How to Fix: C# catch a stack overflow exception

C# stack overflow exception handling

Quick Answer: A stack overflow exception cannot be caught using a try-catch block. Instead, use the "catch" keyword with the "StackOverflowException" type to handle it.

A stack overflow exception in C# typically occurs when a method calls itself recursively without any base case to stop the recursion. This can lead to a huge number of function calls, eventually exceeding the maximum stack size allowed by the runtime.

🚀 How to Resolve This Issue

Method 1: Use Recursion with a Base Case

  1. Step 1: Identify the recursive method and add a base case to stop the recursion.

Method 2: Use Iteration Instead of Recursion

  1. Step 1: Replace the recursive method with an iterative solution using a loop.
