Converting XML to string using C#

Question

I have a function as below

public string GetXMLAsString(XmlDocument myxml)
    {
        XmlDocument doc = new XmlDocument();
        doc.LoadXml(myxml);
       
        StringWriter sw = new StringWriter();
        XmlTextWriter tx = new XmlTextWriter(sw);
        doc.WriteTo(tx);

        string str = sw.ToString();// 
        return str;
    }

I'm passing an XML to this method from an another method. But in the doc.loadxml(), the system is expecting a string and since I'm passing an XML, it throws error.

How to solve this issue?

Answer 1

As Chris suggests, you can do it like this:

public string GetXMLAsString(XmlDocument myxml)
{
    return myxml.OuterXml;
}

Or like this:

public string GetXMLAsString(XmlDocument myxml)
    {

        StringWriter sw = new StringWriter();
        XmlTextWriter tx = new XmlTextWriter(sw);
        myxml.WriteTo(tx);

        string str = sw.ToString();// 
        return str;
    }

and if you really want to create a new XmlDocument then do this

XmlDocument newxmlDoc= myxml
