Any know how to convert a managed array to an unmanaged array (ptr)?

// Managed
float[] f = new float [6];

// Unmanaged
unsafe
{
float *pArray = f; // No good

float *pArray = (float*) f; // Compiler still doesn't allow it
}

I'm assuming there might be some marshalling involved.

Also, are unsafe {} blocks the only way to combined managed and unmanaged
logic?

Sorry... I'm still pretty new to mixing managed and unmanaged code.
 
The first declaration you have is not of a managed array. Neither in VC
2002/2003 syntax, nor in VC 2005 syntax. And an unsafe" block is not C++,
but C#.

Are you sure you are posting in the right newsgroup?

Thanks.

Sorry... It is a C# question.
