实现
新建一个窗体页面,设计布局如下
左边cpu使用是两个panel,右边是pregressbar,下面是statusstrip,然后在页面添加一个timer,
然后修改其代码如下
using system; using system.collections.generic; using system.componentmodel; using system.data; using system.drawing; using system.linq; using system.text; using system.windows.forms; using system.diagnostics; using system.threading; using system.runtime.interopservices; using system.management; namespace cpu_detect { public partial class form1 : form { public form1() { initializecomponent(); } process[] myprocesses; thread td; private void myuser() { managementobjectsearcher searcher = new managementobjectsearcher("select * from win32_processor"); foreach (managementobject myobject in searcher.get()) { tssluse.text = myobject["loadpercentage"].tostring()+" %"; lblcpu.text = myobject["loadpercentage"].tostring() + " %"; mheight = convert.toint32(myobject["loadpercentage"].tostring()); if (mheight == 100) panel3.height = 100; createimage(); memory(); } } private void memory() { microsoft.visualbasic.devices.computer myinfo = new microsoft.visualbasic.devices.computer(); //获取物理内存总量 pbmemorysum.maximum = convert.toint32(myinfo.info.totalphysicalmemory/1024/1024); pbmemorysum.value = convert.toint32(myinfo.info.totalphysicalmemory / 1024 / 1024); lblsum.text = (myinfo.info.totalphysicalmemory / 1024).tostring(); //获取可用物理内存总量 pbmemoryuse.maximum = convert.toint32(myinfo.info.totalphysicalmemory / 1024 / 1024); pbmemoryuse.value = convert.toint32(myinfo.info.availablephysicalmemory / 1024 / 1024); lblmuse.text = (myinfo.info.availablephysicalmemory / 1024).tostring(); //获取虚拟内存总量 pbvmemorysum.maximum = convert.toint32(myinfo.info.totalvirtualmemory / 1024 / 1024); pbvmemorysum.value = convert.toint32(myinfo.info.totalvirtualmemory / 1024 / 1024); lblvinfo.text = (myinfo.info.totalvirtualmemory / 1024).tostring(); //获取可用虚拟内存总量 pbvmemoryuse.maximum = convert.toint32(myinfo.info.totalvirtualmemory / 1024 / 1024); pbvmemoryuse.value = convert.toint32(myinfo.info.availablevirtualmemory/ 1024 / 1024); lblvuse.text = (myinfo.info.availablevirtualmemory / 1024).tostring(); } private void form1_load(object sender, eventargs e) { checkforillegalcrossthreadcalls = false; myprocesses = process.getprocesses(); tsslnum.text = myprocesses.length.tostring(); myuser(); } private void timer1_tick(object sender, eventargs e) { myprocesses = process.getprocesses(); tsslnum.text = myprocesses.length.tostring(); td = new thread(new threadstart(myuser)); td.start(); } private void form1_formclosed(object sender, formclosedeventargs e) { if (td != null) { td.abort(); } } int mheight = 0; private void createimage() { int i=panel3.height/100; bitmap image = new bitmap(panel3.width,panel3.height); //创建graphics类对象 graphics g = graphics.fromimage(image); g.clear(color.green); solidbrush mybrush = new solidbrush(color.lime); g.fillrectangle(mybrush,0,panel3.height-mheight*i,26,mheight*i); panel3.backgroundimage = image; } } }
