C# Beginner to advanced - Lesson 33 - Implicit & Explicit Conversion & Diff between Parse & TryParse

Implicit and Explicit Conversion and Difference between Parse and TryParse

Type conversion is converting one type of data to another type. It is also known as Type Casting. In C#, type casting has two forms:

Implicit Conversion : Implicit Conversion is done by the compiler :

When there is no loss of information if the conversion is done.

If there is no possibility of throwing exceptions during the conversion.

Example : Converting an int to float will not loose any data and no exception will be thrown, hence an implicit conversion can be done

Explicit Conversion : Explicit Conversion is done by the user :

For Explicit conversion we can use cast operator or the convert class in C#

Example : Converting an float in to int , we loose the fractional part and also a possibility of overflow exception.

If we want to convert number in string format to other numerical formats like int ,decimal, float then we have two options:

Parse()

TryParse().

Parse() Method throws an exception if it cannot parse the value.

TryParse() Method returns a bool indicating whether it succeeded or failed

Use parse() if you are sure the value will be valid, otherwise use TryParse()
