输入初始化错误 [英] Type initialization error

问题描述

我收到以下错误

'System.Windows.Application'的类型初始值设定项引发异常 
 
 
 
。这是一个WPF应用程序。
 
 
 
 
 <？  xml     version   =  1.0    encoding   =  utf-8   ？ >

我还是找不到这个配置文件有什么问题。没有log4net配置它工作正常。任何评论都非常感谢。
解决方案
 
我找到了解决方案，我错过了log4net的配置。以下需要在log4net标记之前的app.config中。
 
 
 
 
 < ;   configsections  >  
  <   section     name   =  log4net    type   =  log4net.Config.Log4NetConfigurationSectionHandler，Log4net < span class =code-attribute>   /  >  
 <   / configsections  >  
 
 
 
I got the following error



The type initializer for 'System.Windows.Application' threw an exception




when I've the following content in app.config file. This is a WPF application.



<?xml version="1.0" encoding="utf-8" ?>
<configuration>
	<log4net>
		<appender name="RollingFileAppenderV1" type="log4net.Appender.RollingFileAppender">
			<file type="log4net.Util.PatternString" value="xxxzzzlog.txt"/>
			<appendToFile value="true"/>
			<rollingStyle value="Size"/>
			<maxSizeRollBackups value="50"/>
			<maximumFileSize value="100KB"/>
			<staticLogFileName value="true"/>
			<countDirection value="1"/>
			<layout type="log4net.Layout.PatternLayout">
				<param name="ConversionPattern" value="[%d{yyyy-MM-dd hh:mm:ss}] - [%-5p] – %m%n"/>
			</layout>
		</appender>
		<root>
			<level value="ALL"/>
			<appender-ref ref="RollingFileAppenderV1"/>
		</root>
	</log4net>
	<startup>
		<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
	</startup>
</configuration>




Still I couldn't find what's wrong with this config file. Without the log4net configuration it works fine. Any comments really appreciate.
解决方案
I Found the solutions, I've miss the configuration for log4net. Following need to be in the app.config just before the log4net tag.



<configsections>
	<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net" />
</configsections>
