Can you write a block of c++ code inside C#?

Is it possible to write C++ code inside of C# purely?

For example:

class MyClass
{
    public void MyCSharpFunction(){Console.WriteLine("Hello World!");}
    public void MyCPlusPlusFunction(){std::cout<<"Hello World"<<std::endl;}
}

I know that you can do this through DLL’s, however, I could not find any information about if it was possible to do this without the use of DLL’s.

You can use unsafe code, but not directly C++:

// cs_unsafe_keyword.cs
// compile with: /unsafe
using System;
class UnsafeTest 
{
   // unsafe method: takes pointer to int:
   unsafe static void SquarePtrParam (int* p) 
   {
      *p *= *p;
   }
   unsafe public static void Main() 
   {
      int i = 5;
      // unsafe method: uses address-of operator (&)
      SquarePtrParam (&i);
      Console.WriteLine (i);
   }
}
