How to resolve "No User Profile Application available to service the request"

When I was trying to get the user properties

ServerContext serverContext = ServerContext.GetContext(site);
UserProfileManager upm = new UserProfileManager(serverContext);
UserProfile up = upm.GetUserProfile(strAccountName);

I was getting the following error. 

  

How to resolve:

• Go to Central Administration => Application Management => Manage Service Applications => User Profile Service Application. 
  
  
  
  
• Click on Administrators => Add the user and give Full Control.
  
  
• Click on Permissions => Add the user and give Full Control.
