当试图从另一个方法输出扰码时，我得到System.Char []

Question

我发送一个单词到我的争夺方法，返回加扰的单词，但当我尝试输出单词时，我得到System.Char []。我看到另一个类似于我的线程，但他使用了.ToCharArray和.ToString，这是他的问题，我无法从中找出它。这是C＃，我仍在学习。我不想要答案。我想知道我在做什么错误，并提出解决问题的建议。 （我不知道为什么for循环显示这种方式）

Answer 1

for (int i = 0; i < scrambledWord.Length; i++) 
{ 
    display = "" + scrambledWord; 
    Graphics.DisplayOnLine(display); 
} 

应

for (int i = 0; i < scrambledWord.Length; i++) 
{ 
    display = "" + scrambledWord[i]; 
    Graphics.DisplayOnLine(display); 
} 

被替换如"" + scrambledWord将使用scrambledWord.ToString()，其返回System.Char[]（其类型名称）

OR

不久说，作为Joel Coehoorn曾建议：

Graphics.DisplayOnLine(new String(scrambledWord));
