,其中键是元素名称,值是路径:
var settings = XDocument.Load("settings.xml").Root
.Elements()
.ToDictionary(x => x.Name, x => (string)x);
Then you can access each path by it's element name.For example: settings["Users_ID"]
will return C:\\Windows\\_default.pif
然后你可以通过它的元素名称访问每个路径。例如: settings["Users_ID"]
将返回C:\\Windows\\_default.pif
If those are static fields in the XML, you can serialize to a class using DataContractSerializer (or XMLSerializer)...如果这些是 XML 中的静态字段,则可以使用 DataContractSerializer(或 XMLSerializer)将其序列化为类...
using System.Runtime.Serialization;
using System.IO;
(also need to add the reference to System.Runtime.Serialization) (还需要添加对 System.Runtime.Serialization 的引用)
