.NET (Core and Framework)

With user-defined types and Object variables, the Len function returns the size as it will be written to the file by the FilePut function. If an Object contains a String, it will return the length of the string. If an Object contains any other type, it will return the size of the object as it will be written to the file by the FilePut function.

Although you can use the SizeOf[^] method, the value returned by this method is not always the same as the value returned by sizeof. Marshal.SizeOf returns the size after the type has been marshaled whereas sizeof returns the size as it has been allocated by the Common Language Runtime, including any padding.

I have found some information that says that this method is bugged because using -1 as timeout (i.e. block forever) returns immediately. The problem is that this information is a bit old and I can not find any place saying it is fixed.
