推荐答案

哪个部分让您感到困惑?您可以使用double.tryparse从文本框中获取双精度，并使用结果上的tostring方法获取第三个文本框的字符串

Which part is confusing you ? You can use double.tryparse to get doubles out of the text box and the tostring method on the result to get a string for the third textbox

您实际上应该阅读Microsoft的文档，它们始终给出用法示例:

You should reallyt read the documentation from Microsoft, they always give examples of usage:

如果您确实需要将理性数字相乘，则必须实现一个表示此类数字的类.您可以看看这篇CodeProject文章:有理数-.NET 4.0版本(理性计算1) [ ^ ].

If you really need a multiplication of rational numbers then you have to implement a class representing such numbers. You may have a look at this CodeProject article: Rational Numbers - .NET 4.0 Version (Rational Computing 1)[^].
