c# - 如何将用户输入的字符串更改为整数？

Question

For my mini-project, I can't convert the string .ReadLine input to the integer needed for guessing int number = 5;

  int user = Convert.ToInt32(Console.ReadLine);

  if (user == number){
    Console.WriteLine("You a Genius boe!!!");
  }
  else if ( user == (number - 1) ){
    Console.WriteLine("A bit Higher!");
  }
  else if ( user == (number + 1) ){
    Console.WriteLine("A bit Lower!");
  }
  else{
    Console.WriteLine("U Serious Bruh???");
  }

I think you were nearly there with your code. All you needed was a loop to encapsulate the code asking the user to keep guessing.

    int guess = 5;

    while (true)
    {
        int user;
        Console.WriteLine("Guess a number boe???");
        string input = Console.ReadLine();
        if (Int32.TryParse(input, out user))
        {
            if (user == guess)
            {
                Console.WriteLine("You a Genius boe!!!");
                Console.ReadLine();
                return;
            }
            else if (user == (guess - 1))
            {
                Console.WriteLine("A bit Higher!");
            }
            else if (user == (guess + 1))
            {
                Console.WriteLine("A bit Lower!");
            }
            else
            {
                Console.WriteLine("U Serious Bruh???");
            }
        }
        else
        {
            Console.WriteLine("You didnt entered a correct value try again!!!");
        }
    }

As pointed out Console.ReadLine() is a method, you were missing the brackets.

you can do something like this

     bool Valid = false;
    int Number;
    while(Valid == false){
      string Input = Console.Readline();
      if(int.TryParse(Input, out Number){
        Valid = true;
  if (Number == number){
    Console.WriteLine("You a Genius boe!!!");
  }
  else if ( Number == (number - 1) ){
    Console.WriteLine("A bit Higher!");
  }
  else if ( Number == (number + 1) ){
    Console.WriteLine("A bit Lower!");
  }
  else{
    Console.WriteLine("U Serious Bruh???");
  }
      }
      else{
        Console.Writeline("Not an integer, please try again.")
      }
    }
