double __gc * cast to double*

All:

Can double __gc * be cast to a double*? In C# the fixed(double* pX = x) can
be used. Is there an equivalent in C++.NET?

Thanks in advance.

You should be able to use a pinning pointer to acheive the same result as
the cast, no?

// Double on the managed heap

System::Double __gc *pd1 = new System::Double(3.0);

// Get a pointer to a double which does not get moved/collected while in
scope

double __pin *pd2;

// Same net effect as cast?

pd2 = pd1;

Will
