    Expression expression

Type Parameters

  • TResult
    The type of the value that results from executing the query.


Return Value

Type: TResult
The value that results from executing the specified query.


The Execute method executes queries that return a single value (instead of an enumerable sequence of values). Expression trees that represent queries that return enumerable results are executed when the IQueryable<T> object that contains the expression tree is enumerated.

The Queryable standard query operator methods that return singleton results call Execute. They pass it a MethodCallExpression that represents a LINQ query.
