IQueryProvider.Execute<TResult> Method (Expression)

Executes the strongly-typed query represented by a specified expression tree.

	Expression expression
)

Type Parameters

Parameters

expression
Type: System.Linq.Expressions.Expression
An expression tree that represents a LINQ 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.
