1.C#学习--基本语法

 

1.数组：
  int[] myInts = {5,10,15};
  bool[][] myBools = new bools[2][];
  myBools[0] = new bool[2];
  myBools[1] = new bool[1];
  double[,] myDoubles = new double[2,2];
  string myStrings = new string[3];
  Console.WriteLine("myInts[0]:{0},myInts[1]:{1},myInts[2]:{2}",myInts[0],myInts[1],myInts[2]);
  myBools[0][0] = true;
  myBools[0][1] = false;
  myBools[1][0] = true;

  myDoubles[0,0] = 3.147;
  myDoubles[0,1] = 7.157;
  myDoubles[1,1] = 2.117;
  myDoubles[1,0] = 56.00138917;
  Console.WriteLine("myDoubles[0,0]:{0},myDoubles[0,1]:{1},myDoubles[1,1]:{2},myDoubles[1,0]:{3}",myDoubles[0,0],myDoubles[0,1],myDoubles[1,1],myDoubles[1,0]);

2.选择语句：
2.1.if语句：
  if(myInt!=0){
  Console.WriteLine("your number {0} is equal to zero." ,myInt);
  }

  if(myInt<0){
  Console.WriteLine("your number {0} is bigger than zero." ,myInt);
  }
  else{
  Console.WriteLine("your number {0} is less than zero." ,myInt);
  }

  if(myInt > 0 && myInt <=20){
  Console.WriteLine("your number {0} is bigger than zero." ,myInt);
  }
  else if(myInt != 0 ){
  Console.WriteLine("your number {0} is equal to zero." ,myInt);
  }
  else {
  Console.WriteLine("your number {0} is less than zero." ,myInt);
  }
