Replace method call to another

Question

I need to replace all the ocurances of obj.Method1() to obj.Method2() where obj is an instances of the same class. Does ReSharper or VS2010 allow this?

Answer 1

I'd cheat - Do a 3-point symbolic rename (Right-click->Rename on a method name)

• Method1 -> Temp
• Method2 -> Method1
• Temp -> Method2

None of this will change code functionality but will update all your code to use the correct name, except the methods themselves are now named incorrectly - simply rename the methods to by hand and voila - A little bit hacky but fast and effective.

This does rely on all method calls being in managed code (so that VS knows how/what to rename). If you have XML comments, C# rename handles this well but VB doesn't - I assume since you mention ReSharper, you're using C#?

This also assumes the method signatures are identical (if not, get ready for a lot of copy/pasting)

Answer 2

You could write a ReSharper Replace Pattern (ReSharper->Tools->Pattern Catalog, Add Pattern) like so:

where the type of expression obj needs to be changed to your class (that contains Method1).

Then press Save and thereafter press Search now to get all Method1() calls:

Then click Replace and all Method1 calls are type-safely replaced to Method2.

Answer 3

Make body of Method1 like this

public void Method1(...) { return Method2(...); }

And invoke refactoring "Inline method" on Method1.
