如何从一种方法访问另一种方法？下面是AddProduct（）方法中的Dictionary Products，它包含一些数据，稍后将添加一些新数据。方法CheckProcutList（）显示所有产品，以及添加到字典中的内容。用一种方法检查产品清单是没有问题的，但它是如何单独制作的呢？换句话说，如何使产品全球化？
public static void AddProduct()
{
var Products = new Dictionary<string, decimal>()
{
{"Apple Juice", 2.5M},
{"Pizza", 16.7M},
{"Cheese Cake", 4.5M},
};
}
public static void CheckProcutList()
{
foreach (var kvp in Products) //Here is a problem
Console.WriteLine("Product name: {0}, Price: {1}", kvp.Key, kvp.Value);
SwitchMenu();
}
将产品移到addProducts方法之外，并使其保持静态。
public static Dictionary<string, decimal> Products;
public static void AddProduct()
{
Products = new Dictionary<string, decimal>()
{
{"Apple Juice", 2.5M},
{"Pizza", 16.7M},
{"Cheese Cake", 4.5M},
};
}
public static void CheckProcutList()
{
foreach (var kvp in Products) //Here is a problem
Console.WriteLine("Product name: {0}, Price: {1}", kvp.Key, kvp.Value);
SwitchMenu();
}
