如何使用连接字符串&它显示无法识别的转义序列？

Question

stringConnectionString = "Data Source = 192.168.0.222; Initial Catalog= ;User ID=xxxxxxx;Password=yyyyyy";

这是我的连接字符串，我不知道如何分配连接字符串&这是我的文件位置

D:\Gurusoft\Gowtham\work\G9HCMS\G9Collaboration\DataProvider\clsPatients.cs

我的全部代码

公共部分类MainWindow :窗口{ public MainWindow() { InitializeComponent()；}

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        string stringConnectionString = null;           
        DataSet objDataSet;
        SqlCommand objSqlCommand;


        try
        {
            int intNum = 0;
            objDataSet = new DataSet();
            objSqlCommand = new SqlCommand();
            stringConnectionString = (@"Data Source = 192.xxx.0.yyy; Initial Catalog=C:User\G9HCMS\clsPatients.cs;Persist Security Info=true;User ID=xxxx;Password=yyyyy");
            SqlConnection objSqlConnection = new SqlConnection(stringConnectionString);

            {

                if (objSqlConnection != null)
                {
                    objSqlConnection.Open();
                    SqlDataAdapter objSqlDataAdapter = new SqlDataAdapter("select * from MR_Patients", objSqlConnection);
                    // objSqlCommand.Connection = objSqlConnection;                                                                
                    objSqlDataAdapter.Fill(objDataSet);

                    for (intNum = 0; intNum <= objDataSet.Tables[0].Rows.Count - 1; intNum++)
                    {
                        MessageBox.Show(objDataSet.Tables[0].Rows[1].ItemArray[1].ToString());

                    }
                }
                else
                {
                    objSqlConnection.Close();
                    MessageBox.Show("connection Error");

                }
            }
        }
        catch (Exception objException)
        {
            MessageBox.Show("Exception" + objException.ToString());


        }
    }
}

}

如何设置此连接字符串

Answer 1

尝试在连接字符串之前添加@

new SQlConnection(@"Data Source=HOGAR\SQLEXPRES;Init...");

或者使用\而不是\

new SQlConnection("Data Source=HOGAR\\SQLEXPRES;Init...");
