*.parse() sbyte——>long 和float——>decimal 注意:没有string.Pause() 三.Int.TryParse(string s , out int result) 该方式也是将数字内容的字符串转为int类型,但是该方式比int.Parse优越的地方,就是它不会出现异常。如果转换成功该函数返回true,如果转换失败该函数返回false。很明显,最后一个参数为输出值...

代码如下：class Program { static void Main(string[] args) { double datax = 2356987.2156;//声明double类型datax int datay = Convert.ToInt32(datax);//使用convert关键字进行转换 Console.WriteLine(datay);//输出整型变量datay Console.ReadLine(); } }结果与上例一样：...

值类型: int、char、float… 值类型还可以是结构类型和枚举类型。 引用类型:在c#中所有的类都是引用类型,包括接口;内置的引用类型有:object、dynamic 和 string: ·对象(Object)类型:是 C#中所有数据类型的终极基类,可以被分配任何其他类型,但需要先进行类型转换。 当一个值类型转换为对象类型时,则被称为装箱;另...
