System.Linq.Expressions::Expression^

Type Parameters
- TResult
The type of the value that results from executing the query.
The Execute<TResult> 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<TResult>. They pass it a MethodCallExpression that represents a LINQ query.
