c＃set performanceCounters enabled = true代码

Question

我正在使用此方法来计算我的app发送字节数：

string currId = Process.GetCurrentProcess().Id.ToString();

            PerformanceCounter dataSentCounter = new PerformanceCounter();
            dataSentCounter.CategoryName=".NET CLR Networking";
            dataSentCounter.CounterName="Bytes Sent";
            dataSentCounter.InstanceName =  "curr"+"["+currId+"]";
            dataSentCounter.ReadOnly = true;

            float sumSent = 0;
            sumSent = dataSentCounter.NextValue();

            uploadSize_Label.Content = sumSent.ToString();

它适用于app.config：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
    <settings>
        <performanceCounters enabled="true"/>
    </settings>
</system.net>
</configuration>

是否可以在不使用app.config的情况下设置performanceCounters enabled="true"（没有任何配置文件 - 只能通过应用程序代码）？

您应该可以使用PerformanceCountersElement.Enabled属性。

        System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        NetSectionGroup netGroup = (NetSectionGroup)config.SectionGroups.Get("system.net");
        netGroup.Settings.PerformanceCounters.Enabled = true;

        config.Save(ConfigurationSaveMode.Modified);
