我嘗試將插入值連接到數據庫時遇到標題錯誤。我調試的錯誤出在:使用在System.Data.dll中發生未處理的類型爲「System.ArgumentException」的異常
(VAR康恩=新的MySqlConnection(myConString))
以下是錯誤的VS2013:
System.ArgumentException了未處理的HResult = - 2147024809

連接字符串是字符指數153無效我建議你看那個連接字符串的內容,並確定哪些是在該位置。請確保您符合www.connectionstrings.com建議的內容。 – jmcilhinney
@JonH當你的代碼產生上述異常時,'myConString'的值是什麼?它可能是特定於您正在使用的參數的內容。特別是在字符153處。如果要編輯字符串以刪除敏感數據,請突出顯示字符153在哪裏。 –
@Alex:Server = xxx.xxx.xxx.xxx; PORT = 3306; DATABASE = database; Persist Security Info = No; Encrypt = True; SslMode = Required; username = admin; password = admin; 編輯:我能夠Navicat與憑據。我也加倍檢查並剪切並粘貼,以確保它不是那樣。 –
