在C＃控制台中創建查詢（Visual Studio 2013）

Question

您好，當我創建querygenerate分配美元時，每個人都會出錯我該如何解決

query = "INSERT INTO Question(Image,AnswerA,AnswerB,AnswerC,AnswerD,CorrectAnswer)"
+ $"VALUES("{name}","{answerList[0]}","{answerList[1]}","{answerList[2]}","{answerList[3]}","{name}");";

Error 1 Unexpected character '$' 
Error 2 Invalid expression term '' 
Error 3 ; expected

Answer 1

這應該是創建該腳本的正確方法

var query = $"INSERT INTO Question(Image,AnswerA,AnswerB,AnswerC,AnswerD,CorrectAnswer) VALUES('{name}','{answerList[0]}','{answerList[1]}','{answerList[2]}','{answerList[3]}','{name}');";

就像我們經常說的那樣，我們（社區）強烈建議您使用參數化查詢 。

Answer 2

 query ="INSERT INTO Question(Image,AnswerA,AnswerB,AnswerC,AnswerD,CorrectAnswer)" + "VALUES("+name+","+answerList[0]+","+answerList[1]+","+answerList[2]+","+answerList[3]+","+name+");";
