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.
