C# 内存泄露如何发现问题出在哪 里？

问题遇到的现象和发生背景

。netframework 4.8 程序执行后 ，内存不断的增加，过了一夜后，从开始的54M到 1000M，这就是内存泄露吧？ 问题出在哪 里？
workID一直为NULL，我的队列是为空的，只是测试这段代码。

问题相关代码，请勿粘贴截图

            IsEnabledStopButton = true;

                    string workID = await _redisStorage.ReadAmsOrderAsync();
                    //string workID = null;
