This article introduces the knowledge of "how to load LINQ XML trees". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

LINQ XML tree loading

Through the XElement class, there are two ways to load a LINQ XML tree, one as a string and the other as a file.

1. Load as a string

In the XElement class, the XML tree is loaded into memory as a string through the static Parse () method, and an implementation code is given:

Static void Loading1 () {string xml = @ "

"; XElement element = XElement.Parse (xml); Console.WriteLine (element);}

In the above code, line 3 defines a string variable xml whose content is a XML tree. Line 5 uses XElement's static method Parse (), in which you directly enter the string variable xml that contains the XML tree to load the LINQ XML tree into memory. * output the contents of the XML tree in the console window through line 6.

two。 Load as a file

First enter the XML tree content contained in the string variable xml shown in the above code in a blank notepad file, then set the file name to "MyContactList.xml" and save it in the application "LINQtoXML" directory "\ bin\ debug".

Then, through the XElement class, the static Load () method is called to load the contents of the XML tree into memory as an external file, and an implementation code is given:

Static void Loading2 () {XElement elementFromFile = XElement.Load ("MyContactList.xml"); Console.WriteLine (elementFromFile);}

In the above code, line 3 directly calls the static Load () method in the XElement class, and directly inputs the external XML file "MyContactList.xml" containing the XML tree in this method to load the LINQ XML tree into memory, and * outputs the contents of the XML tree in the console window through line 4.
