我可以有一个以上的配置连接与MVC迷你分析器

Question

我想在我的MVC3应用程序中使用Dapper和EF 4的混合物。是否可能有多个分析连接，或者共享一个分析连接?

Answer 1

是的，您可以使用EF profile连接与Dapper，这是我最终使用的。

    private static DatabaseContext GetDatabaseContext()
    {
        using (MiniProfiler.Current.Step("Create Oracle EF Context"))
        {
            var pConn = ProfiledConnection;
            return pConn.CreateObjectContext<DatabaseContext>();
        }
    }
    private static EFProfiledDbConnection ProfiledConnection
    {
        get
        {
            using (MiniProfiler.Current.Step("Create Oracle Profiled Connection"))
            {
                var connectionString =
                    ConfigurationManager.ConnectionStrings["DatabaseContext"].ConnectionString;
                var ecsb = new EntityConnectionStringBuilder(connectionString);
                var oraConn = new OracleConnection(ecsb.ProviderConnectionString);
                var pConn = new EFProfiledDbConnection(oraConn, MiniProfiler.Current);
                return pConn;
            }
        }
    }

然后我这样使用它们

            using (var ctx = GetDatabaseContext())
            {
                var result = ctx.SOME_EF_ENTITY.FirstOrDefault(c => c.LOGINNAME == username && c.PASSWORD == password);

                return result;
            }

和

        const string sql = @"
                    SELECT ppro_status_code_id 
                    FROM   ppro_status_codes 
                    WHERE  table_name = 'CLIENT_FC_SHARED' 
                        AND status_code = :status_code";
        using (var cnn = ProfiledConnection)
        {
            cnn.Open();
            var data = cnn.Query<dynamic>(sql, new { status_code = code });
            var result = data.First();
            var codeID = result.PPRO_STATUS_CODE_ID;
            return codeID;
        }
