C# typeof 与 示例的GetType()

本文主要是介绍C# typeof 与 示例的GetType()，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

创建两个类

namespace ConsoleApp1;public interface IBagItem
{public uint UId { get; set; }
}public class BagItem : IBagItem
{public uint UId { get; set; }
}public class DreamIslandBagItem : IBagItem
{public uint UId { get; set; }
}

测试 

namespace ConsoleApp1;public class TypeOfTest
{public static void Test(){var typeOfTest = new TypeOfTest();{IBagItem bagItem  = new BagItem();typeOfTest.TypeOf(bagItem);}Console.WriteLine("-------------------------");{IBagItem bagItem  = new DreamIslandBagItem();typeOfTest.TypeOf(bagItem);}Console.WriteLine("-------------------------");{BagItem bagItem  = new BagItem();typeOfTest.TypeOf(new List<BagItem>(){bagItem});}Console.WriteLine("-------------------------");{DreamIslandBagItem bagItem  = new DreamIslandBagItem();typeOfTest.TypeOf(new List<DreamIslandBagItem>(){bagItem});}/***ConsoleApp1.IBagItemIBagItem                      ConsoleApp1.BagItem           BagItem                       -------------------------     ConsoleApp1.IBagItem          IBagItem                      ConsoleApp1.DreamIslandBagItemDreamIslandBagItem            -------------------------     ConsoleApp1.BagItem           BagItem                       ConsoleApp1.BagItem           BagItem                       -------------------------     ConsoleApp1.DreamIslandBagItemDreamIslandBagItem            ConsoleApp1.DreamIslandBagItemDreamIslandBagItem */}public void TypeOf<T>(T t) where T : IBagItem{Console.WriteLine(typeof(T).FullName);Console.WriteLine(typeof(T).Name);Console.WriteLine(t.GetType().FullName);Console.WriteLine(t.GetType().Name);}public void TypeOf<T>(List<T> list) where T : IBagItem{Console.WriteLine(typeof(T).FullName);Console.WriteLine(typeof(T).Name);Console.WriteLine(list[0].GetType().FullName);Console.WriteLine(list[0].GetType().Name);}
}

如果 入参是 单个 T则：

typeof 输出 指向示例的类型 也就是 IBagItem

GetType() 输出 源类型

如果入参是List<T>则：

typeof 、GetType()  都 输出 源类型
