A requirement I came across recently was to write a tool to set a site’s locale from US to UK using the object model.  Because I potentially needed to do this for hundreds of sites I opted to write a small command line tool that can be scripted to help with the task.

Below is an overview of how to use the SPLocale class to set the Locale of a site.  I have also provided download links for the compiled command line tool and its source code for you to take a look at.

First thing we need to do is grab an instance of the site:

SPSite site = new SPSite(“localhost”);

Next thing we do is get a collection of all the web sites under your site:

SPWebCollection webCollection = site.AllWebs;

We can now interate over this collection and set the Locale property to your new locale which will be an instance of the CultureInfo class. We create a new instance of the CultureInfo class by passing the new Locale’s LCID value to it’s constructor.

foreach (SPWeb web in webCollection)

{

      web.Locale = new System.Globalization.CultureInfo(2057);

      web.Update();

}

Thats basically all there is to it.
