FAQs on Part 59 C# Tutorial Difference between Convert ToString and ToString Video Lecture - C sharp: Enhance your Skills (English) - Back-End Programming

1. What is the difference between Convert.ToString() and ToString() in C#?
Ans. The main difference between Convert.ToString() and ToString() in C# is their usage and what they can convert. Convert.ToString() is a static method that can convert any object to its string representation, including null values. On the other hand, ToString() is an instance method that is typically overridden in classes to provide a custom string representation of the object. It can only convert the specific object it is called on.
2. Can Convert.ToString() be used to convert primitive data types in C#?
Ans. Yes, Convert.ToString() can be used to convert primitive data types in C#. For example, you can use Convert.ToString(123) to convert an integer value to its string representation. Convert.ToString() handles the conversion of various data types and provides appropriate string representations.
3. Is it possible to override ToString() method in C#?
Ans. Yes, it is possible to override the ToString() method in C#. ToString() is a virtual method defined in the base Object class, which means it can be overridden in derived classes to provide a custom string representation. By overriding ToString(), you can control how your object is represented as a string when it is converted using ToString().
4. Can Convert.ToString() handle null values in C#?
Ans. Yes, Convert.ToString() can handle null values in C#. When null is passed to Convert.ToString(), it returns an empty string ("") instead of throwing an exception. This behavior can be useful when dealing with nullable types or when converting objects that may be null.
5. Which method should I use, Convert.ToString() or ToString(), in C#?
Ans. The choice between Convert.ToString() and ToString() depends on the specific scenario and the type of object you want to convert. If you want a generic method that can convert any object to its string representation, including null values, you can use Convert.ToString(). However, if you want to provide a custom string representation for a specific object or class, you should override the ToString() method and implement your own logic.
