.net c#获取磁盘当前总空间和可用空间

查询当前电脑的磁盘空间,并给于提示,是一个完善软件的标配.

1.首先查询系统的盘符

            SelectQuery selectQuery = new SelectQuery("select * from win32_logicaldisk");
            ManagementObjectSearcher searcher = new ManagementObjectSearcher(selectQuery);
            foreach (ManagementObject disk in searcher.Get())
            {
                zcmb.Items.Add(disk["Name"].ToString());
            }
            if (zcmb.Items.Count > 0) { zcmb.SelectedIndex = 0; }

2.查询每隔盘符的空间情况

        private void zcmb_SelectedIndexChanged(object sender, EventArgs e)
        {
            string name = zcmb.Text;
            if (string.IsNullOrEmpty(name)) { return; }
            DriveInfo dinfo = new DriveInfo(name);
            ztol.Text = "总容量：" + FormatFileSize(dinfo.TotalSize);
            zhas.Text = "剩余容量：" + FormatFileSize(dinfo.TotalFreeSpace);
        }
