using System.Text;

public double distance;

int myDirection = -1;
double myDistance;

Console.WriteLine("Select a direction:");

myDist
这一步没有必要赋初值
因为第一次使用时是赋值使用，不会出现问题
myDirection = Convert.ToInt32(Console.ReadLine());
只是赋予一个初始值防止编译出错而已，楼主大可不必耿耿于怀。。。。
初始值,程序一开始时myDirection 的状态
其实,int myDirection;就这样不声明也是可以的只是不声明的话值为0

楼上正解
