从web.config system.web部分检索值

Question

In my .net application web.config file, under the system.web section,

<system.web>
     <membership configSource="membership.config" />
</system.web>

and in my membership.config file:

<?xml version="1.0" encoding="utf-8"?>
<membership defaultProvider="MembershipProvider">
    <add applicationName="xxx"  
         testing="3" />
 </providers>
</membership>

In my application code, how do I get the value for "testing"?

Answer 1

If you use build-in SqlMembershipProvider:

var appName = ((SqlMembershipProvider) Membership.Provider).ApplicationName;

If you implement your own custom membership provider, you can get the value from Initialize method Eg:

public class YouMembershipProvider: MembershipProvider
{
public override void Initialize(string name, System.Collections.Specialized.NameValueCollection config)
{
     var appName = config["applicationName"];
}

Your configuration should looks like following:

<?xml version="1.0" encoding="utf-8"?>
<membership defaultProvider="myMembershipProvider">
    <add name="myMembershipProvider" type="TestApp.YouMembershipProvider, TestApp" ApplicationName="xxx"/>
 </providers>
</membership>
