I like to
pub byte[] Encrypt(object aValue)
where a is for argument I usually do this for class members
int iVariableName
string sVariableName
byte [] byData
sometimes ill append an 's' to arrays
string [] sNames
Common .net objects I like to turn to an acronym FolderBrowserDialog - fbd SaveFileDialog - sfd StringBuilder - sb Socket - soc or cli The result of a method is usually called result no matter what type.
