| 之间有什么区别？和||或者 C# 中的运算符？

class Program {
   static void Main(string[] args){
      int a = 4;
      int b = 3;
      int c = 0;
      c = a | b;
      Console.WriteLine("Line 1 - Value of c is {0}", c);
      Console.ReadLine();
   }
}

Value of c is 7
Here the values are converted to binary
4−−100
3−−011
Output 7 −−111

static void Main(string[] args){
   int a = 4;
   int b = 3;
   int c = 7;
   if (a > b || b > c){
      System.Console.WriteLine("a is largest");
   } else {
      System.Console.WriteLine("a is not largest");
   }
   Console.ReadLine();
}

a is largest
