我开始使用parameters.xml文件替换WebAPI中web.config文件中的值。使用此方法取得了一些成功，并且能够替换如下所示配置的AppSettings部分中的值：-
<?xml version="1.0" encoding="utf-8"?>

</parameter>
</parameters>
对于我定位的appsettings部分来说，这一切都很好，请忽略web.config文件中的任何错误，因为我从连接字符串等中删除了一些敏感信息，但是连接字符串或类似的东西都没有问题
我面临的问题是参考NLog配置部分，在该部分中，我尝试使用与web.config中appsettings部分相同的技术进行替换，但是由于某些原因，不行。
在如上所示的parameters.xml文件中，我有以下部分针对我的web.config中的Nlog部分：-
<parameter name="minlevel"
description="Specify the Nlog minimum logging level"
defaultValue="__SWAPNLOGLEVEL__">
<parameterEntry kind="XmlFile" scope="Web.config"
match="/configuration/nlog/rules/logger[@writeTo="databaseTarget"]/@minlevel" />
在我的Web配置中，我有Nlog部分，如下所示：-
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd" autoReload="true" throwExceptions="false" internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log">
<variable name="myvar" value="myvalue" />
<targets>
<target name="fileTarget" xsi:type="File" fileName="C:\logs\seller.log" layout=" -------------- ${level} (${longdate}) --------------${newline} ${newline} Call Site: ${callsite}${newline} Exception Type: ${exception:format=Type}${newline} Exception Message: ${exception:format=Message}${newline} Stack Trace: ${exception:format=StackTrace}${newline} Additional Info: ${message}${newline}" />
<target name="databaseTarget" xsi:type="Database" connectionStringName="NLog" commandText="exec dbo.InsertLog @level, @callSite, @type, @message, @stackTrace, @innerException, @additionalInfo, @machineName, @process, @appDomain, @appId, @appGrouping, @loggedOnDate">
<parameter name="@level" layout="${level}" />
<parameter name="@callSite" layout="${callsite}" />
<parameter name="@type" layout="${level}" />
<parameter name="@message" layout="${message}" />
<parameter name="@stackTrace" layout="${stacktrace}" />
<parameter name="@innerException" layout="${exception}" />
<parameter name="@additionalInfo" layout="" />
<parameter name="@machineName" layout="${machinename}" />
<parameter name="@process" layout="${processname}" />
<parameter name="@appDomain" layout="${appdomain}" />
<parameter name="@appId" layout="0" />
<parameter name="@appGrouping" layout="0" />
<parameter name="@loggedOnDate" layout="${date}" />
</target>
</targets>
<rules>
<logger minlevel="Trace" name="*" writeTo="databaseTarget" />
</rules>
</nlog>
我的目标是更改节点
<logger minlevel="Trace" name="*" writeTo="databaseTarget" />
到
<logger minlevel="__SWAPNLOGLEVEL__" name="*" writeTo="databaseTarget" />
，但是由于某种原因，该节点不受影响。我已经在notepad ++中测试了我的Xpath，它能以与识别appsettings属性相同的方式正确识别该属性，但是不会发生任何修改。
我对Web部署过程等并不十分熟悉，但是我设法在Internet上找到的所有内容似乎都证实了该方法可以正常工作，因此我们将不胜感激。
