用字串分割的時候只能分割成前四段，再多了就會提醒陣列超過索引，是因為我用utf32編碼的原因嗎
uj5u.com熱心網友回復：
把你的getstring內容發出來uj5u.com熱心網友回復：
不會循環字串數組的嗎？你那個數組是寫死的，當然會出現你這個問題uj5u.com熱心網友回復：
Getstring是串口發給緩沖區的資料uj5u.com熱心網友回復：
就算是串口讀的，也要學會寫單元測驗，或者簡單寫個測驗程式，看看你這個函式能正常作業不能，構造一個輸入，看看輸出是不是符合預期uj5u.com熱心網友回復：
與分割沒有關系 。比如字串： 1，2，3，4
分割后，只有4個陣列成員，你要訪問5個成員，當然出錯了。
所以這是因為你的字串的原因。使用前，先檢查資料格式，再使用。

取陣列賦值先判斷一下陣列的長度后再賦值。看你的寫法回傳格式一定能分出四組嗎。如果不是的話，賦值那邊就不應該寫死下標uj5u.com熱心網友回復：
額，老問題。所以還是老回答，和splite無關。和串口有關，串口從來就不是你認為的人家發“abc”你就應該收一個"abc"的，也許你get一次只收到一個"a",然后再get一次又收到一個"bc"
所以你想當然認為一定就是4個，顯然不對。
正確的做法，根據協議分割，符合協議的做你要做的事情，暫時不符合的快取到下一次判定（當然對于你目前我們只能這么說，在搞啥記憶體復用，狀態機，NIO一類的你更糊涂，還不如直接說給個大快取，符合移除并通知處理，不符合的留在那里等待下次一起判定）

根據商量好的格式進行分割，傳過來的時候一定要有"";"";"";"",如果是隨意長度的就要判斷陣列的個數，不然傳三個就會出現這種情況轉載請註明出處，本文鏈接：https://www.uj5u.com/net/131086.html
