There is no mistake, as it compiles and runs fine on my test. I would recommend using the universl bot library instead, as it also provides you access to the source code.

My problem is solved "EZB _ezb = new EZB();" must stand before void main

But now I have this issue:

dmcs -r:EZ_B.dll bsp.cs bsp.cs(16,9): error CS0120: An object reference is required to access non-static member `HelloWorld._ezb' Compilation failed: 1 error(s), 0 warnings

in Line 16 is "_ezb.Connect("192.168.1.1");"

As you can imagine, it's difficult to assist when I only see a small fragment of the project. If you insist on moving forward with the mono library, please post your project or complete code and we'll get you running

Are you also using Linux? Which compiler do u use? How do you compile it? Thanks for your time

using System; using EZ_B;

public class HelloWorld { EZB _ezb = new EZB(); //this stands now before ""void main"

public static void Main() { Console.WriteLine("Enter IP of EZ-Robot"); string ip = Console.ReadLine(); Console.WriteLine("IP: "+ip ); Console.WriteLine("trying "+ ip); Console.WriteLine("trying to connect with " +ip);

//connecting

_ezb.Connect(ip); Console.WriteLine("connecting..."); if (_ezb.IsConnected) { Console.WriteLine("[+] EZB connected at ip: " + ip); } else { Console.WriteLine("[-] EZB NOT connected at ip: " + ip); }

} }

in simple form:

using System; using EZ_B;

public class HelloWorld { EZB _ezb = new EZB();

public static void Main()
{
    _ezb.Connect("192.168.1.1");  
}

}

console output:

patrick@patrick-X781X-X782X:~/ezrobot$ dmcs -r:EZ_B.dll bsp.cs bsp.cs(12,9): error CS0120: An object reference is required to access non-static member `HelloWorld._ezb' Compilation failed: 1 error(s), 0 warnings

This is because the MAIN() is declared as static. The error message explains it. It says, an object is required to access a non-static member, and gives you the object, which is _ezb.

An error is written text to explain what the issue is. The error says the object _ezb is non-static but is being called from a static method.

As you can see, the method Main() is static, and the variable ez_b isn't.

Either make the _ezb static, or make Main() not static. I'm not sure if you can make Main() not static, but try and let me know. Otherwise, make _ezb static.

Here's a document i found for you that discusses the difference between static and non-static declaration: http://www.c-sharpcorner.com/uploadfile/abhikumarvatsa/static-and-non-static-methods-in-C-Sharp/

Thanks for answering,

if i make the main void non static .... public void Main() .....

there is an error: error CS5001: Program bsp.exe' does not contain a static Main' method suitable for an entry point

so I think void main must be static.

Then i tried to make _ezb static:

using System; using EZ_B;

public class HelloWorld { static EZB _ezb = new EZB();

public static void Main() { Console.Clear(); Console.WriteLine("Enter IP of EZ-Robot"); string ip = Console.ReadLine(); Console.WriteLine("IP: "+ip ); Console.WriteLine("[+] trying "+ ip); Console.WriteLine("[+] trying to connect with " +ip);

//connecting

Console.WriteLine("connecting..."); _ezb.Connect(ip); Console.WriteLine("[+] connecting process finished"); Console.WriteLine("wating for result...");

if (_ezb.IsConnected) { Console.WriteLine("[+] EZB connected at ip: " + ip); }

else { Console.WriteLine("[-] EZB NOT connected at: " + ip); }

} }

it compiled

but if I execute it....

In Visual Studio under Windows it worked perfectly...

If i get this running, I will make a Tutorial on your Website to help other users
