'Snake_Case to PascalCase with regex

I Have a C# project where the class properties are all in Snake_Case, I want to convert them to PascalCase as recommended by Capitalization Conventions

also, the parameter names are in snake_Case and I'm using angular on the frontend and during deserialization, these properties are converted to snake_Case I want to convert snake_Case to pascalCase

I'm using VS code so I wanna use the search and replace functionality

e.g

Snake_Case --> SnakeCase

snake_Case --> snakeCase

i have tried:

([a-z])_([A-Z])
$1$2

but that does not work on GG_Registration_Number is becomes GG_RegistraionNumber

Solution 1:[1]

G is in upper case, ([a-z]) only captures lower case.

Use

([a-zA-Z])_([A-Z])
