问题描述

.CS文件中有一个功能.我想将在函数中获取的许多值返回到.aspx.cs文件(两个文件都在同一项目中)

I have a function in .CS file. i want to return many values fetched in the function to .aspx.cs file(both files in the same project)

如何从以下函数返回值(.CS文件代码如下):

我想通过辩护人,jjj,tyear,year,petitioner1,resp1,sb等...我该怎么办?

I want to pass advocates,jjj,tyear,year,petitioner1,resp1,sb etc... How can i do it??

推荐答案

将所有相关值封装为新类型,并使您的方法返回该类型的实例.

Encapsulate all of the related values in a new type, and make your method return an instance of that type.

哦,并尝试避免使用这样的 huge 方法-它们对于可读性,测试等都是噩梦.

Oh, and try to avoid having such huge methods - they're a nightmare for readability, testing etc.
