Kill Process Excel C#

Question

I have to 2 process excel. For example:

1) example1.xlsx 2) example2.xlsx

How to kill first "example1.xlsx"?

I use this code:

   foreach (Process clsProcess in Process.GetProcesses())
     if (clsProcess.ProcessName.Equals("EXCEL"))  //Process Excel?
          clsProcess.Kill();

That kill a both. I wanna kill just one... Thank you.

Answer 1

The ProcessMainWindow Title will do it for you, it appends "Microsoft Excel - " to the name of the file:

So essentially (quick code):

private void KillSpecificExcelFileProcess(string excelFileName)
    {
        var processes = from p in Process.GetProcessesByName("EXCEL")
                        select p;

        foreach (var process in processes)
        {
            if (process.MainWindowTitle == "Microsoft Excel - " + excelFileName)
                process.Kill();
        }
    }

Use:

KillSpecificExcelFileProcess("example1.xlsx");

Edit : Tested and verified to work.

Answer 2

kd7's post is an awesome answer and works well, just two things to add,

MainWindowTitle format is - "Filename.xlsx - Excel"

If your excel document is not visible then your MainWindowTitle will be "" using the "" for MainWindowTitle will kill all zombie excel process'.

Answer 3

If your current code is working, this amendment should kill the first process it finds with the name "EXCEL".

foreach (Process clsProcess in Process.GetProcesses())
{
  if (clsProcess.ProcessName.Equals("EXCEL"))
  {
    clsProcess.Kill();
    break;
  }
}

If you want to kill a specific process, you're going to have to give a bit more information.

Copy and paste this. Its done!

 System.Diagnostics.Process[] process = System.Diagnostics.Process.GetProcessesByName("Excel");
     foreach (System.Diagnostics.Process p in process)
     {
         if (!string.IsNullOrEmpty(p.ProcessName))
         {
             try
             {
                 p.Kill();
             }
             catch { }
         }
     }

Answer 5

Excel will always be a single process, AFAIK. The same process/windows opens multiple documents inside it. What you want to do is use Excel automation to CLOSE the document you want to. Perhaps this will get you started. http://support.microsoft.com/kb/302084

Hope this helps.

Use below logic to prevent Zombie Excel processes in Task Manager

 List<int> GetAllExcelProcessID()
    {
       List<int> ProcessID = new List<int>(); 
       if (currentExcelProcessID == -1)
        {
           List<System.Diagnostics.Process> currentExcelProcessList = System.Diagnostics.Process.GetProcessesByName("EXCEL").ToList();
           foreach(var item in currentExcelProcessList)
            {
                ProcessID.Add(item.Id);
            }
        }
       return ProcessID;
    }
int GetApplicationExcelProcessID(List<int> ProcessID1, List<int> ProcessID2)
    {
        foreach(var processid in ProcessID2)
        {
            if (!ProcessID1.Contains(processid)) { currentExcelProcessID = processid; }
        }
        return currentExcelProcessID;
    }
 void KillExcel()
    {
        System.Diagnostics.Process process = System.Diagnostics.Process.GetProcessById(currentExcelProcessID);
        process.Kill();
    }
 List<int> ProcessID1 = GetAllExcelProcessID();
                excel = new Excel.Application();
                List<int> ProcessID2 = GetAllExcelProcessID();
                currentExcelProcessID = GetApplicationExcelProcessID(ProcessID1, ProcessID2);

Answer 7

In the namespace section add this using statement.

using System.Diagnostics;

This example instantiated Excel with this:

_Application excel = new _Excel.Application();

This method kills the right Excel task by using the window handle.

    public void Kill()
    {
        Int32 ExcelHwnd = excel.Hwnd;
        Process[] localExcel = Process.GetProcessesByName("EXCEL");
        foreach (Process Pgm in localExcel)
        {
            // xlMinimized keeps the screen from flashing when the user interface is made 
            // visible with the excel.visible needed to set the MainWindowHandle
            excel.WindowState = XlWindowState.xlMinimized;
            excel.Visible = true;
            if ((Pgm.ProcessName == "EXCEL") && (ExcelHwnd == Pgm.MainWindowHandle.ToInt32()))
            {
                Pgm.Kill();
            }
        }
    }

This worked without fail.

You need to check file handles, that are opened by process and then kill it.
How to check which file handles process is holding: How do I get the list of open file handles by process in C#?

foreach (Process clsProcess in Process.GetProcesses())
{
    if (clsProcess.ProcessName.Equals("EXCEL") && HasFileHandle(fileName, clsProcess))
    {
       clsProcess.Kill();
       break;
    }
 }

Answer 9

Try getting the main window title

   foreach (Process clsProcess in Process.GetProcesses())
   {
      if (clsProcess.ProcessName.Equals("EXCEL")&& clsProcess.MainWindowTitle =="example")  
      {
          clsProcess.CloseMainWindow();
          break;
      }
   }

Answer 10

just did a quick search on Google, try Process.MainWindowTitle() to get the title of the Excel process, and decide which one is that you want to kill.

I am not sure about this method, but hope this will help:
