1.定义
enum orientation :byte
{
north=1,
south=2,
east=3,
west=4
}
2.使用
//定义enum
orientation myOrientation = orientation.east;
System.Console.WriteLine(myOrientation);
//enum->byte
byte directionByte = (byte)myOrientation;
System.Console.WriteLine(directionByte);
//byte->enum ; 如果byte值未映射到enum中的一个值,会产生逻辑错误,但不会抛出异常;
myOrientation = (orientation)directionByte;
System.Console.WriteLine(myOrientation);
//enum->toString()
string directionStr = Convert.ToString(myOrientation);
//String->enum; 如果值不能映射为enum中的一个值,会抛异常;
myOrientation = (orientation)Enum.Parse(typeof(orientation), "north");
System.Console.WriteLine(myOrientation);
