Question

我在SQLite中有一个小项目。我在ListView中显示了所有这些示例：

SQLiteConnection oSQLiteConnection =
                new SQLiteConnection("Data Source=database.s3db");
            SQLiteCommand oCommand = oSQLiteConnection.CreateCommand();
            oCommand.CommandText = "SELECT * FROM PERSONS";
            m_oDataAdapter = new SQLiteDataAdapter(oCommand.CommandText,
                oSQLiteConnection);
            SQLiteCommandBuilder oCommandBuilder =
                new SQLiteCommandBuilder(m_oDataAdapter);
            m_oDataSet = new DataSet();
            m_oDataAdapter.Fill(m_oDataSet);
            m_oDataTable = m_oDataSet.Tables[0];
            lstItems.DataContext = m_oDataTable.DefaultView;

我还有一个按钮，打开新表单，其中包含名称，用户名等字段，我想点击保存（在新的打开表单中）并将新行保存到我的数据库并更新此视图。我怎样才能做到这一点？在我的＆＃34; min＆＃34; viewI可以像这样做ststaic

DataRow oDataRow = m_oDataTable.NewRow();
oDataRow[1] = "Name";
oDataRow[2] = "Username";
m_oDataTable.Rows.Add(oDataRow);
m_oDataAdapter.Update(m_oDataSet);

如何从新表单中保存？我不能这样做：（

我喜欢使用实体框架

 using (var context = new Db())
        {
            try
            {
               ...
                context.SaveChanges();
            }
            catch (Exception e)
            {

            }
        }

C＃从新表单保存到SQLite
