SPC055201: Consider using SPContentTypeCollection.BestMatch(SPContentTypeId) to retrieve a Content Type

Use SPContentTypeCollection.BestMatch(string) to retrieve a Content Type from a SPContentTypeCollection.

CheckId SPC055201
TypeName ConsiderBestMatchForContentTypesRetrieval
Severity CriticalWarning
Type Assembly
Resolution

Consider using SPContentTypeCollection.BestMatch() instead of using the indexer. See sample below:
Bad Practice

// get the ContentType via index which failes if the exact ContentType is not there
SPContentTypeId ctypeId = new SPContentTypeId("0x010008F15D6B2D0A466BA95AA5D91E21416E");
SPContentType cType = web.ContentTypes[ctypeId];
...

Good Practice
// get the nearest match to the specified ContentType ID
SPContentTypeId ctypeId = new SPContentTypeId("0x010008F15D6B2D0A466BA95AA5D91E21416E");
SPContentTypeId matchId = web.ContentTypes.BestMatch(id);
SPContentType cType = web.ContentTypes[matchId];
...
