C# Char.GetHashCode()用法及代码示例

此方法用于返回此实例的哈希码。

用法:

public override int GetHashCode ();

返回值：此方法返回32位有符号整数哈希码。

以下程序说明了Char.GetHashCode()方法的使用：

示例1:

// C# program to demonstrate 
// Char.GetHashCode() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // declaring and initializing char 
        char ch1 = 'B'; 
  
        // checking condition 
        // using Equals() Method 
        int val = ch1.GetHashCode(); 
  
        // Display Hashcode 
        Console.WriteLine("Hashcode :- {0}", val); 
    } 
}

输出：

Hashcode :- 4325442

示例2:

// C# program to demonstrate 
// Char.GetHashCode() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // calling hash() Method 
        hash('a'); 
        hash('b'); 
        hash('c'); 
        hash('x'); 
        hash('y'); 
        hash('z'); 
    } 
  
    // Defining hash() Method 
    public static void hash(char ch) 
    { 
        // checking condition 
        // using Equals() Method 
        int val = ch.GetHashCode(); 
  
        // Display Hashcode 
        Console.WriteLine("Hashcode of " + ch + 
                                " :- {0}", val); 
    } 
}

输出：

Hashcode of a :- 6357089
Hashcode of b :- 6422626
Hashcode of c :- 6488163
Hashcode of x :- 7864440
Hashcode of y :- 7929977
Hashcode of z :- 7995514
