C# Quartz.NET在执行过程中跳过步骤
我需要你在QUARTZ.NET上的宝贵建议。我使用此计划在每10秒后运行我的函数。实际上,我的代码是从json文件中获取数据,并将其与数据库SQL server进行比较。如果id与数据库匹配,那么它将不做任何事情,否则它将推送产品。某段时间代码运行成功,我没有得到重复的条目。但有时它会在数据库中插入重复的值,并且只能跳过exist=(int)cmd.ExecuteScalar();请告诉我该怎么办。因为我不能将调度时间从10秒增加到10秒以上。以及如何避免遗漏其中的一行。下面是我的代码。这将对我大有帮助。。请帮忙。谢谢C# Quartz.NET在执行过程中跳过步骤,c#,quartz-scheduler,quartz.net,C#,Quartz Scheduler,Quartz.net,我需要你在QUARTZ.NET上的宝贵建议。我使用此计划在每10秒后运行我的函数。实际上,我的代码是从json文件中获取数据,并将其与数据库SQL server进行比较。如果id与数据库匹配,那么它将不做任何事情,否则它将推送产品。某段时间代码运行成功,我没有得到重复的条目。但有时它会在数据库中插入重复的值,并且只能跳过exist=(int)cmd.ExecuteScalar();请告诉我该怎么办。因为我不能将调度时间从10秒增加到10秒以上。以及如何避免遗漏其中的一行。下面是我的代码。这将对我
