C# implements closing other program windows or process code sharing

During winform development, sometimes you need to close other programs or close processes. I wrote a related introduction article before. Today, a colleague asked about it, so I took it out and shared it with you.

The following are two methods I know, which should be helpful to everyone. If any friends know about other methods, thank you for sharing them.

Method 1
ProcName The name of the process that needs to be closed

private bool closeProc(string ProcName)
{
 bool result = false;
  procList = new ();
 string tempName = "";

 foreach ( thisProc in ())
 {
  tempName = ;
  (tempName);
  if (tempName == ProcName)
  {
   if (!())
(); // Forced end process when sending the closing window command is invalid    result = true;
  }
  }
  return result;
}

The above program defines an ArrayList. When you do not know the specific name of the process you want to close, you can place the value in the ArrayList in a listbox or other control to select the process to end.

Method 2

At the top of the class body:

[DllImport("", CharSet=)]  
public static extern int SendMessage(int hWnd, int msg, int wParam, int lparam);

 //SendMessage(hwnd1,WM_CLOSE,0,0); 
 //hwnd1 is the handle value you return with the findwindow function //wm_close is defined inside //0x0010 is the value of WM_CLOSE SendMessage(hwnd1,0x0010,0,0);
