C# 获取系统进程
using System.Diagnostics;using System.Management;static void Main(string args){foreach (Process p in Process.GetProcesses()) { Console.Write(p.ProcessName); Console.Write(“----“); Console.WriteLine(GetProcessUserName(p.Id)); } Console.ReadKey();}private static string GetProcessUserName(int pID){ string text1 = null; SelectQuery query1 = new SelectQuery(“Select * from Win32_Process WHERE processID=“ + pID); ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(query1); try { foreach (ManagementObject disk in searcher1.Get()) { ManagementBaseObject inPar = null; ManagementBaseObject outPar = null; inPar = disk.GetMethodParameters(“GetOwner“); outPar = disk.InvokeMethod(“GetOwner“, inPar, null); text1 = outPar[“User“].ToString(); break; } } catch { text1 = “SYSTEM“; } return text1;}
C#用一个下拉列表，在里面显示所有电脑的盘符，急！~~~~
我给你一个最简单的:先创建一个comboBox然后在Form1_Load里输入this.comboBox1.DataSource =System.IO.Directory .GetLogicalDrives ();
