Are you creating a user control?

g@urav123 3-Jul-14 1:15am

it is control class which is inherited and created and user define control

Member 10579673 3-Jul-14 1:08am

are you associating method call with any Control?like button or something?

Create object of this class and Access method with object name.

1.Because your demo() method is public and your class MapPanel is private you cannot access this method from outside of this class. In order to can have access to it, first you have to make your class public, then by using an object of type MapPanel you will have access to it.

2.If you want to have access to your demo() method from this class without to use an object of type MapPanel you have to declare your demo() method public static , but also in this 2nd case first you have to make your class public.

Yes i have made it public also but it is not allowing me to call the method by creating the object of it from outside anywhere.

Raul Iloc 3-Jul-14 7:09am

I saw some code in your comment to "Solution3", so if this is your code you have to make "public" also your "MapPanelOuter" class!
Sp both classes must be public like this: "public class MapPanelOuter {...}"

Solution 3

you can call this class Mappanel out side the class
if the following class is inner class then you can create an object for inner class in parent class and you can also call inner class method using Mappanel object

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace ConsoleApplication3
{
class MapPanelOuter
{
public MapPanelOuter()
{
MapPanel mp = new MapPanel();
mp.demo();
}

private class MapPanel : Control
{
public void demo()
{
Console.WriteLine("Called MapPanel Demo Method");
}
}

}
}

and in another class i have called like this

using System.Text;

namespace ConsoleApplication3

this thing is not working i have already tried this thing..

Solution 5

You can't call a method on a field outside of a method.

sample code:
class 1:

C#

public class Test
   {
       public Test()
       {

       }
       public void Sum()
       {
           Console.Write("hello");
       }
       public string sayhello()
       {
           return "hello";
       }
   }

class2:(creating object and calling methods)

C#

public class testclient
   {
       Test obj = new Test();

       void rt()
       {
           obj.Sum();
           obj.sayhello();
       }
   }

This thing didn't worked for me

Pravuprasad 3-Jul-14 9:06am

why it didn't work for you? What was the error?

g@urav123 4-Jul-14 8:08am

it is not able to create the object.

Solution 6

Is possible to create the object for that class (MapPanel) in some other class?.if not possible to access this class to other class means you have to check the MapPanel class property(right click className in solution explorer) called
"Build Action " set to "Compile".i think now you may able to access this class.

i didn't created different class file for the MapPanel in the Project. it is in other Class file.

Solution 1

I think u can not create a class because of it is private class.
