输入的字符串格式不正确-为什么我得到这个? [英] input string was not in a correct format - Why am I getting this?

问题描述

在对某些库进行编码时，我的字符串格式遇到了一些错误.
我真的不知道如何解决这个问题，或者关于字符串格式化的任何事情.

我的代码:

While coding some libraries I ran into some errors with my string format.
I don''t really know how to solve this, or anything about string formatting.

My Code:

public float getMeleeCB(float attk, float str, float def, float hp, float pray)
        {
            return (Convert.ToSingle((double)Convert.ToDecimal("0.3f") * (1.3 * (attk + str) + def + hp + (.5 * pray))));
            //example of use: string test = "Melee Combat Level: "+getMeleeCB(60,53,58,53,47).ToString();
        }

运行时错误消息:
未处理Format-Exception-输入字符串的格式不正确

Run-Time Error Message:
Format-Exception was unhandled - input string was not in a correct format


How do I format it to work the way I set it up?

推荐答案

附加调试器，您将发现某些参数不是正确的浮点值" .

您应该使用 TryParse [

Attach a debugger and you will find that some of your parameters isn''t a correct float value.

You should use TryParse[^] if you are not sure about that the inputs are validated.

Hope this helps!

这部分将始终抛出异常:Convert.ToDecimal("0.3f"). 0.3f 是编译器可以识别的，但不应在代码中使用.其他内容似乎还可以.

This part will always throw an exception: Convert.ToDecimal("0.3f"). The 0.3f is something the compiler recognizes, but should not be used in the code.Other stuff seems to be ok.
