I have created a XML method, and I am trying reference the return from xml string from CreateXML() into the WRequest() method, but I am keep experiencing the following error -- An object reference is required for the non-static field, method, or property 'MailSender.createXMLPub()'.

C#

    public static string WRequest(string URL, string method, string postData)
    {
        URL = "################";
        method = "POST";
		// how to read the xml data into this method
        postData = createXMLPub();

        string responseData = "";
        try
        {
            if (hwrequest.Method == "POST")
            {  
            }
            // Attempt to receive the WebResponse to the WebRequest.
            using (HttpWebResponse hwresponse = (HttpWebResponse)hwrequest.GetResponse())
            {
                if (hwresponse != null)
                { // If we have valid WebResponse then read it.
                    using (StreamReader reader = new StreamReader(hwresponse.GetResponseStream()))
                    {
                        reader.Close();
                    }
                }
                hwresponse.Close();
            }
        }
        catch (Exception e)
        {
            responseData = "An error occurred: " + e.Message;
        }
        return responseData;
    }

    // Updated Method - currently giving new errors.
    public static void createXMLPub(string data )
    {
        XElement xeRoot = new XElement("pub");
        XElement xeName = new XElement("name", "###");
        xeRoot.Add(xeName);
        XElement xeCategory = new XElement("category", "#####");
        xeRoot.Add(xeCategory);
		XDocument xDoc = new XDocument(xeRoot);
        xDoc.Save(Server.MapPath("products-string2.xml"));
   
        //Response.Redirect("products-string2.xml");//load web browser
        //return xDoc;

        data = xDoc.ToString();
        return data;
    }
}

New errors:
1. No overload for method 'createXMLPub' takes 0 arguments

2.An object reference is required for the non-static field, method, or property 'System.Web.UI.Page.Server.get'

Any advice, would be most welcomed. Thank you for your help and time.

And you are trying return a string from a method that is marked as a void method.

Solution 1

It looks like you are calling a non static property from a static method. You will need to either make the property static,

createXMLPub is not static method but it is called from a static method. That's the problem

Please post this as solution. Thats the correct one.

try...
public static void createXMLPub()

Hi, Apology for the late response. I had previously tried this but this approach gave me sadly more compiling errors, such as
1. No overload for method 'createXMLPub' takes 0 arguments

2.An object reference is required for the non-static field, method, or property 'System.Web.UI.Page.Server.get'

To the code below:
public static void createXMLPub(string data )
{
XElement xeRoot = new XElement("pub");
XElement xeName = new XElement("name", "###");
xeRoot.Add(xeName);
XElement xeCategory = new XElement("category", "#####");
xeRoot.Add(xeCategory);
XDocument xDoc = new XDocument(xeRoot);
xDoc.Save(Server.MapPath("products-string2.xml"));

//Response.Redirect("products-string2.xml");//load web browser
//return xDoc;

data = xDoc.ToString();
return data;
}

Please advice. Thank you.

Method createXMLPub requires String Object looking to your method
postData = createXMLPub(<your string="" object="" here="">);

1. No overload for method 'createXMLPub' takes 0 arguments

Ans: This is your method

public static void createXMLPub(string data )

you are using the above method like this

postData = createXMLPub();

where is your parameter passing in above method
so it should be like this

postData = createXMLPub("yourdata");

2. An object reference is required for the non-static field, method, or property 'System.Web.UI.Page.Server.get'

Ans: In this method you are not passing data

public static void createXMLPub(string data )

and calling this method at

public static string WRequest(string URL, string method, string postData)

like

postData = createXMLPub();

here postData is a string type and the method createXMLPub is returning string value but method signature is like void so your createXMLPub() method should be like this

public static string createXMLPub(string data )
