AttachMovie、RemoveMovieAS2、C#get swf root value

[cong1991007]

Hi~
i have three question：
1) how could i get the swf movie root,in c#.
i had try to use GetVariable(, ) function to get my root ,but it doesn't work .
2）how could i create a movieClip in C#.
i used AS3.0 make a swf ,I had try to use AttachMovie ,but it can't work.
3) i found a mistake in RemoveMovieAS2() ;
in RemoveMovieAS2() function ,script call Invoke("removeMovie",null) to remove movie ,because the second param is null ,so in Invoke() function param objs can't get the length ,then it through an error.

Waiting for reply ,thank you..
