Refactoring Static Methods to Extension methods using Visual Studio 2019 C#

Question

Is there a refactoring available to Refactor Static Methods to Extension methods using Visual Studio 2019 C#? for example I have .string;IsNullOrWhiteSpace( xxx ); in too many places, (1000+ ), I would like to refactor to the extension Method xxx.HasValue(); instead.

Edit: PS: I have the extension method bool HasValue(this string); , just that everywhere in the code people have used .string.IsNullOrWhiteSpace

Answer 1

So now you want to replace all .string.IsNullOrWhiteSpace(str) with str.HasValue() ? Maybe you can use regex to achieve it.

Press Ctrl + F to open Find&Replace and check Use Regular Expressions

Next, input (.string?IsNullOrWhiteSpace\((.<name>".*")\)) into Find... ,

and ${name}.HasValue() into Replace... .

Then click Replace All .

For more info, you can refer to Use regular expressions in Visual Studio .

Not sure if this is what you want.
