It is a local file. Why do you think there may be issues for network based file? For example scenario?

The reason why I keep it open is, the content writes to the file depends on ad-hoc client request, if no request, no write operation, if many requests, I need write a lot of stuff. It is impossible to predict the # of request of clients.

 using (System.IO.StreamWriter sr = new System.IO.StreamWriter("filename", true))
 {
    sr.WriteLine("test message");
     sr.Flush();
}

My question is, if I obtain the handle of the StreamWriter too long without any write operations (for example, 2 days or longer), will the handle (or the underlying file) be closed by some parties (e.g. CLR, OS, etc.) -- like timeout of socket?

whether file will be automatically closed if open too long without any operation?

I assume that each of these compilers has its own JIT functionality. Is this correct?

I have read that the C++ compiler supports function inlining but the C# compiler does not

Member 3919049 wrote:

Has MS updated the C# compiler to support function inlining or does function inlining still not exist in the C# compiler?

Member 3919049 wrote:

Is there any reason why the C# compiler does not do function inlining?

Member 3919049 wrote:

It seems like function inlining would provide a big performance improvement

Member 3919049 wrote:

it seems like MS has already done the work to define this logic for the C++ compiler

Member 3919049 wrote:

so it doesn't seem like it would be too complicated to implement similar logic in the C# compiler....
