Public Function All (source As DbExpression, predicate As Func(Of DbExpression, DbExpression)) As DbQuantifierExpressionParameters
- source
- DbExpression
An expression that specifies the input set.
- predicate
- Func<DbExpression,DbExpression>
A method representing a predicate to evaluate for each member of the input set. This method must produce an expression with a Boolean result type that provides the predicate logic.
Returns
A new DbQuantifierExpression that represents the All operation.
Exceptions
source or predicate is null.
-or-
The expression produced by predicate is null.
source does not have a collection result type.
-or-
The expression produced by predicate does not have a Boolean result type.
