Debugging in C#

Theory on understanding debugging.

Debugging

The process of identifying, analyzing, and removing errors (bugs) in software.

Syntax Errors

Mistakes in the use of the programming language.

Runtime Errors

Errors that occur during the execution of the program.

Logic Errors

Errors in the algorithm or logic that produce incorrect results.

Manual Debugging

Reviewing code line-by-line to find errors.

Print Statements

Using Console.WriteLine to output variable values and program flow.

Debugger Tools

Using an Integrated Development Environment (IDE) like Visual Studio for debugging.

Breakpoints

Pausing the execution at specific points to inspect the state.

Isolate the Problem

Narrow down the code area where the bug occurs.

Understand the Code

Thoroughly understand the code and its expected behavior.

Use Version Control

Keep track of code changes to identify when bugs were introduced.

Write Test Cases

Create tests to cover different scenarios and edge cases.

NullReferenceException

Occurs when trying to access an object that is null.

IndexOutOfRangeException
