What methods exist for causing a stack overflow during program execution?

Stack overflow in C# is usually caused by infinite or excessively deep recursion. Main methods that lead to stack overflow:

• Infinite recursion: a function calls itself without an exit condition.

void Recursive()
{
    Recursive(); // call without exit condition
}

Recursive();

• Deep recursion: recursive calls with a large number of nested calls exceeding the stack size.

• Creating large local variables: declaring very large local arrays or structures can lead to stack overflow, but this is less common.

Stack overflow results in a StackOverflowException in .NET, which cannot be caught or handled in code.
