DbExpressionBuilder.Lambda Method

Definition

Namespace:

System.Data.Common.CommandTrees.ExpressionBuilder

Assembly:

System.Data.Entity.dll

Creates a DbLambda with the specified inline Lambda function implementation and formal parameters.

Overloads

Lambda(DbExpression, IEnumerable<DbVariableReferenceExpression>)	Creates a DbLambda with the specified inline Lambda function implementation and formal parameters.
Lambda(DbExpression, DbVariableReferenceExpression[])	Creates a DbLambda with the specified inline Lambda function implementation and formal parameters.

Lambda(DbExpression, IEnumerable<DbVariableReferenceExpression>)

Creates a DbLambda with the specified inline Lambda function implementation and formal parameters.

public:
 static System::Data::Common::CommandTrees::DbLambda ^ Lambda(System::Data::Common::CommandTrees::DbExpression ^ body, System::Collections::Generic::IEnumerable<System::Data::Common::CommandTrees::DbVariableReferenceExpression ^> ^ variables);

public static System.Data.Common.CommandTrees.DbLambda Lambda (System.Data.Common.CommandTrees.DbExpression body, System.Collections.Generic.IEnumerable<System.Data.Common.CommandTrees.DbVariableReferenceExpression> variables);

static member Lambda : System.Data.Common.CommandTrees.DbExpression * seq<System.Data.Common.CommandTrees.DbVariableReferenceExpression> -> System.Data.Common.CommandTrees.DbLambda

Public Function Lambda (body As DbExpression, variables As IEnumerable(Of DbVariableReferenceExpression)) As DbLambda

Parameters

body

DbExpression

An expression that defines the logic of the Lambda function.

variables

IEnumerable<DbVariableReferenceExpression>

A DbVariableReferenceExpression collection that represents the formal parameters to the Lambda function. These variables are valid for use in the body expression.

Returns

DbLambda

A new DbLambda that describes an inline Lambda function with the specified body and formal parameters.

Exceptions

ArgumentNullException

variables is null or contains null, or body is null.

ArgumentException

variables contains more than one element with the same variable name.

Lambda(DbExpression, DbVariableReferenceExpression[])

Creates a DbLambda with the specified inline Lambda function implementation and formal parameters.

public:
 static System::Data::Common::CommandTrees::DbLambda ^ Lambda(System::Data::Common::CommandTrees::DbExpression ^ body, ... cli::array <System::Data::Common::CommandTrees::DbVariableReferenceExpression ^> ^ variables);

public static System.Data.Common.CommandTrees.DbLambda Lambda (System.Data.Common.CommandTrees.DbExpression body, params System.Data.Common.CommandTrees.DbVariableReferenceExpression[] variables);

static member Lambda : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbVariableReferenceExpression[] -> System.Data.Common.CommandTrees.DbLambda

Public Function Lambda (body As DbExpression, ParamArray variables As DbVariableReferenceExpression()) As DbLambda

Parameters

body

DbExpression

An expression that defines the logic of the Lambda function.

variables

DbVariableReferenceExpression[]

A DbVariableReferenceExpression collection that represents the formal parameters to the Lambda function. These variables are valid for use in the body expression.

Returns

DbLambda

A new DbLambda that describes an inline Lambda function with the specified body and formal parameters.

Exceptions

ArgumentNullException

variables is null or contains null, or body is null.

ArgumentException

variables contains more than one element with the same variable name.
