我在.CS文件中有一个功能。我想将函数中提取的许多值返回到.aspx.cs文件（同一项目中的两个文件）
如何从以下函数返回值（.CS文件代码如下）：

我想通过倡导者，jjj，tyear，year，petitioner1，resp1，sb等......我怎么能这样做？

如果要从方法返回多个值，则需要创建一个类来执行此操作。
例如：
public class Product
{
int Id { get; set;}
string Name { get; set;}
double Value { get; set;}
}
然后当您想从方法中返回产品时：
public Product GetProduct(string Id)
{
Product product;
// load product here
return product;
}

将所有相关值封装在一个新类型中，并使您的方法返回该类型的实例。
哦，并尽量避免使用这些巨大的方法 - 它们是可读性，测试等的噩梦。
答案 2 :(得分：1)
函数只返回一个值。对多个返回值使用“out”或“ref”参数。
