C#检查远程或本地磁盘使用率

因为公司有多个服务器，要检查磁盘的使用情况确定程序放哪个服务器和清理垃圾,所以写个小程序帮忙检查。

效果图:

后台代码:

private void btncheck_click(object sender, eventargs e)
{
listbox1.items.clear();
if (rbtnremote.checked)
{
//远程
remotedisk();
}
else
{
//本地
localdisk();
}
}
//查看本地
private void localdisk()
{
wqlobjectquery wmiquery = new wqlobjectquery("select * from win32_logicaldisk");
managementobjectsearcher wmifind = new managementobjectsearcher(wmiquery);
//显示
showinfo(wmifind);
}
//远程
private void remotedisk()
{
if (cbip.text == "" | cbusername.text == "" | txtpwd.text == "")
{
messagebox.show("请把信息补充完整!");
return;
}
string ip = cbip.text;
string username = cbusername.text;
string password = txtpwd.text;
connectionoptions conn = new connectionoptions();
conn.username = username;
conn.password = password;
conn.timeout = new timespan(1,1,1,1);//连接时间
//managementscope 的服务器和命名空间。 
string path = string.format(@"\\{0}\root\cimv2", ip);
//表示管理操作的范围（命名空间）,使用指定选项初始化managementscope 类的、表示指定范围路径的新实例。 
managementscope scope = new managementscope(path, conn); 
scope.connect(); 
//查询
string strquery = "select * from win32_logicaldisk ";
objectquery query = new objectquery(strquery);
//查询managementobjectcollection返回结果集 
managementobjectsearcher wmifind = new managementobjectsearcher(scope, query);
showinfo(wmifind);
}
#region 显示磁盘信息

//判断是否是本机固盘
