Log4net 以编程方式配置 adoAppender

我需要在现有的log4net配置中添加一个ado appender。
我需要通过代码添加它。但是,我坚持添加常见的字符串参数,例如消息,因为我无法正确定义布局属性:在xml配置中,我们使用PatternLayout,但是通过代码PatternLayout不是IRowLayout,因此我遇到以下代码的错误:
public static void AddStringParameterToAppender(this log4net.Appender.AdoNetAppender appender, string paramName, int size, string conversionPattern)
{
log4net.Appender.AdoNetAppenderParameter param = new log4net.Appender.AdoNetAppenderParameter();
param.ParameterName = paramName;
param.DbType = System.Data.DbType.String;
param.Size = size;
param.Layout = new log4net.Layout.PatternLayout(conversionPattern);
appender.AddParameter(param);
}
有人知道如何在代码中添加类似于以下xml示例的字符串参数吗:
<parameter>
<parameterName value="@message" />
<dbType value="String" />
<size value="4000" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%message" />
</layout>
</parameter>
我终于找到了如何在IRawLayout
中转换PatternLayout
。
为此,您必须使用log4net.Layout.Layout2RawLayoutAdapter
:
public static void AddStringParameterToAppender(this log4net.Appender.AdoNetAppender appender, string paramName, int size, string conversionPattern)
{
log4net.Appender.AdoNetAppenderParameter param = new log4net.Appender.AdoNetAppenderParameter();
param.ParameterName = paramName;
param.DbType = System.Data.DbType.String;
param.Size = size;
param.Layout = new log4net.Layout.Layout2RawLayoutAdapter(new log4net.Layout.PatternLayout(conversionPattern));
appender.AddParameter(param);
}
