Question

以下是我项目中登录表单上的按钮登录代码。作为表单的一部分，将创建一个包含数据库登录详细信息的txt文件。如果我只是从visual studio运行，项目运行正常，但是在我用VS创建一个exe后，我得到错误，说无法访问connection.txt。谢谢。

private void btnlogin_Click(object sender, EventArgs e)
{
    try
    {   
        // if the file doesn't exist.
        string fromConnFile = File.ReadAllText("connection.txt");
        NetworkConn ncBefore = JsonConvert.DeserializeObject<NetworkConn>(fromConnFile);
        String serverName = Base64.base64decode(ncBefore.servername);
        String userName = Base64.base64decode(ncBefore.username);
        String passWord = Base64.base64decode(ncBefore.password);
        String dataBase = Base64.base64decode(ncBefore.database);
        NetworkConn ncAfter = new NetworkConn()
        {   
            servername = serverName,
            username = userName,
            password = passWord,
            database = dataBase
        };
        String user = txtusername.Text.TrimStart().TrimEnd();
        String pass = txtpassword.Text.TrimStart().TrimEnd();
        // object for connecting database.
        MysqlQuery dataQuery = new MysqlQuery(serverName, userName, passWord, dataBase);
        DataTable userInfo = new DataTable();
        int ifSucceed = dataQuery.Login(user.Replace("'", ""), pass.Replace("'", ""), userInfo);

        if (ifSucceed == 1)
        {
            if (userInfo.Rows.Count == 1)
            {
                if (userInfo.Rows[0][0].ToString() == "admin")
                {
                    this.Hide();
                    Admin newform = new Admin(dataQuery, userInfo);
                    newform.Closed += (s, args) => this.Close();
                    newform.Show();
                }
            }
            else if (userInfo.Rows.Count > 1)
            {
                Console.WriteLine("There are more than 1 rows in the table");
            }
            else
            {
                Console.WriteLine("Please check");
            }
        }
    }
    catch (FileNotFoundException fnfe)
    {
        MessageBox.Show("Please set the network");
    }
