C＃中的UInt32.GetHashCode方法与示例

UInt32.GetHashCode方法用于获取当前UInt32实例的HashCode。

Syntax: public override int GetHashCode ();

Return Value: This method returns a 32-bit signed integer hash code.

下面的程序说明了上面讨论的方法的使用：

范例1：

// C# program to illustrate the
// UInt32.GetHashCode() Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Taking UInt32 variable
        // i.e. uint data type
        uint s1 = 13224;
  
        // Getting the hash code 
        // using GetHashCode() method
        int result = s1.GetHashCode();
  
        // Display the HashCode
        Console.WriteLine("HashCode for UInt32 is: {0}",
                                                result);
    }
}

输出：

HashCode for UInt32 is: 13224

范例2：

// C# program to illustrate the
// UInt32.GetHashCode() Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        // using result() Method
        result(UInt32.MinValue);
        result(UInt32.MaxValue);
    }
  
    // result() method
    public static void result(uint val)
    {
  
        // using GetHashCode() method
        int code = val.GetHashCode();
  
        // Display the hashcode
        Console.WriteLine("HashCode for {0} is {1}",
                                        val, code);
    }
}

输出：

HashCode for 0 is 0
HashCode for 4294967295 is -1
