DbExpressionBuilder.Any Method

Definition

Namespace:

System.Data.Entity.Core.Common.CommandTrees.ExpressionBuilder

Assembly:

EntityFramework.dll

Overloads

Any(DbExpression)	Creates a new DbExpression that determines whether the specified set argument is non-empty.
Any(DbExpression, Func<DbExpression,DbExpression>)	Creates a new DbQuantifierExpression that determines whether the given predicate holds for any element of the input set.
Any(DbExpressionBinding, DbExpression)	Creates a new DbQuantifierExpression that determines whether the given predicate holds for any element of the input set.

Any(DbExpression)

Creates a new DbExpression that determines whether the specified set argument is non-empty.

public static System.Data.Entity.Core.Common.CommandTrees.DbExpression Any (this System.Data.Entity.Core.Common.CommandTrees.DbExpression source);

static member Any : System.Data.Entity.Core.Common.CommandTrees.DbExpression -> System.Data.Entity.Core.Common.CommandTrees.DbExpression

<Extension()>
Public Function Any (source As DbExpression) As DbExpression

Parameters

source

DbExpression

An expression that specifies the input set.

Returns

DbExpression

A new DbNotExpression applied to a new DbIsEmptyExpression with the specified argument.

Exceptions

ArgumentNullException

source is null.

ArgumentException

source does not have a collection result type.

Any(DbExpression, Func<DbExpression,DbExpression>)

Creates a new DbQuantifierExpression that determines whether the given predicate holds for any element of the input set.

public static System.Data.Entity.Core.Common.CommandTrees.DbQuantifierExpression Any (this System.Data.Entity.Core.Common.CommandTrees.DbExpression source, Func<System.Data.Entity.Core.Common.CommandTrees.DbExpression,System.Data.Entity.Core.Common.CommandTrees.DbExpression> predicate);

static member Any : System.Data.Entity.Core.Common.CommandTrees.DbExpression * Func<System.Data.Entity.Core.Common.CommandTrees.DbExpression, System.Data.Entity.Core.Common.CommandTrees.DbExpression> -> System.Data.Entity.Core.Common.CommandTrees.DbQuantifierExpression

<Extension()>
Public Function Any (source As DbExpression, predicate As Func(Of DbExpression, DbExpression)) As DbQuantifierExpression

Parameters

source

DbExpression

An expression that specifies the input set.

predicate

Func<DbExpression,DbExpression>

A method representing the predicate to evaluate for each member of the input set. This method must produce an expression with a Boolean result type that provides the predicate logic.

Returns

DbQuantifierExpression

A new DbQuantifierExpression that represents the Any operation.

Exceptions

ArgumentNullException

The expression produced by predicate is null.

ArgumentException

The expression produced by predicate does not have a Boolean result type.

Any(DbExpressionBinding, DbExpression)

Creates a new DbQuantifierExpression that determines whether the given predicate holds for any element of the input set.

public static System.Data.Entity.Core.Common.CommandTrees.DbQuantifierExpression Any (this System.Data.Entity.Core.Common.CommandTrees.DbExpressionBinding input, System.Data.Entity.Core.Common.CommandTrees.DbExpression predicate);

static member Any : System.Data.Entity.Core.Common.CommandTrees.DbExpressionBinding * System.Data.Entity.Core.Common.CommandTrees.DbExpression -> System.Data.Entity.Core.Common.CommandTrees.DbQuantifierExpression

<Extension()>
Public Function Any (input As DbExpressionBinding, predicate As DbExpression) As DbQuantifierExpression

Parameters

input

DbExpressionBinding

An expression binding that specifies the input set.

predicate

DbExpression

An expression representing a predicate to evaluate for each member of the input set.

Returns

DbQuantifierExpression

A new DbQuantifierExpression that represents the Any operation.

Exceptions

ArgumentNullException

input or predicate is null.

ArgumentException

The expression produced by predicate does not have a Boolean result type.
