Obtain the system process and end a specified process.

See this articleArticleTo disable the specified ie instance:
Http://www.c-sharpcorner.com/Code/2002/Mar/CaptRunIEInstances.asp

I thought of another way to do this.

Modify the Registry first:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ service \ perfproc \ Performance
The value of disable performance counters is changed to 0.

Get the current process of the system and add it to ListBox:
System. Diagnostics. Process [] processoncomputer = system. Diagnostics. process. getprocesses ();
Foreach (system. Diagnostics. Process P in processoncomputer)
{
This. listbox1.items. Add (P. processname );
}

Shut down a specified process:
System. Diagnostics. Process [] process = system. Diagnostics. process. getprocessesbyname (this. listbox1.selecteditem. tostring ());

Foreach (system. Diagnostics. Process P in process)
{
P. Kill ();
}

However, this will close all instances of the process. For example, if you open multiple ie instances, all IE Windows will be closed.

The following code disables a specific ie instance:
Declare An arraylist first:
Arraylist tables whandle = new arraylist ();

Get all the instances of the specified process, put them in a ListBox, and put the handle of the main window into arraylist:
System. Diagnostics. Process [] processoncomputer = system. Diagnostics. process. getprocessesbyname (this. listbox1.selecteditem. tostring ());
Foreach (system. Diagnostics. Process P in processoncomputer)
{
This. listbox2.items. Add (P. mainwindowtitle); // display the title of the main form in ListBox
Define whandle. Add (P. main1_whandle );
}

compare the handle in the main window of the specified process with that in arraylist. If yes, disable
system. diagnostics. process [] process = system. diagnostics. process. getprocessesbyname (this. listbox1.selecteditem. tostring ();
foreach (system. diagnostics. process P in process)
{< br> If (P. main1_whandle = (system. intptr) (when whandle [this. listbox2.selectedindex])
{< br> P. kill ();
This. listbox2.items. removeat (this. listbox2.selectedindex);
}< BR >}< br>
in this way, the process with the main form can be closed, however, it does not work if there is no main form.
Please advise me more
