IQueryProvider.Execute Method
Definition
Overloads
Execute(Expression) |
Executes the query represented by a specified expression tree. |
Execute<TResult>(Expression) |
Executes the strongly-typed query represented by a specified expression tree. |
Execute(Expression)
Executes the query represented by a specified expression tree.
public:
System::Object ^ Execute(System::Linq::Expressions::Expression ^ expression);
public object Execute (System.Linq.Expressions.Expression expression);
public object? Execute (System.Linq.Expressions.Expression expression);
abstract member Execute : System.Linq.Expressions.Expression -> obj
Public Function Execute (expression As Expression) As Object
Parameters
- expression
- Expression
An expression tree that represents a LINQ query.
Returns
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 their associated IQueryable object is enumerated.
Applies to
Execute<TResult>(Expression)
Executes the strongly-typed query represented by a specified expression tree.
public:
generic <typename TResult>
TResult Execute(System::Linq::Expressions::Expression ^ expression);
public TResult Execute<TResult> (System.Linq.Expressions.Expression expression);
abstract member Execute : System.Linq.Expressions.Expression -> 'Result
Public 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
- Expression
An expression tree that represents a LINQ query.
Returns
- 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<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.
