using System;
using System.Data;
using System.Data.Common;
using System.Data.sqlite;

namespace test
{
  class Program
  {
    static void Main(string[] args)
    {
      sqliteConnection.CreateFile("/Users/smcho/Desktop/sqlite-1/example/mydatabasefile.db3");
    }
  }
}

我运行了以下命令

mcs db.cs -r:System.Data.dll -r:System.Data.sqlite.dll

但是,我收到如下错误消息.

** (/opt/local/lib/mono/1.0/mcs.exe:43249): WARNING **: The class System.Data.Common.DbConnection could not be loaded,used in System.Data,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089
db.cs(12,7): error CS0103: The name `sqliteConnection' does not exist in the current context
Compilation Failed: 1 error(s),0 warnings

可能有什么问题？
