   — or —

   If the Find and Replace window is already open, on the toolbar, choose Replace in Files.

Find what

To search for a new text string or expression, specify it in the box. To search for any of the 20 strings that you searched for most recently, open the list, and choose the string for which you want to search. Choose the adjacent Expression Builder button if you want to use one or more regular expressions in your search string. For more information, see Using Regular Expressions in Visual Studio.

Replace With

To replace instances of the string in the Find what box with another string, enter the replacement string in the Replace With box. To delete instances of the string in the Find what box, leave this field blank. Open the list to display the 20 strings for which you searched most recently. Choose the adjacent Expression Builder button if you want to use one or more regular expressions in your replacement string. For more information, see Using Regular Expressions in Visual Studio.

Look in

The option chosen from the Look in drop-down list determines whether Replace in Files searches only in currently active files or searches all files stored within certain folders. Select a search scope from the list, type a folder path, or click the Browse (...) button to display the Choose Search Folders dialog box and choose a set of folders to search. You can also type a path directly into the Look in box.

Find options

You can expand or collapse the Find options section. The following options can be selected or cleared:

Match case When selected, the Find Results windows will only display instances of the Find what string that are matched both by content and by case. For example, a search for "MyObject" with Match case selected will return "MyObject" but not "myobject" or "MYOBJECT."

Match whole word When selected, the Find Results windows will only display instances of the Find what string that are matched in complete words. For example, a search for "MyObject" will return "MyObject" but not "CMyObject" or "MyObjectC."

Use Regular Expressions When this check box is selected, you can use special notations to define patterns of text in the Find what or Replace with text boxes. For a list of these notations, see Using Regular Expressions in Visual Studio.

Look at these file types This list indicates the types of files to search through in the Look in directories. If this field is left blank, all of the files in the Look in directories will be searched.

Select any item in the list to enter a preconfigured search string that will find files of those particular types.

Result options

You can expand or collapse the Result options section. The following options can be selected or cleared:

Find Results 1 window When selected, the results of the current search will replace the content of the Find Results 1 window. This window opens automatically to display your search results. To open this window manually, select Other Windows from the View menu and choose Find Results 1.

Find Results 2 window When selected, the results of the current search will replace the content of the Find Results 2 window. This window opens automatically to display your search results. To open this window manually, select Other Windows from the View menu and choose Find Results 2.

Display file names only When this check box is selected, the Find Results windows list the full names and paths for all files that contain the search string. However, the results don't include the line of code where the string appears. This check box is available for Find in Files only.

Keep modified files open after Replace All When selected, leaves open all files in which replacements have been made, so you can undo or save the changes. Memory constraints might limit the number of files that can remain open after a replace operation.
