Question

Help converting type - cannot implicitly convert type ‘string’ to ‘bool’

I am very new to the language n I am not a good programmer. This code is giving me error:

cannot implicitly convert type int to bool.

I am not sure what I am doing wrong. Can some tell me what I am doing wrong. Any help would be appreciated n any recomendation would also help.

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

   namespace ConsoleApplication2
   {
     class mysteryVal
  {
   public const int limitOfGuess = 5;

  // Data member
    public int mystVal;
         private int numOfGuess ;
      private randomNumberMagnifier mag = new randomNumberMagnifier();

      public int randomMag(int num)
     {
        return num + mystVal;
      }

     // Instance Constructor
     public mysteryVal()
     {
        mystVal = 0;
         numOfGuess = 0;
            }

           public void game(int user)
          {
              int userInput = user;
               if (numOfGuess < limitOfGuess)
                     {
                  numOfGuess++;
                 if (userInput = mag.randomMagnifier())
                   {
                }
               }

           } 


           }
                }

Different type, but same idea. Pay attention to *where* the error is - it'll walk you straight to the problem. — , Oct 12 '12 at 03:03
I declared it as a const. Right after the class declaration. — user1730332, Oct 15 '12 at 04:34

Correct this:

if (userInput = mag.randomMagnifier())

to:

if (userInput == mag.randomMagnifier())

Here you are assigning the value in the if statement, which is wrong. You have to check the condition, for checking condition u have to use "==".
if statement returns boolean values, and because you are assigning value here, it's giving the error.

The line

if (userInput = mag.randomMagnifier())

should be

if (userInput == mag.randomMagnifier())

you should use == instead of = change: Lif(userinput = mag.randommagnifier()) for

if(userinput == mag.randommagnifier())

An if statement always contains an expression which evaluates to a boolean value. Your line

if (userInput = mag.randomMagnifier())

is not a bool which is what is causing the error. You probably meant

if (userInput == mag.randomMagnifier())

The condition

userInput = mag.randomMagnifier()

needs to be

userInput == mag.randomMagnifier()

What you have is trying to assign the userInput value and then it tries to convert the int to bool. With C# this is not possible.
