C# 使用windows服务进行Csvhelper写入
我正在使用csvhelper和windows服务，该服务不间断运行。我想创建一个新的csv日志文件，只放置一次头值，直到文件大小增长到1000 kb，然后创建另一个新文件，使文件大小增长过大。此时，csv文件在windows服务启动时创建一次，但每次写入时都会重复头文件值 我们是否在csv助手中有一些配置属性来标记文件大小？ 请看一下代码，并建议是否可以在.NET4.0中高效地完成此操作。 Windows服务代码C# 使用windows服务进行Csvhelper写入,c#,.net,C#,.net,我正在使用csvhelper和windows服务，该服务不间断运行。我想创建一个新的csv日志文件，只放置一次头值，直到文件大小增长到1000 kb，然后创建另一个新文件，使文件大小增长过大。此时，csv文件在windows服务启动时创建一次，但每次写入时都会重复头文件值 我们是否在csv助手中有一些配置属性来标记文件大小？ 请看一下代码，并建议是否可以在.NET4.0中高效地完成此操作。 Windows服务代码 public partial class Service1 : ServiceBa

我欢迎您的建议，请告诉我您是否可以找到更好的方法来解决此问题。您能否检查成为Windows服务的一部分是否对问题的发生很重要？听起来很奇怪，如果你需要滚动日志，你在简单的情况下看不到它（比如基本控制台应用），我认为最好切换到一些也支持登录到CSV的日志库（比如NLog）我想创建一个新的csv日志文件，只放置一次头值，直到文件大小增长到1000 kb，然后创建另一个新文件，即使我使用console app或wpf，它会有什么不同。问题是，我要创建一个日志文件，在创建文件时，头只放入一次。Col1header、Col1header、Col1header、Col1headerColheader1、Colheader2、Colheader3----------------------value1、value2、value3 value1、value2、value3文件大小达到1000kb时创建一个新文件。Colheader1，Colheader2，Colheader3--------------------值1，值2，值3值1，值2，值3
