    // deferred call to Close() at the end of current method 
    defer file.Close() 
    //get a new cvsReader for reading file

但輸出是這樣的： [] []

我不明白爲什麼[]出現.... 如果有人有任何想法爲什麼文件閱讀似乎是空的。

似乎閱讀過程似乎被打破。

你的主要問題是你不檢查錯誤，至少你不是的例子。如果您檢查從reader.Read（）返回的錯誤，您將知道它是ErrBareQuote，爲避免該錯誤，您必須將csv.Reader的LazyQuotes字段設置爲true。這是您的代碼的工作版本https://play.golang.org/p/3y-T1DCsp6
