When would you say a function() name is too long?

Question

As I’m learning more and more each day, one common trend I am noticing is that some of my function names are long.
I.E - GetUserInfoByComboBox();
As a function name it seems straight forward, but would you consider this too long? I went back and changed it to just
GetUser() which works fine in this case, but sometimes in other situations I feel like it isn’t descriptive enough and I’m having to go double check comments.
What do you guys think? Or is this an example of bad software design?

Answer 1

I think that is better to use longer names if you better understanding then and that is most important...

Answer 2

you usually name a function what it does so its simple for readers to understand it better but you dont want to make it so long its a annoying to type out

Answer 3

I try to keep variable names and method names as short as possible and as descriptive as possible.

I do not use abbrevations
a variable name should only contain a noun
a method name should have verb and a noun

So a variable can be "User"
A method name can be "GetUser"
So a variable can be "UserInfo"
A method name can be "GetUserInfo"

I try to avoid GetUserInfoByComboBox, because I do not want my method to be depend on User interface elements.
