C# 脚本：我需要添加一个时间延迟

基本上，这个脚本会被告知每10分钟运行一次，但我只希望脚本在伦敦时间晚上9点到凌晨4点运行，有人能帮忙吗

另外，我想限制脚本每小时发送的电子邮件不超过500封

                  /*Email Client configuration. Here you will need to specify Server, user name and password for your SMTP server, and also testing tag*/
             string SMTPServer = "mail.justshipit.net";
             int SMTPPort = 26;
             string UserName = "no-reply+justshipit.net";
             string Password = "00000";
             string FromEmail = "no-reply@justshipit.net";
             string FromName = "Zoozio @ Amazon";

//email subject and email body
             string Subject = "Please Leave feedback for your [{Source}] order from SUPER COOL STORE";
             string eBayEmailBody = "Hello, [{Name}].\r\n\r\nYou recently purchased:\r\n\r\n[{ItemList}]\r\n\r\nWe hope everything was satisfactory and would really appriciate it if you could go to www.amazon.co.uk/feedback and leave us some positive feedback\r\nif you had any issues please get in contact with us ASAP as we want to sort things out.\r\n\r\nCall Us:0843 289 2766\r\n\r\nMany Thanks\r\nAdam\r\nCustomer Care Manager ";


             /*query syntax. Here we will select all orders processed 14 days ago but not older than 1 month, that don't have FEEDBACK email sent
              and order item table. Two queries in one request
             */
             string query =@"SELECT pkOrderId,cEmailAddress, cFullName, [Source]
FROM [Order] o
LEFT OUTER JOIN Order_LifeHistory ls on ls.fkOrderId = o.pkOrderID and ls.fkOrderHistoryTypeId='EMAIL_SENT'    and ls.Tag='FEEDBACK'
WHERE 
    o.bProcessed = 1 AND o.HoldOrCancel=0 AND o.dProcessedOn > DATEADD(D,-10,GETDATE()) AND ls.sid_history is null 
    AND o.Source IN ('AMAZON');
    SELECT pkOrderId,ItemNumber = oi.ItemNumber,ItemTitle = sis.cItemName
    FROM [Order] o
    INNER JOIN [OrderItem] oi on oi.fkOrderID = o.pkOrderID
    INNER JOIN [StockItems] sis on sis.pkStockID = oi.fkStockID
    LEFT OUTER JOIN Order_LifeHistory ls on ls.fkOrderId = o.pkOrderID and     ls.fkOrderHistoryTypeId='EMAIL_SENT'    and ls.Tag='FEEDBACK'
WHERE 
    o.bProcessed = 1 AND o.HoldOrCancel=0 AND o.dProcessedOn > DATEADD(D,-10,GETDATE()) AND ls.sid_history is null 
    AND o.Source IN ('AMAZON');"; 
//SELECT pkOrderId,ItemNumber = oi.ItemNumber,ItemTitle = sis.cItemName
//FROM [Order] o
//INNER JOIN [OrderItem] oi on oi.fkOrderID = o.pkOrderID
//INNER JOIN [StockItems] sis on sis.pkStockID = oi.fkStockID

我建议制定一个计划框架

Quartz.net

是一个很好的工具，并且非常容易学习/实现

您可以始终使用计划任务/cron作业来实现计时器。

为此使用内置的。不需要建立一个定制的应用程序，只是为了安排脚本的运行。我建议将来当你发布问题时，你考虑发布不暴露你的企业/客户的内部模式、基础设施和身份的代码：
