'Usage

Dim instance As IQueryProvider
Dim expression As Expression
Dim returnValue As TResult

returnValue = instance.Execute(expression)

'Declaration

Function Execute(Of TResult) ( _
    expression As Expression _
) As TResult

Type Parameters

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

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.

Remarks

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.
