C# | CharEnumerator。GetHashCode()方法

原文:https://www . geesforgeks . org/c-sharp-charenumerator-gethashcode-method/

GetHashCode()方法作为默认的哈希函数，返回当前对象的哈希代码。该方法继承自对象类。

语法:

public virtual int GetHashCode ();

返回值:该方法返回一个与当前对象的哈希码对应的 Int32 值。

下面是说明使用字符枚举器的程序。GetHashCode() 方法:

例 1:

// C# program to illustrate the use
// of CharEnumerator.GetHashCode()
// Method
using System;

class GFG {

    // Driver code
    public static void Main()
    {
        // Initialize a string object
        string str = "GeeksforGeeks is fun";

        // Instantiate a CharEnumerator object
        CharEnumerator chEnum1 = str.GetEnumerator();

        // Instantiate another CharEnumerator object
        CharEnumerator chEnum2 = str.GetEnumerator();

        // Printing the Hash Code of
        // both the CharEnumerator objects
        Console.WriteLine(chEnum1.GetHashCode());
        Console.WriteLine(chEnum2.GetHashCode());
    }
}

Output:

-381312627
1646495825

例 2:

// C# program to illustrate the use
// of CharEnumerator.GetHashCode()
// Method
using System;

class GFG {

    // Driver code
    public static void Main()
    {
        // Initialize two string object
        string str1 = "GeeksforGeeks is fun",
                  str2 = "C C++ Java Python";

        // Instantiate a CharEnumerator object
        CharEnumerator chEnum1 = str1.GetEnumerator();

        // Instantiate another CharEnumerator object
        CharEnumerator chEnum2 = str2.GetEnumerator();

        // Printing the Hash Code of
        // both the CharEnumerator objects
        Console.WriteLine(chEnum1.GetHashCode());
        Console.WriteLine(chEnum2.GetHashCode());
    }
}

Output:

491910500
-1775248344
