002-进程信息

获取进程信息

(1)获取本地计算机的所有进程:
Process[] myProcesses = Process.GetProcesses();

(2)获取本地计算机上指定名称的进程:
Process[] myProcesses =
Process.GetProcessesByName("进程名称");
注意:(a)进程名称不带扩展名。(b)可以是任何一个可执行文件
例如:
Process[] myProcesses = Process.GetProcessesByName (“WindowApplication1");

(3)获取远程计算机的所有进程:
Process[] myProcesses =
Process.GetProcesses (remoteMachineName);
例如:
Process[] myProcesses = Process.GetProcesses ("192.168.0.1");

(4)获取远程计算机上指定名称的进程:
Process[] myProcesses = Process.GetProcessesByName( "远程进程名称",remoteMachineName);

本机运行的所有进程,并显示进程相关的信息。

效果如下

示例代码

       Process[] myProcess;
      //得到多有进程
       private void GetAllProcess()
        {
            dataGridView1.Rows.Clear();
            myProcess = Process.GetProcesses();
            foreach (Process p in myProcess)
            {
                int newRowIndex = dataGridView1.Rows.Add();
                DataGridViewRow row = dataGridView1.Rows[newRowIndex];
                row.Cells[0].Value = p.Id;
                row.Cells[1].Value = p.ProcessName;
                row.Cells[2].Value = string.Format("{0:###,##0.00}MB", p.WorkingSet64 / 1024.0f / 1024.0f);
                //有些进程无法获取启动时间和文件名信息,所以要用try/catch
                try
                {
                    row.Cells[3].Value = string.Format("{0}", p.StartTime);

            }
        }
        //查看进程信息
        private void ShowProcessInfo(Process p)

                if (p.Modules != null)
                {
                    ProcessModuleCollection pmc = p.Modules;
                    sb.AppendLine("调用的模块(.dll):");
                    for (int i = 1; i < pmc.Count; i++)
                    {
                        sb.AppendLine(

            }
