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：...

*.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,...

MessagePack for C# is also optimized for String Key. First of all, it do not decode UTF8 byte[] to String for matching with the member name, it will look up the byte[] as it is(avoid decode cost and extra allocation).And It will try to match each long type (per 8 character, if...
The char type is implicitly convertible to the following integral types: ushort, int, uint, long, ulong, nint, and nuint. It's also implicitly convertible to the built-in floating-point numeric types: float, double, and decimal. It's explicitly convertible to sbyte, byte, and short integra...
