Sharepoint 2010. Api. How to get field history?

I have SPListItem and some text field. I need in code get all versions of this field EX:

1. version 1 "hello rorld"
2. version 2 "hello world"
3. version 3 "new application"

Any examples how to do that?

Try this:

foreach (SPListItemVersion version in item.Versions)
{
    Console.WriteLine(string.Format(
        "{0}. version {0} \"{1}\"", 
        version.VersionId, version["this field"]));
}
