TcpClient.cs

namespace TCP_Communication
{
    class TcpClient
    {
        // ...
        public delegate void OnDataAvailable(char[] data);
        // ...
    }
}

Program.cs

using System;
using System.Collections.Generic;
using System.Text;

namespace TCP_Communication
{
    class Program
    {
        static void Main(string[] args)
        {
            // ...
            Client.OnDataAvailable = DataArrived;
            // ...
        }
        public void DataArrived(char[] newdata)
        {
            // empty for now
        }
    }
}

Error:

Quote:

'OnDataAvailable': cannot reference a type through an expression; try 'TCP_Communication.TcpClient.OnDataAvailable' instead

Yes, I tried 'TCP_Communication.TcpClient.OnDataAvailable' instead even though it is obviously wrong:

Program.cs

using System;
using System.Collections.Generic;
using System.Text;

namespace TCP_Communication
{
    class Program
    {
        static void Main(string[] args)
        {
            // ...
            TCP_Communication.TcpClient.OnDataAvailable = DataArrived;
            // ...
        }
        public void DataArrived(char[] newdata)
        {
            // empty for now
        }
    }
}

This time it gives this error message:

Quote:

'TCP_Communication.TcpClient.OnDataAvailable' is a 'type', which is not valid in the given context

I read the article in MSDN about C# delegates, but still I can't find what I'm missing.

Please help me guys, how can I fix this code?

I tried writing "public class {};" instead of "class {}", but it didn't do any good.
