如何以编程方式编辑nlog配置文件 [英] how to edit the nlog config file programmatically

问题描述

我正在尝试以编程方式在配置文件中编辑日志记录级别.

i am trying to edit the logging level in the config file programmaticly.

 foreach (var rule in LogManager.Configuration.LoggingRules)
    {


                if (m_loginglevelcomboBox.SelectedItem.ToString() == "Debug")
                {
                    rule.EnableLoggingForLevel(LogLevel.Debug);
                }
                else
                {
                    rule.EnableLoggingForLevel(LogLevel.Info);

                }
     }

            //LogManager.ReconfigExistingLoggers();

我对调用Reconfig并不感兴趣，因为更改会即时影响应用程序. 我希望在重新启动应用程序时进行更改.所以我需要它来编辑配置文件.

I am not interested in calling the Reconfig,as the changes will affect the application on the fly. I want the changes to be made when the application is restarted. so I need it to edit the config file.

我不能使用xDocument，因为linq与我的.net版本不兼容 所以我该如何编辑最小级别规则来调试/信息?

i cant use xDocument ,as linq is not compatible with my .net version so how can i edit the minlevel rule to debug/info ?

推荐答案

i用它来编辑日志记录级别.我希望如果有人偶然发现这对您有帮助.如果有人认为这是个坏主意，请告诉我.

i used this to edit the logging level. I hope if this would help if some one stumbles across. If some one thinks it to be a bad idea, please let me know .

            string configFilename = GetConfigFilePath();


            XmlDocument doc = new XmlDocument();
            doc.Load(configFilename);

            XmlNode documentElement = doc.DocumentElement;

            foreach (XmlNode node in documentElement.ChildNodes)
            {
                if (ruleDocumentNodeName.Equals(node.Name))
                {
                    foreach (XmlNode childNode in node.ChildNodes)
                    {
                        if (loggerDocumentNodeName.Equals(childNode.Name))
                        {
                            XmlAttribute idAttribute = childNode.Attributes[minLevelAttributeName];
                            string currentValue = minLogingLevelComboBox.SelectedItem.ToString();
                            idAttribute.Value = currentValue;
                            doc.Save(configFilename);
                            MinLoggingLevelChanged = true;
                        }
                    }
                }
            }
