C#中数据类型的转换介绍

 //数据类型的转换
                //即string"18"==> int 18,
                //1、parse转换：将string类型转化为其他类型
                //待转数据必须要像该数据类型
                string strNumber = "18";
                int num01 = int.Parse(strNumber);
                float num02 = float.Parse(strNumber);

//2、任意类型转化为string类型
                int number = 18;
                string str = number.ToString();

//3、隐式转换:自动转换-->小范围到大范围自动转换
 
            byte b3 = 100;
            int i3 = b3;

 //4、显示转换：强制转换-->由大范围到小范围的强制转换，可能会发生精度丢失
            int i4 = 100;
            byte b4 = (byte)i4;

            byte numbe1 = 1;
            short numbe2 = 2;
            short resu =numbe1 + numbe2;

            byte numbe1 = 1;
            short numbe2 = 2;
            short resu = (short)(numbe1 + numbe2);
            //或int resu =numbe1 + numbe2;

            byte numbe1 = 1;
            byte numbe2 = 2;
            byte resu = (byte)(numbe1 + numbe2);
            //或int resu =numbe1 + numbe2;

            float numbe1 = 1;
            double numbe2 = 2;
            byte resu = (byte)(numbe1 + numbe2);
            //或double resu = numbe1 + numbe2;

           int a = 1;
            a = a + 3;
            a += 3;
 
 
            byte b = 1;
            b += 3;
            b = b + 3;
