如何在没有任何网络调用的情况下WCF iis托管的应用程序运行？

Question

I wrote some WCF application that expose restful service.

This application bring the information from file and on any restful call its return some data from this file.

I trying to make my application to read the file before any first restful call but i can't find any way to do it.

The only thing that i found is to popup the reading file method on the first time that any restful method will call - and by define the WCF interface as

   [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.Single)]

I don't need to read again and again from the file - and i can use one reading and keep the data on the memory.

But the first reading .. this can't be done in the restful method call

Any help please ..

Thanks.

Using global.asax

The global.asax file is also known as the ASP.NET “HTTP” application file. It is an optional file and if there is one, it needs to be in the root of an ASP.NET application. It contains code to handle application-level events raised by ASP.NET or HttpModules. It is tightly coupled with the ASP.NET HTTP pipeline.

You will want to utilize the Application_Start method.
