针对你提出的“valueerror: could not convert string to float: 'c'”问题,我将从以下几个方面进行详细解答: 确认错误产生的原因: 这个错误通常发生在尝试将非数字字符串转换为浮点数时。在这个例子中,字符串 'c' 显然不是一个数字,因此无法被转换为浮点数。 检查代码中导致错误的数据输入部分: 你需要查看...
int b=Convert.Toint32(a); 此时输出b为123 但是如果string a="123.5f"这种不会输出123,会报错 注意这里不是toint而是Toint32,因为内置类型表里是Toint32。比如想将字符串转化为float只能写成 convert.tosingle()而不是convert.tofloat() 3.string a="123"; ...
