根據分隔符的號碼建立一個字符串

Question

在這裏我想根據分隔符的號碼來建立一個字符串。 我的方案， ListOfWords是ABC | EFG然後建設者爲1/2，但在myone它只顯示1

我的C＃代碼是

var ListOfWords = "ABC|EFG"; 
var noOfOfSeperators = ListOfWords.Count(f => f == '|'); // in here it shows me 1 
StringBuilder builder = new StringBuilder(); 
for (int i = 1; i <= noOfOfSeperators; i++) { 
    builder.Append(i).Append("/"); // i want to show the final result if this is 1/2 
} 

Answer 1

var ListOfWords = "ABC|EFG|HIJ"; 

var noOfOfSeperators = ListOfWords.Count(f => f == '|'); 

StringBuilder builder = new StringBuilder(); 
for (int i = 0; i <= noOfOfSeperators; i++) 
{ 
    if(builder.Length>0) 
    { 
     builder.Append("/"); 
    } 
    builder.Append(i+1); 
} 

var newString = builder.ToString(); 

OUTPUT：

1/2/3
