Memory usage of DotNET app

Question

My application (DotNET) runs as a plug-in inside a C++ standalone app that exposes a C++/CLI SDK.

It is very easy for my users to generate large amounts of data and I'd like to offer an abort option if the memory consumption of my plug-in + the base application reaches -say- 90% of the legal maximum.

How can I measure the total memory consumption (ideally for both the managed and unmanaged code) and how do I know how much memory windows allows for the current application?

The Process class provides most of this information. I think what you're after would be Process.PrivateMemorySize64.

You should be able to do:

var memoryUsage = Process.GetCurrentProcess().PrivateMemorySize64;

Yes! That's it! I was already worried I had to go through PInvoke to get to this. – David Rutten Sep 04 '09 at 00:10

The Process class has many nice metrics like this - take a look at the docs, and you'll see many of them. – Reed Copsey Sep 04 '09 at 00:11

I recommend a profiling tool: dotTrace works really well.

What I need is a way for my application to know how much memory it's using at runtime. I'm not looking for a profiling app. Essentially, what I want is the number of Private Bytes used by my process as visible in the Process Explorer / Task Manager. – David Rutten Sep 03 '09 at 23:48

GetProcessMemoryInfo and check the PrivateUsage in the PROCESS_MEMORY_COUNTERS_EX.

Update

Obviously I misred the question and though you want the value from the CLI SDK side of the app. In the managed side, you already got the correct answer.
