不返回值的路徑？

我正在編寫一個應用程序，它將根據用戶輸入搜索特定數據的平面文件，並且它正在出現。但是，我一定是個白癡。我已經檢查了這個方法三次，沒有看到價值沒有返回的路徑，但VS 2010 Express確保我有一個。不返回值的路徑？

我到底在想什麼？提前致謝。

private string UserData(string[] userDB, bool forEnrollment){ 

    if (nameButton.Checked) 
    { 
     if (personBox.Text.Split(' ').Length != 2) 
     { 
      WriteDebug("ERROR: Invalid user input"); 
      return null; 
     } 
     else 
     { 
      List<string> namesFound = new List<string>(); //list of matches for the current person     


      string parsedFirst = personBox.Text.Split(' ')[0]; 
      string parsedLast = personBox.Text.Split(' ')[1]; 
      string dataSourceKey = null; 

      WriteDebug("Searching for '" + parsedFirst + " " + parsedLast + "'..."); 
      for (int d = 12; d < userDB.Length - 11; d = d + 10) //search the flat file for matches 
      { 
       string dbFirst = GetThree(userDB[d]);   //first three characters of FIRST name of current record 
       string dbLast = GetThree(userDB[d + 1]);  //first three characters of LAST name of current record 

       if (GetThree(parsedFirst) == dbFirst && GetThree(parsedLast) == dbLast) //if the name from the list is similar to the record 
       { 
        WriteDebug("Match found while comparing '" + parsedFirst + " " + parsedLast + "' to '" + userDB[d] + " " + userDB[d + 1] + "' (" + userDB[d - 1] + ")"); 
        namesFound.Add(userDB[d - 1] + ": " + userDB[d] + " " + userDB[d + 1]);  //add the person to the list of matches 
        userKey = userDB[d - 1]; 
        dataSourceKey = "\t" + userDB[d + 6]; 
       } 
      } 

      if (namesFound.Count == 0) //if no matches are found, write an error line 
      { 
       userKey = "ERROR: No matches found for '" + parsedFirst + " " + parsedLast + "'"; 
       WriteDebug("ERROR: No matches found for '" + parsedLast + " " + parsedLast + "'"); 
       return "[ERROR]"; 
      } 
      else if (namesFound.Count == 1) //if a single match is found, add the record 
      { 
       if (forEnrollment) { 
        return userKey; 
       } 
       return userKey + dataSourceKey; 
      } 
      else 
      { 
       WriteDebug("ERROR: Multiple matches found for '" + parsedFirst + " " + parsedLast + "'"); 
       /*TODO 
        * add instance of ConflictBox and populate it with namesFound 
        * prompt user to select one of the matches or skip the record entirely 
        */ 
       return "[ERROR]"; 
      } 

     } 
    } 
    else 
    { 
     /*TODO 
     * search for the student id 
     * 
     */ 
     return "[UNFINISHED CODE]"; 
    } 
}

我剛剛在VS 2010編譯你的代碼，並沒有這樣的錯誤。 –

它也不會給我這個錯誤。 VS可以通過誤導性的線路報告錯誤嗎？ – TheEvilPenguin

它應該提及一個函數名稱。你確定它是'UserData'嗎？ –

看起來是VS 2010的小故障;關閉並重新開放該項目修復它。至少我知道這不是我自己的錯誤！
