C# 枚举 Equals 方法
csharpprogrammingserver side programming
要查找枚举之间的相等性,请使用 Equals() 方法。
假设我们有以下枚举。
enum Products { HardDrive, PenDrive, Keyboard};
创建两个 Products 对象并分配相同的值。
Products prod1 = Products.HardDrive; Products prod2 = Products.HardDrive;
现在使用 Equals() 方法检查相等性。它将为 True,因为两者具有相同的底层值。
示例
using System; class Program { enum Products {HardDrive, PenDrive, Keyboard}; enum ProductsNew { Mouse, HeadPhone, Speakers}; static void Main() { Products prod1 = Products.HardDrive; Products prod2 = Products.HardDrive; ProductsNew newProd1 = ProductsNew.HeadPhone; ProductsNew newProd2 = ProductsNew.Speakers; Console.WriteLine("Both are same products = {0}", prod1.Equals(prod2) ? "Yes" : "No"); Console.WriteLine("Both are same products = {0}", newProd1.Equals(newProd2) ? "Yes" : "No"); } }
输出
Both are same products = Yes Both are same products = No
