cannot implicitly convert type 'void' to 'string'

[megamalo22]

string codeentrd = Console.WriteLine("Enter the code for verification.", codeentrd );
                if (codeentrd.CompareTo("#2") == 0);
                {
                    block = 2;
                    continue;
                }

i don't understand why its an error please help

Console.WriteLine does not return a value, so you're trying to convert a void (returns nothing) to a string which just isnt possible. Change that line to:

string codeentrd = Console.ReadLine("Enter the code for verification.");

there is an error again 'No overload for method 'ReadLine' takes '1' arguments'

My bad, wasn't paying attention, use this:

Console.WriteLine("Enter the code for verification.");
string codeentrd = Console.ReadLine();
 

EDIT:

You'll want to check and make sure a value is provided before going any further to prevent your application from crashing. Something like this:

Console.WriteLine("Enter the code for verification.");
string codeentrd = Console.ReadLine();
 
if(!string.IsNullOrEmpty(codeentrd)
{
      //do your work here
}
else
{
     //error message here
}
