连续处理参数不再是 supported.NPGSQL

Question

我刚刚将我的 npgsql 从 2.5.5 升级到 3.1.1，我收到了这个运行时错误。

我的 DbConnection class

 public static string ServerConnectionString()
    {
        var connectionStringBuilder = new NpgsqlConnectionStringBuilder
        {
            Host = ConfigurationManager.AppSettings["Server"],
            Username = ConfigurationManager.AppSettings["UserId"],
            Database = "postgres",
            Password = ConfigurationManager.AppSettings["Password"],
            CommandTimeout = Convert.ToInt32(ConfigurationManager.AppSettings["CommandTimeout"]),
            ApplicationName = EverestEnums.ConnectionApplicationName.EverestServerChecker.ToString(),
            //  MaxPoolSize = 200,
            //   SyncNotification = true,
            KeepAlive = 1,
            ConnectionLifeTime = 1,
          //  MinPoolSize = 1,
            Pooling = false
        };
        return connectionStringBuilder.ConnectionString;
    }

堆栈跟踪

因为它工作正常 before.But 连接有一些问题 pooling.And 然后我升级了 npgsql 和这个 rumtime error.Any 帮助。

当您在 NpgsqlConnectionStringBuilder 上获取或设置 ConnectionLifeTime 属性时，似乎抛出了异常。属性已过时，现在由连接空闲生命周期属性取代（请参阅 http://www.npgsql.org/doc/migration.html）。尝试改用它：

 public static string ServerConnectionString()
    {
        var connectionStringBuilder = new NpgsqlConnectionStringBuilder
        {
            Host = ConfigurationManager.AppSettings["Server"],
            Username = ConfigurationManager.AppSettings["UserId"],
            Database = "postgres",
            Password = ConfigurationManager.AppSettings["Password"],
            CommandTimeout = Convert.ToInt32(ConfigurationManager.AppSettings["CommandTimeout"]),
            ApplicationName = EverestEnums.ConnectionApplicationName.EverestServerChecker.ToString(),
            //  MaxPoolSize = 200,
            //   SyncNotification = true,
            KeepAlive = 1,
            ConnectionIdleLifetime = 1,
          //  MinPoolSize = 1,
            Pooling = false
        };
        return connectionStringBuilder.ConnectionString;
    }
