在C#中获取此实例的哈希码
要获取此实例的哈希码，代码如下-
示例
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
示例
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
