字符串驗證 - 用do while循環

Question

我可以用一個do while環和正則表達式驗證字符串輸入，因此該字符串被拒絕時，一個數字是內部與[:alpha:]

Console.Write("Please Input The student First name/To cancel enter END> "); 
StFName[count] = Console.ReadLine(); 
do 
{ 
     Console.Write("Please Input The student First name/To cancel enter END> "); 
     StFName[count] = Console.ReadLine(); 
} while (StFName =! "[:alpha:]"); 

這是我的夢想場景

Answer 1

do { 
    Console.Write("Please Input The student First name/To cancel enter END> "); 
    StFName[count] = Console.ReadLine(); 
} while (Regex.IsMatch(StfName[count], "\\d+")); 

任何具有數字字符的字符串都將無法驗證。

另外，如果你想非字母數字字符（空格開）也失敗了，你應該使用下面的正則表達式：

do { 
    Console.Write("Please Input The student First name/To cancel enter END> "); 
    StFName[count] = Console.ReadLine(); 
} while (!Regex.IsMatch(StfName[count], "[a-zA-Z\\s]+")); 

Answer 2

嘗試類似：

Console.Write("Please Input The student First name/To cancel enter END> "); 
StFName[count] = Console.ReadLine(); 
do 
{ 
     Console.Write("Please Input The student First name/To cancel enter END> "); 
     StFName[count] = Console.ReadLine(); 
} while (!Regex.IsMatch(StfName[count], "[[:alpha:]]"));
