我創建一個簡單的註冊頁面我得到我相信有不能夠找到我所創建的表做一個錯誤,但我在當地做到了。asp.net註冊頁面不能正常工作
這裏是我的錯誤:
類型的「System.Data.SqlClient.SqlException」發生在 System.Data.dll中,但在用戶代碼
其他沒有處理的異常信息:關鍵字「表格」附近的語法不正確。
任何幫助將是非常美妙的。
下面我發佈,我有羽絨到目前爲止代碼:

{
SqlConnection conn =
new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
conn.Open();
string checkuser = userchecker();
SqlCommand com = new SqlCommand(checkuser, conn);
int temp = changehere(com);
conn.Close();
if (temp == 1)
{
Response.Write("User Already Exists");
}
}
}

private static int changehere(SqlCommand com)

你的表名是什麼? – SilentCoder
dbo.Table是我的表名 – bootle
當你得到這個例外?在userchecker()? – Forlani
