How to kill process ?

Hi friends,

i want to close process and run every time using for loop ?

But Process run only first time and after that show error process stop , not start next process automatically

DirectoryInfo d = new DirectoryInfo(txtfolderpath.Text);

Files = d.GetFiles("*.kmz").Union(d.GetFiles("*.kml")).ToArray(); //Getting kml,kmz files

str1 = new string[Files.Length];

for (int i = 0; i < Files.Length; i++)

{

str1[i] = Files[i].Name;

// Create new stopwatch.

Stopwatch stopwatch = new Stopwatch();

// Begin timing.

stopwatch.Start();

// Start Google Earth

Process process = Process.Start(txtfolderpath.Text + "\\" + str1[i]);

int timese = Convert.ToInt16(Convert.ToInt16(txttime.Text) * 1000);

// Wait process

Thread.Sleep(timese);

// Stop timing.

stopwatch.Stop();

// Stop Google Earth

process.Kill();

}
