Are you struggling with null reference exceptions in C#? đźš«đź’»
Don’t let nulls crash into your apps, master these essential tricks to handle them like a pro! 🚀
Use Null-Conditional Operator (?.)
Safely access object members without fear of null reference errors.
Example: int? length = author.Address?.Length;
Null-Coalescing Assignment Operator (??=)
Ensure variables always have a default value.
Example: author.Address ??= "Default Address";
Null-Forgiving Operator (!)
Confidently suppress null warnings and use wisely!
Example: Console.WriteLine(author.Address!);
Conditional Operator (?:)
Assign alternate values when nulls are detected.
Example: string result = author.Address != null ? author.Address : "Unknown";
The is Operator
Verify null values directly and execute code accordingly.
Example:
if (author.Address is not null)
Console.WriteLine(author.Address);
else
Console.WriteLine("Address is null.");
Say goodbye to null errors and write clean and error-free C# code today! đź’ˇ

Thanks for sharing! I would strongly recommend also using the Null Object Pattern to avoid null checks and make the code more maintainable.
