c# - Saving to xml file -

i have question updating data in current xml file.

for example want change radius "50"

xml file:

    <?xml version="1.0" encoding="utf-8"?> <settings>     <radius>25</radius>     <length>40</length>     <height>15</height>     <name>oks</name> </settings> 

i can read these settings code:

public void getsettings()         {             xmldocument xml = new xmldocument();             xml.load(location);              xmlnodelist xnlist = xml.selectnodes("/settings");              foreach (xmlnode xn in xnlist)             {                 tb_height.text = xn["height"].innertext;                 tb_lenght.text = xn["length"].innertext;                 tb_radius.text = xn["radius"].innertext;                 tb_name.text = xn["name"].innertext;             }         } 

not sure trying do.

but save file, can simply:

xml.save(pathtosaveto);
