Queryable.Any<'TSource> Method (IQueryable<'TSource>, Expression<Func<'TSource, Boolean>>)
Determines whether any element of a sequence satisfies a condition.
Assembly: System.Core (in System.Core.dll)
static member Any<'TSource> : source:IQueryable<'TSource> * predicate:Expression<Func<'TSource, bool>> -> bool
A sequence whose elements to test for a condition.
Return ValueType: System.Boolean
true if any elements in the source sequence pass the test in the specified predicate; otherwise, false.
The type of the elements of source.
This method has at least one parameter of type Expression<'TDelegate> whose type argument is one of the Func<'T, 'TResult> types. For these parameters, you can pass in a lambda expression and it will be compiled to an Expression<'TDelegate>.
The MethodCallExpression that represents calling itself as a constructed generic method. It then passes the MethodCallExpression to the Execute<'TResult>(Expression) method of the IQueryProvider represented by the Provider property of the source parameter.method generates a
The query behavior that occurs as a result of executing an expression tree that represents callingdepends on the implementation of the type of the source parameter. The expected behavior is that it determines if any of the elements of source satisfy the condition specified by predicate.
