我想写一个本地程序的管理和安装系统，我的家庭网络，我想我得确定下来的技术：

I am trying to write a local program management and install system for my home network, and i think i've got the technologies nailed down:

在C＃/。NET / WPF客户端 Lua的安装脚本支持（通过LuaInterface） 在SQL Server的防爆preSS维护程序的数据库

但是我不能确定具体是什么我会使用C＃连接到数据库。是不是有什么内置在.NET框架呢？奖励积分，如果你对我应该用什么与该数据库交互的建议。

However i'm unsure what specifically i'll use to connect C# to the database. Is there something built into the .NET framework for this? Bonus points if you have a suggestion on what i should use for interacting with said database.

我敢肯定有很多更在那里 - 只是谷歌ADO.NET和教程......

I'm sure there's plenty more out there - just google for "ADO.NET" and "Tutorial" ......

更新：

如果你想连接到您的本地SQL Server防爆preSS，并连接到罗斯文数据库，并从客户表中读出前5名客户，你必须做这样的事情

If you want to connect to your local SQL Server Express, and connect to the "Northwind" database, and read the top 5 customers from the "Customers" table, you'd have to do something like this:

string connectionString = "server=(local)SQLExpress;database=Northwind;integrated Security=SSPI;";

using(SqlConnection _con = new SqlConnection(connectionString))
{
   string queryStatement = "SELECT TOP 5 * FROM dbo.Customers ORDER BY CustomerID";

   using(SqlCommand _cmd = new SqlCommand(queryStatement, _con))
   {
      DataTable customerTable = new DataTable("Top5Customers");

      SqlDataAdapter _dap = new SqlDataAdapter(_cmd);

      _con.Open();
      _dap.Fill(customerTable);
      _con.Close();

   }
}

现在你将有所有5个顶级客户从数据表中的Northwind数据库，您可以检查它们，把它们打印出来，操控起来 - 任何你想做的事情

Now you would have all 5 top customers from your Northwind database in the DataTable and you can inspect them, print them out, manipulate them - whatever you want to do.

这是ADO.NET在行动！

That's ADO.NET in action!

作为连接字符串的细节 - 什么样的选择，你可以使用，它应该是什么样子，请查看连接字符串网站 - 它拥有吨的例子和说明

As for the details of the connection string - what options you can use and what it should look like, check out the Connection Strings web site - it has tons of examples and explanations.
