Answer 1

用System.Diagnostics.Process.GetProcessesByName，System.Diagnostics.Process.GetProcessById试试

Answer 2

Process.GetProcesses()获得全部process实例

Answer 3

Process[] process  = Process.GetProcesses();
foreach(Process p in process)
{
  this.label1.Text += p.ProcessName +"\n" ;
}

Answer 4

foreach (Process oth in Process.GetProcesses())
            {
                //this.richTextBox1.AppendText(oth.ProcessName+"\n");
                if (oth.ProcessName.ToUpper() == "QQ")
                {
                    this.richTextBox1.AppendText(oth.ProcessName + "\n");
                    this.richTextBox1.AppendText(oth.Id.ToString()+"\n");
                }
            }
