How to access to user defined class in .NET MAUI contentpage

Question

Hi All,

I have defined a class ContactInfo.cs and would like the class to be accessible by all the contentpage in my .NET MAUI project.

Please let me know how to do it.

Hello,

It is recommended to use thread-safe singleton mode to achieve this functionality.

Please refer to the following code:

   public class ContactInfo  
   {  
       private static ContactInfo instance = null;  
       private static readonly object obj = new object();  
       public static ContactInfo Instance  
       {  
           get  
           {  
               lock (obj)  
               {  
                   if (instance == null)  
                   {  
                       instance = new ContactInfo();  
                   }  
                   return instance;  
               }  
           }  
       }  
   }  

Then, you could use ContactInfo.Instance to use this object by all the contentpage.
