C# CharEnumerator.MoveNext()用法及代碼示例

CharEnumerator.MoveNext()方法用於將當前CharEnumerator對象的內部索引遞增到枚舉字符串的下一個字符。

用法:

public bool MoveNext();

返回值：如果索引成功遞增，則此方法返回布爾值true，否則返回false。

以下示例程序旨在說明CharEnumerator.MoveNext()方法的使用：

示例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); 
        } 
    } 
}

輸出：

A Computer Science Portal for Geeks!

示例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); 
        } 
    } 
}

輸出：
