所以, 第二行会报错的原因是因为在 double 的类型声明中, 没有定义 double(int a)的这种函数。 而至于Convert.ToDouble(str); 或者说TryParse, 其实现原理又与上面的不太一致, 他们的内部是实现了一个叫做 IConvertable的接口, 在MSDN, 会发现在很多基础类型的声明中, 都实现了这个叫做IConvertible的接口, 具...
Through the “ToDouble()” function we can convert a string to double. For this purpose, simply initialize a string in code and then use the “Convert.ToDouble()” function and put the name of that string inside the brackets of this function and then print the required output. It will ...
