[英]path that doesn't return a value?
我正在編寫一個應用程序,該應用程序將根據用戶輸入在平面文件中搜索特定數據,並且此應用程序即將問世。 但是,我一定是個白痴。 我已經通過此方法進行了3次檢查,但沒有看到未返回值的路徑,但是VS 2010 Express向我保證有一個。
我到底想念什么? 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]";
}
}
似乎是VS 2010的一個小故障; 關閉並重新打開該項目即可修復它。 至少我知道這不是我自己的錯誤!
