1.Convert.ToInt是数据类型转换成int类型 2. 有三种方法toint16,toint32,toint64 int16-数值范围:-32768 到 32767 int32-数值范围:-2,147,483,648 到 2,147,483,647 int64-数值范围:-9223372036854775808 到 9223372036854775808 3.所以,按需使用吧
装箱时如果是boolean、byte、short、char、int、long则直接转换为相应的包装类的引用,对应其包装类的Value方法能获得值。 如果是float、double,如果不是NaN,装箱则转换为引用。否则将转换为一个参考r的,使得r.isNaN为true。 如果要装箱的值 是int介于-128和之间127的整数文字,或者布尔文字true或false或者介于'\u00...
