Is unsafe C# garbage collected

I was reading about memory leaks in managed code and wondered if it was possible to create this in C# unsafe code?

unsafe
{
    while(true) new int; 
}

I wasn't sure if this would be caught by the GC if this was running as unsafe code?

Thanks

IMO unsafe only permits to use pointer types and proform C++ style pointer opeartion on memory. But to tell garbage collector not touch my code use fixed statement.

C# supports direct memory manipulation via pointers within blocks of code marked unsafe and compiled with the /unsafe compiler option.

The fixed statement is used to tell the garbage collector to not touch that code that was rounded with fixed statement

   unsafe
    {
       fixed (int* a = &b)   // tells garbage collector not touch 
       {
         *a = 9;
       }    
    }

The unsafe keyword just allows you to use unsafe code (pointers).

It doesn't change the semantics of ordinary code at all.
