Best way to get whole number part of a Decimal number

What is the best way to return the whole number part of a decimal (in c#)? (This has to work for very large numbers that may not fit into an int).

GetIntPart(343564564.4342) >> 343564564
GetIntPart(-323489.32) >> -323489
GetIntPart(324) >> 324

The purpose of this is: I am inserting into a decimal (30,4) field in the db, and want to ensure that I do not try to insert a number than is too long for the field. Determining the length of the whole number part of the decimal is part of this operation.

See the top answer above. This doesn't work because (int)Decimal.MaxValue will overflow.
