How to save the value of the string variable to an .xml file?

I can't write the value of a string variable using XElement to an .xml file.

I tried use System.IO: XDocument, XElement

code.cs:

string variable ="sth";
XDocument xml_cip_c1 = new XDocument(
    new XComment("document"),
    new XElement("new root"),
    new XElement("name", variable)
);

result.xml:

<!--document-->
<new root>
    <name />
</new root>

I use method from first post,

code .cs:

  private void sb_button_click(object sender, RoutedEventArgs e)
        {
         variable1 = przycisk.Text;
         name_of_file_xml.Save(path_of_file);
        }

        static string variable1 ="sth";

I must use static var because it requires XAttribute from me.

I must use string with value, because if I declare string outwith value:

static string zmienna1 = null;

System.ArgumentNullException: 'The value cannot be zero.

code .cs:

Parameter name: value '
XDocument name_of_file_xml = new XDocument(
            new XComment("document"),
            new XElement("root",
                new XElement("name", new XAttribute ("name2", variable1 ))
                )
            );

In my project I would like to have a variable without value, is it possible?

because It don't assign the variable from button.text to me but the one set at the beginning

Here you are Sir. Use Value property:

var yourVariable = "ABC";
XDocument xml_cip_c1 = new XDocument(
    new XComment("document"),
    new XElement("new_root",
    new XElement("name") { Value = yourVariable}));

This will produce the following output:

<?xml version="1.0" encoding="utf-8"?>
<!--document-->
<new_root>
  <name>ABC</name>
</new_root>

But if you would like to add Attribute to your xml element, use the following code that uses XAttribute:

XDocument xml_cip_c1 = new XDocument(
    new XComment("document"),
    new XElement("new_root",
    new XElement("name", new XAttribute("name", yourVariable))));

Then you will get the following xml file:

<?xml version="1.0" encoding="utf-8"?>
<!--document-->
<new_root>
  <name name="ASD" />
</new_root>

try this,

.cs Code

XmlWriterSettings settings = new XmlWriterSettings();  
settings.Indent =true;  
settings.IndentChars = ("    ");  
settings.CloseOutput = true;  
settings.OmitXmlDeclaration =true;                  
using (XmlWriter writer = XmlWriter.Create("FileName.xml", settings))  
{  

    writer.WriteStartElement("newroot");  
    writer.WriteElementString("name", "ABC");  
    writer.WriteEndElement();  
    writer.Flush();  
}

Result => XML File

<?xml version="1.0" encoding="utf-8" ?>
<newroot>
   <name>ABC</name>
</newroot>
