Well, after a lot of search and work, I have chose to change my connectionString like it:

@{
    Layout = "~/_Layout.cshtml";
    Page.Title = "Dossier Racine";
    var srv = Request.QueryString["server"];
    var usr = Request.QueryString["username"];
    var pwd = Request.QueryString["password"];  
    var db = Database.OpenConnectionString("server="+srv+";database=ReportServer;uid="+usr+";pwd="+pwd+"","System.Data.SqlClient");    
    var sqlFile = " SELECT *"
        + " FROM Catalog";
    var selectedData = db.Query(sqlFile);    
 }
