如何在Visual Studio中使用C#代码打开和关闭与服务器资源管理器中的数据库（.db）数据连接的连接？

下面的代码是正在编写的应用程序的数据访问层。该代码有两种方法，使用

OdbcConnection

和

OdbcDataAdapter

尝试两次连接到.db数据库文件，该文件在本地文件路径中设置并引入Visual Studio Server Explorer数据连接：

using System.Data;
using System.Data.Common;
using System.Data.Odbc;
using System.Windows.Forms;

namespace Data.DataAccess
{
    public class PatientDatabase
    {
        public OdbcDataAdapter ConnectAndCreateDataAdapter()
        {
            string selectCommand = "select * from patient";

            var connectionString = "Driver={SQL Anywhere 10};DBN=Training1;UID=dba;PWD=sql;Data Source=C:\\Projects\\Training\\Training1.4.2\\Training1.db;";

            OdbcConnection connection = new OdbcConnection(connectionString);
            connection.Open();

            var dataAdapter = new OdbcDataAdapter(selectCommand, connectionString);

            return dataAdapter;
        }

        public void ConnectAndPopulateDataGridView(DataGridView dataGridView)
        {
            BindingSource patientBindingSourceTest = new BindingSource();
            dataGridView.DataSource = patientBindingSourceTest;

            string selectCommand = "SELECT patient.first_name + ' ' + patient.last_name as patient_name, patient.patient_id, patient.address, patient.city, patient.state, patient.zipcode, patient.phone, patient.notes, patient.classification_id, patient_classification.description from patient, patient_classification right join patient on patient.classification_id = patient_classification.patient_classification_id";

            var connectionString = "Driver={SQL Anywhere 10};DBN=Training1;UID=dba;PWD=sql;Data Source=C:\\Projects\\Training\\Training1.4.2\\Training1.db;";

            OdbcConnection connection = new OdbcConnection(connectionString);
            connection.Open();

            var dataSet = new DataSet();

            var dataAdapter = new OdbcDataAdapter(selectCommand, connectionString);

            DataTableMapping patientTableMapping = new DataTableMapping("Table", "patient");
            dataAdapter.TableMappings.Add(patientTableMapping);
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("patient_id", "Patient ID"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("patient_name", "Patient Name"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("address", "Address"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("city", "City"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("state", "State"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("zipcode", "Zip Code"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("phone", "Phone"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("notes", "Notes"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("classification_id", "Classification ID"));
            patientTableMapping.ColumnMappings.Add(new DataColumnMapping("description", "Classification"));

            dataAdapter.Fill(dataSet);

            patientBindingSourceTest.DataSource = dataSet.Tables["patient"].DefaultView;

            dataGridView.Columns["Notes"].Visible = false;
            dataGridView.Columns["Patient ID"].Visible = false;
            dataGridView.Columns["Classification ID"].Visible = false;

            var commandBuilder = new OdbcCommandBuilder(dataAdapter);

            dataGridView.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
        }
    }
}

现在的问题是，这段代码工作和功能都非常好。。。但是

打开解决方案时，数据连接（数据库）开始关闭。上面的图片链接显示了我所指的内容

问题是，除非连接“打开”，否则我的代码无法工作

connection.Open（）不会打开该连接，即使它们在创建时具有相同的连接字符串。打开连接包括手动右键单击数据连接中列出的数据库，然后单击“刷新”

所以

是否有任何方法可以通过代码完成此右键单击？我可以像打开连接时那样打开连接吗。。。SQL Server？否则，当我编译并发布代码时会发生什么？数据库是否在应用程序中构建并响应代码
connection.Open（）或当数据适配器打开连接时？
只需将数据库文件放入启动项目文件夹的bin\debug中，并将连接路径更改为“DBF=Training1.db；UID=dba；PWD=sql”，我的坏消息。很抱歉，在我解决问题后，花了这么长时间才发布答案。
