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(Of 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.
