C# | CharEnumerator。MoveNext()方法

原文:https://www . geeksforgeeks . org/c-sharp-charenumerator-movenext-method/

CharEnumerator。MoveNext()方法用于将当前字符枚举器对象的内部索引递增到枚举字符串的下一个字符。

语法:

public bool MoveNext();

返回值:如果索引成功递增并且在枚举字符串内，则该方法返回布尔值 true 值，否则返回 false 。

下面是说明使用字符枚举器的程序。MoveNext() 方法:

例 1:

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

class GFG {

    // Driver code
    public static void Main()
    {
        // Initialize a string object
        string str = "A Computer Science Portal for Geeks!";

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

        // Printing the string
        while (chEnum.MoveNext()) 
        {
            Console.Write(chEnum.Current);
        }
    }
}

Output:

A Computer Science Portal for Geeks!

例 2:

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

class GFG {

    // Driver code
    public static void Main()
    {
        // Initialize a string object
        string str = "Best Data Structure and Algorithms Tutorials!";

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

        // Printing the string
        while (chEnum.MoveNext()) 
        {
            if (chEnum.Current == ' ') 
            {
                Console.WriteLine();
                continue;
            }
            Console.Write(chEnum.Current);
        }
    }
}

Output:
