Use a program to start multiple programs at the same time (C #)

The fat boy in the dormitory needs to run multiple Program He wanted a program to implement these things, so he wrote a program. Could you give me any comments? I will make more modifications. Thank you and paste the source code:
Using system;
Using system. Collections. Generic;
Using system. componentmodel;
Using system. Data;
Using system. drawing;
Using system. text;
Using system. Windows. forms;
Using system. diagnostics;
Using system. IO;
Namespace lazy Program
{
Public partial class form1: Form
{
Public form1 ()
{
Initializecomponent ();
}
Private void form1_load (Object sender, eventargs E)
{
System. Diagnostics. processstartinfo info = new system. Diagnostics. processstartinfo ();
Info. useshellexecute = true;
Process P;
String Path = @ "C: \ a.txt ";
Filestream FS = new filestream (path, filemode. Open, fileaccess. Read );
Streamreader sr = new streamreader (FS, encoding. Default );
String RL;
While (RL = Sr. Readline ())! = NULL)
{
Info. filename = RL;
// Richtextbox1.appendtext (RL + '\ n ');
P = process. Start (Info );
}
Sr. Close ();
FS. Close ();
Application. Exit ();
}
}
}
Instructions for use: install the software first, and create a.txt file in the C-root directory before running. Then, take the detailed path of the program to be run simultaneously, including the program name and exe suffix, and one program occupies one line. Multiple lines can exist at the same time. For example:
C: \ Program Files \ Internet Explorer \ ipolice.exe
C: \ Program Files \ Internet Explorer \ ipolice.exe
