Marshal.Copy Method (IntPtr, Single, Int32, Int32)
Copies data from an unmanaged memory pointer to a managed single-precision floating-point number array.
Assembly: mscorlib (in mscorlib.dll)
[SecurityCriticalAttribute] public static void Copy( IntPtr source, float destination, int startIndex, int length )
source, destination, startIndex, or length is null.
Unmanaged, C-style arrays do not contain bounds information, which prevents the startIndex and length parameters from being validated. Thus, the unmanaged data corresponding to the source parameter populates the managed array regardless of its usefulness. You must initialize the managed array with the appropriate size before calling this method.
requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
