I've created an application (using c# winforms) in which I'm managing item sheets such books, music and movie dvds, games, etc. Those sheets contain basic information such title, synopsis, author, etc. There are even images (full-size + thumbnail).

So now I'm entering the stage of development where I need to save all the changes and load them again when I re-open the application. It's the first time I'm doing this kind of operation so I'm unsure of the best ways to do this.

So how do we save/load a database in a C# winform application? Are there best or faster methods than others?

Any link to tutorials would be greatly appreciated, I haven't found any valuable ones on my own, or the ones I've found dealt with Web applications.

Thank you!

Microsoft Entity Framework is the way to go.

I'd suggest to pay close attention to CodeFirst feature of EF because you have an application but don't have a DB yet. Here is Tutorial: Code First with EF 4.1

您可以在 Windows 窗体应用程序中使用“SQL 精简版”（我称之为本地 SQL）。因此，您无需连接到其他 DBMS 即可轻松加载/保存数据库。 http://www.microsoft.com/sql/editions/compact/default.mspx

将数据库数据加载到 Winforms 应用程序中

如果您不希望使用实体框架（例如在性能关键的情况下），则直接使用 ADO.Net和System.Data.SqlClient 是另一种方法。此方法假定您使用的是Microsoft SQL Server：

该方法可以这样调用：GetSqlData("Select * from myTable").

public static DataTable GetSqlData(string sql)
{
    // get Connectionstring from app.config 
    string connStr = System.Configuration.ConfigurationManager.AppSettings["YourConnection"];
    using (SqlConnection myConnection = new SqlConnection(connStr))
    {
        myConnection.Open();
        DataTable dt = new DataTable();
        using (var command = new SqlCommand())
        {
            command.Connection = myConnection;
            command.CommandText = sql;
            SqlDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection);                                        
            dt.Load(reader);
        }
        return dt;
    }            
}// End of GetSqlData

关于教程

由于来自微软的名为 windowsclient.net 的伟大网站（包含大量用户输入和官方视频）已经消失（1、2 ），您可以通过谷歌搜索beth massi forms over data 视频系列或只是form over data，您会发现剩下的来自 windowsclient.net 网站。
