Marshal.Copy Method (Char, Int32, IntPtr, Int32)
Copies data from a one-dimensional, managed character array to an unmanaged memory pointer.
Assembly: mscorlib (in mscorlib.dll)
public static function Copy( source : char, startIndex : int, destination : IntPtr, length : int )
You can use this method to copy a subset of a one-dimensional .NET-based array to an unmanaged C-style array.
This method uses SecurityAction.LinkDemand to prevent it from being called from untrusted code; only the immediate caller is required to have SecurityPermissionAttribute.UnmanagedCode permission. If your code can be called from partially trusted code, do not pass user input to Marshal class methods without validation. For important limitations on using the LinkDemand member, see Demand vs. LinkDemand.
