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;

    public partial class form1 : form

            initializecomponent();
        }

                mheight = convert.toint32(myobject["loadpercentage"].tostring());
                if (mheight == 100)
