You can also use MethodBase.GetCurrentMethod() which will inhibit the JIT compiler from inlining the method where it's used.
Update:
This method contains a special enumeration StackCrawlMark that from my understanding will specify to the JIT compiler that the current method should not be inlined.
This is my interpretation of the comment associated to that enumeration present in SSCLI. The comment follows:
// declaring a local var of this enum type and passing it by ref into a function
// that needs to do a stack crawl will both prevent inlining of the calle and
// pass an ESP point to stack crawl to
//
// Declaring these in EH clauses is illegal;
// they must declared in the main method body
