vb6 - What is the equivalent for VB's CreateObject in c# 3.0? -

-

i have below code in vb

private sub refreshcharts() on error goto err_getichelper_refresh     application.cursor = xlwait     dim objoperationrefresh     set objoperationrefresh = createobject("charting.automationproxy")     dim variant     set = application     objoperationrefresh.refreshapplication     application.statusbar = "refreshing .. "     while len(objoperationrefresh.refreshstatus) = 0         doevents     loop     application.statusbar = "refreshing complete."     set objoperationrefresh = nothing     application.statusbar = ""     exit sub err_getichelper_refresh:

i have done conversion in c# except createobject("charting.automationproxy"). equivalent of in c# 3.0?

thanks

you use reflection:

type type = type.gettypefromprogid("charting.automationproxy"); object instance = activator.createinstance(type);

contrary vb , vb.net, c# doesn't support dynamic types until c# 4.0. com object possibility generate typed wrapper simplify usage: in add reference dialog select component com components tab or use tlbimp.exe utility.
