Question

In C# VS2008 how to replace intA = (int)obj.GetStr("xxx"); to intA = int.Parse(obj.GetStr("xxx"));

Answer 1

A:

Have you tried Search and Replace?

Search for 'intA = (int)obj.GetStr("', replace with 'intA = Convert.ToInt32(obj.GetStr("'.

And you'll still have to go line by line and add a trailing parenthesis ).

Yeah, but you could always use the crazy as all heck VS regex syntax and do an easy enough replace.

Quintin Robinson 2009-07-06 20:35:22

i can't simply do that because intA maybe intA, intB, intC....and obj maybe obj1, obj2, obj3....

CodeYun 2009-07-06 20:35:31

@CodeYun: add that to the question clarify it.

Adrian Godong 2009-07-06 20:38:19

@Quintin: VS regex really is "special", isn't it?

Answer 2

+1 A:

I don't like the new version either. When you know you have a string, int.Parse() or int.TryParse() is probably more appropriate.

Joel Coehoorn 2009-07-06 20:41:16

Yes, i totally agree with you. So how can I convert to int.Parse()

Answer 3

+2 A:

Try search and replace using the following regex:

EDIT: Replace the AAA, BBB, CCC values with the appropriate method names you want to match and replace. Be careful of using the :i (identifier) match predicate, as that would match any method call - which you probably don't want.

Find: (looks for any call on any expression to GetStr)

\(int\){.+}\.{(GetStr|AAA|BBB|CCC)}\({.*}\);

Replace With:

Convert.ToInt32(\1.\2(\3));

or (as others have mentioned) replace with:

Int.Parse(\1.\2(\3));

Thanks LBushkin.Actrually I want to replace all methods in the same pattern not only apply to GetStr, can you make some small change for that?

CodeYun 2009-07-06 20:45:58

Do you mean that you want to be able to convert types other than just int (like double, short, etc)? Or do you mean something else?

LBushkin 2009-07-06 20:48:41

Do the other methods all have a single string parameter, like GetStr?

Otis 2009-07-06 20:50:16

All methods just like this pattern:objQueueXML.AAA("//UserID");objQueueXML.BBB("//UserID");objQueueXML("//UserID");

CodeYun 2009-07-06 20:52:48

Or more generically, identifier.methodname("stringparameter"). I posted a variation on this answer that seems to match any method name.

Otis 2009-07-06 20:54:17

You may not want to make the RegEx to generic, otherwise you may find yourself replacing more than what you expect. I'll edit my post to include a version where the GetStr method is substituted with a list of method names you can define.

Answer 4

A:

This is a variation on what LBushkin suggested:

find: \(int\){:i\.:i\(:q\)}
replace: int.Parse(\1)
