.net中调用windows performance记录性能信息

记录skype的cpu 占用率
 
var processorcounter = new performancecounter
{
       categoryname = "process",
       countername = "% processor time",
       instancename = “skype”,
       machinename = "."
};

processorcounter.nextvalue()
 
 
 记录skype的内存占用
 
var memorycounter = new performancecounter
{
    categoryname = "process",
    countername = "working set - private",
    instancename = “skype”,
    machinename = "."
};

memorycounter.rawvalue  返回的是字节为计量单位
 
获取当前计算计算机的cpu和内存占用情况
 
counter = new performancecounter("processor", "% processor time", “_total”);

counter.nextvalue() cpu占用

computerinfo computerinfo = new computerinfo();

computerinfo.totalphysicalmemory - computerinfo.availablephysicalmemory 内存占用
 
注意， 使用counter的时候，如果instancename 不存在， 会出现异常。
