Connection problem with C# and MySQL DB

Hi Everyone,

I work these days on how to connect my MySQL database with C # in Unity 3D. I found a document in a topic posted on the Unity forum as a tutorial for connecting to the database, I have suffered the steps perfectly but when the I build the code program gives me an error, it is here below:

Code (csharp):

1. The type 'System.ComponentModel.Component' is Defined in Year That Is not referenced assembly. You must add a reference to assembly 'System, Version = 2.0.5.0, Culture = neutral, PublicKeyToken = 7cec85d7bea7798e'.

It seems that the problem is caused by the object instance "MySqlCommand" but I can not correct the error knowing I am a C# amateur.

You Find here the tutorial in the doc attachment and sorry for my english
