internal void Close()
{
throw new NotImplementedException();
}

internal void Open()
{
throw new NotImplementedException();
}

public static implicit operator SqlConnection(MySqlConnection v)
{
throw new NotImplementedException();
}
}

What I have tried:

internal class MySqlConnection
{
	
	public MySqlConnection(string host)
	{
	}

	internal void Close()
	{
		throw new NotImplementedException();
	}

	internal void Open()
	{
		throw new NotImplementedException();
	}

	public static implicit operator SqlConnection(MySqlConnection v)
	{
		throw new NotImplementedException();
	}
}

This is the error message which was displayed in Visual Studio 2017. Please assist me in solving this problem

System.NotImplementedException HResult=0x80004001 Message=The method or operation is not implemented. Source=App_Web_mm4tvnwn StackTrace: at MySqlConnection.Open() in c:\BIT10904\administrator.aspx.cs:line 64 at administrator.Upload_Click(Object sender, EventArgs e) in c:\BIT10904\administrator.aspx.cs:line 224

Look at your code; you have three methods which all throw NotImplementedException. So you need to replace those throw statements with the actual implementation of the methods.

Could u help to re-edit the part? Because im not certain with which coding im supposed to remove and replaced with. Sorry for the inconvenience

You have been given framework software for you to "fill in" with working code.
The idea is that the "not implemented exception" reminds you that you haven't written the code yet and makes it easy to locate the parts you need to complete.

Fill them in with the right code, and replace the throw statements is all you have to do.

BTW: C# and C++ are very different languages which share some common syntax: if you tag your questions with the wrong language, you reduce the number of the correct people who will look at it, and thus the chances of a helpful reply ...
