C# | Byte。GetHashCode()方法
原文:https://www . geesforgeks . org/c-sharp-byte-gethashcode-method/
此方法用于返回给定字节的哈希代码。 语法:
public override int GetHashCode ();
返回值:该方法返回当前字节的哈希码。 下面的程序说明了字节的使用。GetHashCode() 方法: 例 1:
c sharp . c sharp . c sharp . c sharp
// C# program to demonstrate
// Byte.GetHashCode Method
using System;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing val
long val = 83935;
// converting long array into bytes
byte[] bytes = BitConverter.GetBytes(val);
// getting hashcode
// using GetHashCode() method
for (int i = 0; i < bytes.Length; i++) {
// getting hash code of a single byte
int j = bytes[i].GetHashCode();
Console.WriteLine("Hashcode: {0}", j);
}
}
}
Output:
Hashcode: 223
Hashcode: 71
Hashcode: 1
Hashcode: 0
Hashcode: 0
Hashcode: 0
Hashcode: 0
Hashcode: 0
例 2:
c sharp . c sharp . c sharp . c sharp
// C# program to demonstrate
// Byte.GetHashCode Method
using System;
class GFG {
// Main Method
public static void Main()
{
check((long)8543, "long");
check((int)8543, "int");
check((byte)85, "byte");
}
// Defining the check method
public static void check(long val, string name)
{
// converting long array into bytes
byte[] bytes = BitConverter.GetBytes(val);
// getting hashcode
// using GetHashCode() method
Console.Write(name + " hashcode:- ");
for (int i = 0; i < bytes.Length; i++) {
// getting hash code of a single byte
int j = bytes[i].GetHashCode();
Console.Write("{0} ", j);
}
Console.WriteLine("");
}
// Defining the check method
public static void check(int val, string name)
{
// converting long array into bytes
byte[] bytes = BitConverter.GetBytes(val);
// getting hashcode
// using GetHashCode() method
Console.Write(name + " Hashcode: ");
for (int i = 0; i < bytes.Length; i++) {
// getting hash code of a single byte
int j = bytes[i].GetHashCode();
Console.Write("{0} ", j);
}
Console.WriteLine("");
}
// Defining the check method
public static void check(byte val, string name)
{
// converting long array into bytes
byte[] bytes = BitConverter.GetBytes(val);
// getting hashcode
// using GetHashCode() method
Console.Write(name + " hashcode:- ");
for (int i = 0; i < bytes.Length; i++) {
// getting hash code of a single byte
int j = bytes[i].GetHashCode();
Console.Write("{0} ", j);
}
Console.WriteLine("");
}
}
Output:
long hashcode:- 95 33 0 0 0 0 0 0
int Hashcode: 95 33 0 0
byte hashcode:- 85 0
