Hi,
Last week I got a new task i.e. in the web part it should display all the sub sites under the site collection.
If user has an access to the sub site, then it should display only Site Name, description and
If user hasn't got access to the site, then it should display only Site Name, description along with ‘Request To Join’ as below
If user clicks ‘Request To Join’ button, email has to be triggered to User group ‘Key Contacts’ members and maiBody,subject should be fetched from ‘EmailConfigurations’ list.
In that list, there will be column name as ‘Community Site Request To Join’
Mail Body, Mail Subject details should be fetched from the row as below
Below is the code that has been written to achieve this functionality

Testing
Coming to testing part,before testing below steps have been followed to view the result
1. User id needs to be added as site collection administrator
2. User id needs to be added in the ‘Owner’ group of the site collection
3. In all the subsites ‘Stop inheriting permissions’ have been removed all groups have been removed by ‘Remove permissions’
4. In some subsites User id has been added by providing ‘Full Control’
5. User id has been removed as administrator of the site collection and web part has been added to site collection page
