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();
}
}
}
