I used this code:

switch ((sender as ContextMenuStrip).SourceControl.Name)

            {

                case "listViewH":

                    CopyListViewToClipboard(listViewH);

                    break;

                case "listViewData":

                    CopyListViewToClipboard(listViewData);

                    break;

                case "listViewSys":

                    CopyListViewToClipboard(listViewSys);

                    break;

                case "listViewMem":

                    CopyListViewToClipboard(listViewMem);

                    break;

                case "listViewNet":

                    CopyListViewToClipboard(listViewNet);

                    break;

                case "listViewUser":

                    CopyListViewToClipboard(listViewUser);

                    break;

                case "listViewDev":

                    CopyListViewToClipboard(listViewDev);

                    break;

                case "listViewUlt":

                    CopyListViewToClipboard(listViewUlt);

                    break;

            }

or i try this:

CopyListViewToClipboard((ListView)(sender as ContextMenuStrip).SourceControl);

And i am getting "Object reference not set to an instance of an object.".

You need to copy the whole code, but my money is some of those list are initialized either as objets or have null content and your CopyListViewToClipboard method is not checking for it.

I guess the problem is in (ListView)(sender asContextMenuStrip). First you converted a ListView (sender as ContextMenuString) to ContextMenuStrip which should not happen as ListView is NOT a base-class of ContextMenuStrip.

I think the code will work if you omit the (ListView) casting part.
