Int64。C# 中的 GetHashCode 方法及示例
原文:https://www . geesforgeks . org/int 64-gethashcode-method-in-c-sharp-with-examples/
Int64。GetHashCode 方法用于获取当前 Int64 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
// Int64.GetHashCode() Method
using System;
class GFG {
// Main Method
public static void Main()
{
// Taking Int64 variable
// i.e. long data type
long s1 = 458732523;
// Getting the hash code for Int64
// using GetHashCode() method
int result = s1.GetHashCode();
// Display the HashCode
Console.WriteLine("HashCode for Int64 is: {0}",
result);
}
}
Output:
HashCode for Int64 is: 458732523
例 2:
// C# program to illustrate the
// Int64.GetHashCode() Method
using System;
class GFG {
// Main Method
public static void Main()
{
// using result() Method
result(Int64.MinValue);
result(Int64.MaxValue);
}
// result() method
public static void result(long val)
{
// using GetHashCode() method
int code = val.GetHashCode();
// Display the hashcode
Console.WriteLine("HashCode for {0} is {1}",
val, code);
}
}
Output:
HashCode for -9223372036854775808 is -2147483648
HashCode for 9223372036854775807 is -2147483648
