Executes the strongly-typed query represented by a specified expression tree.
Assembly: System.Core (in System.Core.dll)

Parameters
- expression
- Type: System.Linq.Expressions::Expression
An expression tree that represents a LINQ query.
Return Value
Type: TResultThe 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.
