使用c#访问microsoft sql server compact （初级）

sql server compact是微软推出的免费嵌入式数据库，可以通过sql server 2005管理器，来连接管理它。

下面是一段简单的访问示例。

using System;

using System.Collections.Generic;

using System.Text;

using System.Data.SqlServerCe;

using System.IO;

using System.Data;

namespace ConsoleApplication8

{

class Program

{

static void Main(string[] args)

{

string ceDataFilePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "firstSqlServerCe.sdf");

const string CONN_STRING = "Data Source=firstSqlServerCe.sdf;encryption mode=platform default;Password=2654;";

if (!File.Exists(ceDataFilePath))

{

using (SqlCeEngine engine =

new SqlCeEngine(CONN_STRING))

{

engine.CreateDatabase();

}

using (SqlCeConnection conn = new SqlCeConnection(CONN_STRING))

{

conn.Open();

using (SqlCeCommand comm = new SqlCeCommand("create table test(col1 INT,col2 NVARCHAR(100))", conn))

{

comm.ExecuteNonQuery();

}

using (SqlCeCommand comm = new SqlCeCommand("insert into test values(1,'hello 1')",conn))

{

comm.ExecuteNonQuery();

}

}

}

using (SqlCeConnection conn = new SqlCeConnection(CONN_STRING))

{

using (SqlCeCommand comm = new SqlCeCommand("select * from test",conn))

{

conn.Open();

using (IDataReader rdr = comm.ExecuteReader())

{

while (rdr.Read())

{

Console.WriteLine("{0}\t{1}",rdr["col1"],rdr["col2"]);

}

}

}

}

Console.Read();

}

}

}
