编译器告诉我“不能将类型'char'隐式转换为'bool'

Question

控制台告诉我在（28,22）它”不能隐式地将类型'char'转换为'bool'“，但在那个地方如果（ch2 ='c'） 确切的地方在'（'和'c'之间，那么这个地方在代码 中。在此先感谢您的帮助！

using System; 

public class EntranceChecking 
{ 
    public static void Main() 
    { 

     char ch1, ch2;// Input character 
     bool guess = false; // Flag that signals when the loop should terminate -- 
     // that is, when 'c' followed by 's' has been input. 
     Console.WriteLine("\nYou have before you a closed door."); 
     Console.WriteLine("You must give the correct password to enter"); 

     Console.WriteLine("Enter a character : "); 
     ch1 = Console.ReadKey().KeyChar; 


     // Insert a loop that keeps reading and processing characters 
     // until the user inputs the character 'c' followed by the 
     // character 's' (if ever). 

     while (!guess) 
     { 
      Console.WriteLine("Enter a character : "); 
      ch2 = Console.ReadKey().KeyChar; 
      if ((ch1 == 'c') && (ch2 == 's')) 
       guess = true; 
      else if (ch2 = 'c') 
      { 
       ch1 = 'c'; 
       break; 
      } 
      else 
       ch1 = Console.ReadKey().KeyChar; 
     } 

     // Open the door. 
     Console.Write("The door opens. Congratulations!"); 
    } 

}

改变这种

else if (ch2 = 'c') 

为

else if (ch2 == 'c') 

，因为如果（）需要一个布尔值，如果您使用== operartor它会返回一个布尔值
