在C＃中将double []转换为double *

Question

How to convert double[] to double* in c#

I was trying

unsafe {
 System.Double[] a = { 1.0, 2.0, 3.0, 4.0, 5.0 };
 fixed(double *aP = a)
   for (int i = 0; i < a.Length ; i++)
   {
    //need to copy?
   }
}

This plays nice in my (very limited, ran it once) testing.

  unsafe { 
    Double[] a = { 1.0, 2.0, 3.0, 4.0, 5.0 };
    fixed (double* aP = a) {
      for (int i = 0; i < a.Length; i++) {
        System.Console.WriteLine(*aP + i);
      }
    }
  }
