要获取此实例的哈希码,代码如下-
using System; public class Demo { public static void Main() { string[] arr = {"tom", "amit", "kevin", "katie"}; Type t1 = arr.GetType(); Type t2 = t1.GetElementType(); Console.WriteLine("Type = "+t2.ToString()); Console.WriteLine("Hash Code = "+t1.GetHashCode()); } }
输出结果
这将产生以下输出-
Type = System.String Hash Code = 9144789
让我们看另一个例子-
using System; public class Demo { enum Vehicle {Car, Bus, Bike, Airplane} public static void Main() { try { Vehicle v = Vehicle.Bike; Type type = v.GetType(); Console.WriteLine("Hash code = "+type.GetHashCode()); string[] str = type.GetEnumNames(); Console.WriteLine("GetEnumName() to return the constant name = " + str); Type type2 = type.GetEnumUnderlyingType(); Console.Write("Enum Underlying type = "+type2); Array arrObj = type.GetEnumValues(); Console.Write("Values = "+arrObj); Console.WriteLine("\nListing constants .."); for (int i = 0; i < str.Length; i++) Console.Write("{0} ", str[i]); } catch (ArgumentException e) { Console.WriteLine("不是枚举!"); Console.Write("{0}", e.GetType(), e.Message); } } }
输出结果
这将产生以下输出-
Hash code = 44757566 GetEnumName() to return the constant name = System.String[] Enum Underlying type = System.Int32Values = Demo+Vehicle[] Listing constants .. Car Bus Bike Airplane
