An Effective way to Eliminate null Exception in C# 🚀Programming

Handling null references effectively is crucial in C# programming to avoid NullReferenceException errors.

Here are some effective ways to manage null references:

1. Null Coalescing Operator (??)

The null coalescing operator provides a concise way to handle null values by specifying a default value if the expression is null.

string result = someNullableString ?? "default value";

2. Conditional Access Operator (?.)

The conditional access operator allows you to safely access members of a potentially null object without causing a NullReferenceException.

int? length = someObject?.Name?.Length;

3. Null Conditional Operator with Method Invocation (?.)

You can use the null conditional operator when invoking methods on objects that may be null.

int? count = someList?.Count();

4. Checking for Null

Explicitly check for null before accessing properties or invoking methods to ensure safety.
