Int32。C# 中的 GetHashCode 方法及示例
原文:https://www . geesforgeks . org/int 32-gethashcode-method-in-c-sharp-with-examples/
Int32。GetHashCode 方法用于获取当前 Int32 实例的 HashCode。
语法:public override int GetHashCode()；
返回值:这个方法返回一个 32 位有符号整数哈希码。
以下程序说明了上述方法的使用:
例 1:
// C# program to illustrate the
// Int32.GetHashCode() Method
using System;
class GFG {
// Main Method
public static void Main()
{
// Taking Int32 variable
int val = 32523;
// Getting the hash code for Int32
// using GetHashCode() method
int result = val.GetHashCode();
// Display the hashcode
Console.WriteLine("HashCode for Int32 is: {0}",
result);
}
}
Output:
HashCode for Int32 is: 32523
例 2:
// C# program to illustrate the
// Int32.GetHashCode() Method
using System;
class GFG {
// Main Method
public static void Main()
{
// using result() Method
result(Int32.MinValue);
result(Int32.MaxValue);
}
// result() method
public static void result(int val)
{
// using GetHashCode() method
int code = val.GetHashCode();
// Display the hashcode
Console.WriteLine("HashCode for {0} is {1}",
val, code);
}
}
Output:
HashCode for -2147483648 is -2147483648
HashCode for 2147483647 is 2147483647
