非静态字段，方法或属性需要对象引用 - 错误。 [英] An object reference is required for the non-static field, method, or property -- error.

问题描述

我创建了一个XML方法，我正在尝试引用从CreateXML（）的xml字符串返回到WRequest（）方法，但我一直遇到以下错误 - 非静态字段，方法或属性'MailSender.createXMLPub（）'需要对象引用。

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()'.

    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;
    }
}

新错误：

的的1。方法'createXMLPub'没有重载需要0参数



2.非静态字段，方法或属性'System.Web.UI需要对象引用.Page.Server.get '



任何建议，都会受到欢迎。感谢您的帮助和时间。

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.

推荐答案

看起来您正在从静态方法调用非静态属性。您需要将属性设为静态，

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

1。方法'createXMLPub'没有重载需要0个参数



答：这是你的方法

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

Ans: This is your method

public static void createXMLPub(string data )

你正在使用上面这样的方法

you are using the above method like this

postData = createXMLPub();

你的参数传递给上面的方法

所以它应该是这样的

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

postData = createXMLPub("yourdata");

2.非静态字段，方法或属性'系统需要对象引用.Web.UI.Page.Server.get'



答：在这种方法中你没有传递数据

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 )

并调用此方法

and calling this method at

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

喜欢

like

postData = createXMLPub();

这里postData是一个字符串类型，方法createXMLPub返回字符串v alue但方法签名就像void一样，所以你的createXMLPub（）方法应该是这样的

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 )
