In C#, dealing with null values is a common scenario, and to handle them more effectively, C# provides several null operators. These operators help developers write cleaner and more concise code when dealing with nullable values. Null operators in C# are used to handle null values more efficiently and safely. They help prevent null reference exceptions and make code more concise.
There are several null operators available in C#:
Null Coalescing Operator (??
)
