您好我正在嘗試使用sql server架構在頁面中進行日誌記錄以及使用3層體系結構在asp.net中註冊頁面。我能夠從sql server數據庫中獲取數據，這是我在數據庫中創建表的時候手動插入的，我可以在我的登錄頁面中使用它。在註冊中獲取錯誤通過webform在SQL服務器數據庫表中插入值TEXTBOX
我也創建了一個註冊頁面，但我無法從註冊webform文本框到sqlserver數據庫中獲取值我收到一些錯誤，請親切地幫助我解決這個問題。
我給的SQL Server連接字符串在web.config中
我的SQL Server表創建代碼
CREATE TABLE LOGINDETAILS
(USERID VARCHAR(50),
PASSWORD VARCHAR (50)
);
INSERT INTO LOGINDETAILS (USERID,PASSWORD) values('sam', 'pass');
web.config中的連接字符串代碼
<?xml version="1.0"?>

}
protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(conString);
con.Open();
string ins= "Insert into [LOGINDETAILS](USERID, PASSWORD) VALUES ('" +TextBox1.Text+ "' , '" +TextBox2.Text+ "')";
SqlCommand com = new SqlCommand(ins,con);
DataSet du = new DataSet();
SqlDataAdapter sdi = new SqlDataAdapter(com);
sdi.Fill(du);
con.Close();
}
}
}
我得到的錯誤在這最後的代碼只是註冊按鈕，它是不能夠插入值的註冊網絡表單文本框到SQL Server數據庫表，也沒有反映出我想在sql server TABLE中添加的真實值，使用註冊webform並且還保存它。它發送一些錯誤值。請好心幫助我。

請幫助解決這個問題，
而不是說插入logindetails，textbox1。在循環前獲取變量中的textbox1數據，然後使用變量將其添加到logindetails中 – Tomm
您已經採取了有用的格式和很好的問題技巧，例如添加代碼，大小寫，粗體等，並且已經過時了。 –
請你詳細說明一下我沒有清楚地理解你？ Tomm – saurabh255
