在sqlconnection中出错 [英] got a error in sqlconnection

问题描述

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;

public partial class testing : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
          sqlconnection con=new sqlcoonection()


    }

i已正确完成所有操作，但是我在sqlconnection中得到红色下划线，同时在button1_click

i have done everything correctly but i got red underline in sqlconnection while defining under button1_click

推荐答案

下定义C＃是区分大小写的，并且确实喜欢正确的拼写，尝试更改：

C# is case sensitive and does like correct spelling as well, try changing:

sqlconnection con=new sqlcoonection()

要

To

SqlConnection con=new SqlConnection();

（不要忘记行尾的分号）

(Don''t forget the semicolon at the end of the line, either)

了解如何使用IDE！

设置光标进入sqlconnection，并在键盘上键入ctrl + space。瞧，这个词已经改变了一点 - 你看到了区别吗？

Learn how to use your IDE!
Set the cursor into "sqlconnection", and on your keyboard type ctrl+space. And voilà, the word has changed a little - do you see the difference?

试试这个。



SqlConnection sqlConnectionString = new SqlConnection（Data Source = servername; Initial Catalog = dbName; Integrated Security = True）;

try this.

SqlConnection sqlConnectionString = new SqlConnection("Data Source=servername;Initial Catalog=dbName;Integrated Security=True");
