An error occurred while undoing the file checkout.

This method reverts an existing online or offline checkout for the current file.

The following code example undoes the checkout for files in the Shared Documents document library of a subsite if the specified user is the one who checked them out.

SPSite oSiteCollection = SPContext.Current.Site;
SPWeb oWebsite = oSiteCollection.AllWebs["Site_Name/Subsite_Name"]
SPFolder oFolder = oWebsite.Folders["Shared Documents"];
SPFileCollection collFiles = oFolder.Files;

for (int intIndex=0; intIndex<collFiles.Count; intIndex++)
    if (collFiles[intIndex].CheckedOutBy.LoginName == "Domain_Name\\User")
