我有Class1的常量。在Class2中，Class1的两个实例由用户创建和初始化。我如何在程序中使用这些实例（它们的值由用户使用）？
我已经搜索了问题，但没有找到任何相关的帖子。
包含变量的Class1：
namespace project1
{
public class Class1
{
public int var1;
public double var2;
}
}
Class2，其中初始化了Class1的两个实例：
namespace project2
{
public class Class2
{
public void Method2_1()
{
var constants1 = new project1.Class1
{
var1 = 1,
var2 = 1.1
};
}
public void Method2_2()
{
var constants2 = new project1.Class1
{
var1 = 2,
var2 = 2.2
};
}
}
}
我要在其中使用Class1的两个初始化实例的程序：
namespace Project3
{
class Program
{
static void Main(string[] args)
{
//How can I use two instances "constants1" and "constants2" of Class1, separately, which are initialized in Class2 !?
}
}
}
感谢您的时间。
