Take a look at the Histogram class in the source.

If it could help you, the way I defined "ranges" when "dims" parameter is 1:

float[] range_aux = {0, 256}; //define your own array
IntPtr[] ranges = new IntPtr[1]; //dims==1
ranges[0] = System.Runtime.InteropServices.Marshal.AllocHGlobal(2*sizeof(float));
System.Runtime.InteropServices.Marshal.Copy(range_aux, 0, ranges[0], 2);
.
.
.
.
System.Runtime.InteropServices.Marshal.FreeHGlobal(ranges[0]);
