Which assembly code do you want to run have in your code x86 or MSIL
If the answer is x86 you are out of luck... one of the few ways you could do that would be to build the ASM code into another project just as an unmanaged C++ dll and call it from your C# app.
If MSIL... you can... just not directly, nor is it recommended or supported. To do so, take a look at the following links where a couple of people have built some small tools for inline MSIL.
I don't believe you can, directly. The .NET framework is designed to compile to MSIL, so there's a layer between your code and the machine, which makes assembly there unlikely. You can do it in C++ tho, and you can call a C++ dll from C# using COM or just plain interop.
Just a quick addition to the other comments. If you're talking about assembly language (x86 or otherwise), you can do it by implementing in C++/CLS (managed C++) and then calling the code from C#. One important thing to note is that your application will require Full Trust, as you'll be calling unmanaged code. (The same would be true if you were using a COM object or P/Invoking into an unmanaged DLL.)
The real question is what are you thinking of doing that would require assembly language It's amazing what can be accomplished with a combination of "unsafe" C#, managed C++, or P/Invoking unmanaged C/C++. Also just because it's managed doesn't mean it's slow. I would highly recommend reading the following before embarking on any assembly language or unmanaged C++ endeavours:
can i use assemblers code in c# code?

To call unmanaged (or C++)( code from managed code (or C#), this might help:
