使用 C# .NET Core 2.1 查询 DynamoDB GSI 时出错

Question

我收到以下代码的以下错误：

错误 CS1061“AsyncSearch”不包含“GetAwaiter”的定义，并且找不到接受“AsyncSearch”类型的第一个参数的可访问扩展方法“GetAwaiter”（您是否缺少 using 指令还是程序集参考？

DynamoDBContext context = new DynamoDBContext(client);

                DynamoDBOperationConfig indexHashRangeOpConfig = new DynamoDBOperationConfig()
                {
                    IndexName = "ProjectFGDIndex",
                    ConsistentRead = false,
                };

                IEnumerable<Dashboardreq> list = await
                context.QueryAsync<Dashboardreq>(req.ProjectName, QueryOperator.Between, new string[] {
                                                 req.FileGeneratedFromDate+" " + Constants.DayBeginTime,
                                                 req.FileGeneratedToDate+" " + Constants.DayEndTime
                                                 });

错误发生在 await context.QueryAsync 调用中。 寻求指导...

我解决了这个问题，对代码进行了以下更改：

List<Dashboardreq> list =
                await context.QueryAsync<Dashboardreq>(req.ProjectName, QueryOperator.Between, new string[] {
                                                 req.FileGeneratedFromDate+" " + Constants.DayBeginTime,
                                                 req.FileGeneratedToDate+" " + Constants.DayEndTime
                                                 }, indexHashRangeOpConfig).GetRemainingAsync();
