static member Invoke : System.Data.Metadata.Edm.EdmFunction * System.Data.Common.CommandTrees.DbExpression[] -> System.Data.Common.CommandTrees.DbFunctionExpression

<Extension()>
Public Function Invoke (function As EdmFunction, ParamArray arguments As DbExpression()) As DbFunctionExpression

Parameters

function

EdmFunction

Metadata for the function to invoke.

arguments

DbExpression[]

Expressions that provide the arguments to the function.

Returns

DbFunctionExpression

A new DbFunctionExpression representing the function invocation.

Exceptions

ArgumentNullException

function is null, or arguments is null or contains null.

ArgumentException

The count of arguments does not equal the number of parameters declared by function, or arguments contains an expression that has a result type that is not equal or promotable to the corresponding function parameter type.

Invoke(EdmFunction, IEnumerable<DbExpression>)

Creates a new DbFunctionExpression representing the invocation of the specified function with the given arguments.

public:
[System::Runtime::CompilerServices::Extension]
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ Invoke(System::Data::Metadata::Edm::EdmFunction ^ function, System::Collections::Generic::IEnumerable<System::Data::Common::CommandTrees::DbExpression ^> ^ arguments);

public static System.Data.Common.CommandTrees.DbFunctionExpression Invoke (this System.Data.Metadata.Edm.EdmFunction function, System.Collections.Generic.IEnumerable<System.Data.Common.CommandTrees.DbExpression> arguments);

static member Invoke : System.Data.Metadata.Edm.EdmFunction * seq<System.Data.Common.CommandTrees.DbExpression> -> System.Data.Common.CommandTrees.DbFunctionExpression

<Extension()>
Public Function Invoke (function As EdmFunction, arguments As IEnumerable(Of DbExpression)) As DbFunctionExpression

Parameters

function

EdmFunction

Metadata for the function to invoke.

arguments

IEnumerable<DbExpression>

A list of expressions that provide the arguments to the function.

Returns

DbFunctionExpression

A new DbFunctionExpression representing the function invocation.

Exceptions

ArgumentNullException

function is null, or arguments is null or contains null.

ArgumentException

The count of arguments does not equal the number of parameters declared by function, or arguments contains an expression that has a result type that is not equal or promotable to the corresponding function parameter type.

Invoke(DbLambda, IEnumerable<DbExpression>)

Creates a new DbLambdaExpression representing the application of the specified Lambda function to the given arguments.

public:
[System::Runtime::CompilerServices::Extension]
 static System::Data::Common::CommandTrees::DbLambdaExpression ^ Invoke(System::Data::Common::CommandTrees::DbLambda ^ lambda, System::Collections::Generic::IEnumerable<System::Data::Common::CommandTrees::DbExpression ^> ^ arguments);

public static System.Data.Common.CommandTrees.DbLambdaExpression Invoke (this System.Data.Common.CommandTrees.DbLambda lambda, System.Collections.Generic.IEnumerable<System.Data.Common.CommandTrees.DbExpression> arguments);

static member Invoke : System.Data.Common.CommandTrees.DbLambda * seq<System.Data.Common.CommandTrees.DbExpression> -> System.Data.Common.CommandTrees.DbLambdaExpression

<Extension()>
Public Function Invoke (lambda As DbLambda, arguments As IEnumerable(Of DbExpression)) As DbLambdaExpression

Parameters

lambda

DbLambda

A DbLambda instance representing the Lambda function to apply.

arguments

IEnumerable<DbExpression>

A list of expressions that provide the arguments.

Returns

DbLambdaExpression

A new DbLambdaExpression representing the Lambda function application.

Exceptions

ArgumentNullException

lambda or arguments is null.

ArgumentException

The count of arguments does not equal the number of variables declared by lambda, or arguments contains an expression that has a result type that is not equal or promotable to the corresponding variable type.

Invoke(DbLambda, DbExpression[])

Creates a new DbLambdaExpression representing the application of the specified Lambda function to the given arguments.

public:
