C＃刪除反斜槓

Question

我想一個大寫字母之前刪除一個反斜槓發生

例子：

字符串以前：/G8/W7m/L/K/V/E/X/B/V/L/O/Y/M//W/At1zg==

字符串後：G8W7mLKVEXBVLOYM/WAt1zg==

String.replace沒有幫助，因爲它會刪除所有反斜槓。

Answer 1

使用正則表達式：

var s = "/G8/W7m/L/K/V/E/X/B/V/L/O/Y/M//W/At1zg=="; 
var result = Regex.Replace(s, @"/(?=[A-Z])", ""); 

Answer 2

long hand looks to be working 

function remake(){ 
    var prechange = "/G8/W7m/L/K/V/E/X/B/V/L/O/Y/M//W/At1zg=="; 
    var postChange = ""; 

    for (i=0;i<prechange.length;i++){ 

     if(prechange[i] === "/"){ 

      if(prechange[i-1] != undefined && prechange[i-1] != "/"){ 
       if(prechange[i+1] == prechange[i+1].toUpperCase()){ 
       }else{ 
        postChange += prechange[i]; 
       } 
      }else if(prechange[i-1] == "/" ){ 
       postChange += prechange[i]; 
      } 

     }else{ 
      postChange += prechange[i]; 
     } 

    } 
    console.log( prechange + " " + postChange); 

}
