private bool RelinkDocuments()

{

try

{

SPSite site = SPContext .Current.Site;

SPWeb spWeb = site.OpenWeb();

SPList spList = spWeb.Lists[ new Guid ( "8E023C18-DAA3-4743-81B7-E034111544BC" )];

SPDocumentLibrary doclib = ( SPDocumentLibrary )spList;

string solutionUrl = SPHttpUtility .UrlPathEncode(spWeb.Url + "/" + doclib.DocumentTemplateUrl, true );

foreach ( SPListItem spItem in doclib.Items) //loop through the list items

{

SPFieldCollection spFields = spItem.Fields;

foreach ( SPField spField in spFields) //loop through fields resetting them

{

if (spField.Type != SPFieldType .Computed &&

spField.Type !=

spItem[spField.InternalName] = spItem[spField.InternalName];

}

catch ( Exception e)

SPContentType spContentType = spList.ContentTypes[( SPContentTypeId )spItem[ "ContentTypeId" ]];

if (spContentType != null ) //try to update the item with the content type's template url which is the updated one

{

if (spContentType.DocumentTemplate.StartsWith( "http://" ) ||

else if (spContentType.DocumentTemplate.StartsWith( "/" ))

{

spItem[

"TemplateUrl" ] = SPHttpUtility .UrlPathEncode(spWeb.Site.MakeFullUrl(spContentType.DocumentTemplate), true );

}

else

{

spItem[

"TemplateUrl" ] = SPHttpUtility .UrlPathEncode(spWeb.Url + '/' + spList.RootFolder + '/' + spContentType.DocumentTemplate, true );

}

else //no content type found so default template url to solution Url

{

spItem[

"TemplateUrl" ] = solutionUrl;

}

spItem.Update();
