Is there a Windows utility that will let me do multiple programmatic find/replaces on text that I cut & paste into it?

I've inherited some C# code that contains about a thousand lines of source that I need to modify, transforming it from this:

newDataRow["to_dir"] = comboBox108.Text;

To this:

assetAttributes.Add("to_dir", comboBox108.Text);

The lines occur in various places throughout the application in groups of 40 or 50. Modifying each line by hand in Visual Studio 2008 can be done but it's labor intensive and prone to errors.

Is开发者_运维百科 there a Windows utility out there that will let me cut and paste groups of code into it and then run some sort of reg-ex expression to transform the individual lines one-by-one? I'd also be willing to use some sort of VS 2008 add-in that performed the same set of reg-ex operations against a selection of code.

Thanks in advance.

While not a great experience, you can use the VS2008 built-in search & replace to do this.

Note that it has its own regex syntax. To do this, go to Edit | Find & Replace | Replace in files. Then expand "Find Options" and select use regular expressions.

Try this - test and fix... For your search term, use
newDataRow\[{"[."]*"}\] = {[^;]*} and replace with assetAttributes.Add\("\1", \2\);

The \1 and \2 identifiers are the first and second groups (surrounded with {}) that were found. hit the arrows next to the search terms for a menu, select the botom option to go to help.

If you simply want a text editor that can do this, you might want to try PSPad - the find/replace allows for regular expression useage.

In Visual Studio, Find and Replace allows you to replace using regular expressions. In the Find and Replace dialog, under Find options, there is a 'Use' checkbox with Regular expressions in it. Use the arrows next to 'Find what' and 'Replace with' to learn about Visual Studio's slightly different syntax.

Using the regular expression search and replace, you can search for:

newDataRow\["([a-zA-Z_]+)"\] = comboBox([0-9]+).Text;

and replace with

assetAttributes.Add("\1", comboBox\2.Text);

which should do the trick :o)

Windows Grep is great, and should do exactly what you want, and more:

My choice of tool in this matter would probably be Notepad++ (Search/Find in Finds - does replace too). Supports RegExps.
