MySqlException issue

Hi,

I'm learning to connect on my database.
This is my code :

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using MySql.Data.MySqlClient;
4.  
5. public class Connexion : MonoBehaviour
6.     {
7.  
8.     #region Propriétés Publiques
9.     public string account;
10.     public string password;
11.     public GameObject accountInputGO;
12.     public GameObject passwordInputGO;
13.     #endregion
14.  
15.     #region Propriétés Privées
16.     private string connexionString;
17.     private MySqlConnection connexionBDD;
18.     private MySqlCommand commandeSQL;
19.     private MySqlDataReader lecteurBDD;
20.     private bool erreurBDD;
21.     private string erreurBDDTexte;
22.     #endregion
23.  
24.     #region Méthodes Unity
25.     void Awake()
26.     {
27.         connexionString = "Server=localhost;Database=****;Uid=****;Pwd=*****";
28.         connexionBDD = new MySqlConnection(connexionString);    
29.     }
30.  
31.     void Update()
32.     {
33.          
34.     }
35.     #endregion
36.  
37.     #region Méthodes Autres
38.     public void CreationBoutton() {
39.         if (accountInputGO.GetComponent<UIInput>().value != "" && passwordInputGO.GetComponent<UIInput>().value != "") {
40.             account = accountInputGO.GetComponent<UIInput>().value;
41.             password = passwordInputGO.GetComponent<UIInput>().value;
42.             CreationCompte();
43.         }
44.    
45.     }
46.  
47.    public void CreationCompte() {
48.        try {
49.        }
50.  
51.        catch (MySqlException ex) {
52.  
53.        }
54.    }
55.  
56.     public void VoirCompteBoutton() {
57.     }
58.     #endregion
59. } // Fin du Script

catch (MySqlException ex) make this error :
The type caught or thrown must be derived from System.Exception


When i try this with classic C# application (without unity), there is no problem
When i try with unity, i have this error.

MySql.Data.dll (v2.0) is referenced in Unity and Visual studio
Could you help me before i become crazy ^^'

 

You say that this works in a "classic" C# application, but I assume you're not compiling exactly the same code, because I don't think a standalone C# app would like the "using UnityEngine" statement at the top of this file. Maybe there's some other minor difference you're overlooking between the working and non-working versions?

Have you tried just copying the entire sourcefile from the working "classic" C# app into Unity, with no modifications at all?

 

I have the same problem maybe someone found a solution for this?
