DaoCriteria ( ) : System

Constructs a blank criteria, which will return all records unless you customize it. All expressions added to it will be ANDed together.
DaoCriteria ( BooleanOperator howToAddExpressions ) : System

Constructs a blank criteria, which will return all records unless you customize it.
DaoCriteria ( IExpression firstExpr ) : System

Constructs a criteria with one expression. May be handy for cases where you only need one expression.
DaoCriteria ( IExpression firstExpr, BooleanOperator howToAddExpressions ) : System

Constructs a criteria with one expression.
