如何将本地数据库连接到ADO.NET C＃？ [英] How to connect local DB to ADO.NET C#?

问题描述

您好。我用一些表创建了本地DB DBSimple.sdf。然后我发布了代码：

Hello. I created local DB DBSimple.sdf with some tables. Then i published code:

private string CommandText = "SELECT CustomerID, CompanyName, ContactName, ContactTitle, Address, City, Region, PostalCode, Country, Phone, Fax FROM Customers";

private string ConnectionString = "";
SqlDataAdapter dataAdapter = new SqlDataAdapter(CommandText, ConnectionString); 

对于本地文件DBSimple.sdf，ConnectionString必须是什么？ （它数据库显示在Data Connections / Server Eplorer）
