I add a section in Web.config as follow:

<section name="ApplicationConfiguration" type="RTankManager.SystemFramework.ApplicationConf iguration, RTankManager.SystemFramework" />
<ApplicationConfiguration>

    <!--

        To enable tracing do the following:
            1. Set the SystemFramework.Tracing.Enabled value to "True"
            2. Be sure the file identified by SystemFramework.Tracing.TraceFile exists, if not create it
            3. Place an ACL on the file allowing full access to [machine name]\ASPNET
            4. Restart IIS

    -->
    <add key="SystemFramework.Tracing.Enabled" value="False" />

    <add key="SystemFramework.Tracing.TraceFile" value="C:\Documents and Settings\zhangmin\My Documents\Visual Studio Projects\RTankManager\RTankManager\.\RTankTrace.tx t" />

    <add key="SystemFramework.Tracing.TraceLevel" value="4" />
    <!-- This switch name. The trace level for this name can be set through
             environment variables or the registry -->
    <add key="SystemFramework.Tracing.SwitchName" value="RTankTraceSwitch" />

    <add key="SystemFramework.Tracing.SwitchDescription" value="Error and information tracing for Rtank" />
    <!-- Event log settings
    Note: The default Duwamish7 event source name is created in the local machine during setup. If you wish to log events to a different event source
             that event source must exist.
        -->
    <add key="SystemFramework.EventLog.Enabled" value="True" />
    <add key="SystemFramework.EventLog.Machine" value="." />
    <add key="SystemFramework.EventLog.SourceName" value="RTank" />
    <!-- Use the standard TraceLevel values:
             0 = Off
             1 = Error
             2 = Warning
             3 = Info
             4 = Verbose -->
    <add key="SystemFramework.EventLog.LogLevel" value="1" />
</ApplicationConfiguration>



when I call Fuction "System.Configuration.ConfigurationSettings.GetCon fig("ApplicationConfiguration")" in ApplicationConfiguration,
there is a error .Why?

Hi there,

I think you're better off posting this question in one of the ASP.NET forums. This forum is for general feedback about this site, and not for technical questions.....

If you do repost your question, you may want to elaborate a bit about what you are trying to accomplish.

Cheers,

Imar
