C# Winform 进程信息的获取

获取进程信息
1. 如何获取进程信息
（1）获取本地计算机的所有进程
Process [] myProcess = Process.GetProcesses();
（2）获取本地计算机上指定名称的进程
Process [] myProcess = 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 [] myPrecess = Process.GetProcessesByName(“Notopad++”);
（3）获取远程计算机的所有进程：
Process [] myProcess = 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 [] myProcess
= Process.GetProcessesByName(“远程进程名称”,remoteMachineName);

下面写一个winform程序来举例说明：
要求：（1）用DataGridView显示本地计算机所有进程信息
（2）鼠标单击某一行时，显示该行进程的详细信息
