C#调用SQLite示范代码

C#调用SQLite演示代码

&nbsp&nbsp&nbsp1.首先得去网上下载一个叫System.Data.SQLite.dll的文件

&nbsp&nbsp&nbsp2.跟添加其他dll一样,先Add&nbspReference添加此dll

&nbsp&nbsp&nbsp3.添加命名空间using&nbspSystem.Data.SQLite

&nbsp&nbsp&nbsp4.接下来就是写代码了

   string connecString = @"Data Source=D:\SQLite.db;Pooling=true;FailIfMissing=false";       /*D:\sqlite.db就是sqlite数据库所在的目录,它的名字你可以随便改的*/
   SQLiteConnection conn = new SQLiteConnection(connectString); //新建一个连接
   conn.Open();  //打开连接
  
      SQLiteCommand cmd = conn.CreateCommand();
      cmd.CommandText = "select * from orders";   //数据库中要事先有个orders表
      cmd.CommandType = CommandType.Text;
       using (SQLiteDataReader reader = cmd.ExecuteReader())
          {
                while (reader.Read())
                    Console.WriteLine( reader[0].ToString());
            }
 

&nbsp&nbsp&nbsp用法其实跟平时用C#操作一般的数据库差不多.

&nbsp&nbsp另外如果要用到Linq的话得用到另外一个dll文件,System.Data.SQLite.Linq.dll
