ReadMultiple Method (EasyUAClient)

Reads multiple attributes, using array of argument objects as an input.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Function ReadMultiple( _
   ByVal readArgumentsArray() As UAReadArguments _
) As UAAttributeDataResult()

'Usage
 
Dim instance As EasyUAClient
Dim readArgumentsArray() As UAReadArguments
Dim value() As UAAttributeDataResult
 
value = instance.ReadMultiple(readArgumentsArray)

public UAAttributeDataResult[] ReadMultiple( 
   UAReadArguments[] readArgumentsArray
)

public:
array<UAAttributeDataResult^>^ ReadMultiple( 
   array<UAReadArguments^>^ readArgumentsArray
)

Parameters

readArgumentsArray: Array of OpcLabs.EasyOpc.UA.OperationModel.UAReadArguments. Array of argument objects specifying what to read from an OPC-UA server.

Return Value

Array of OpcLabs.EasyOpc.UA.OperationModel.UAAttributeDataResult. Returns an array of attribute data objects. Each object stores the value of an attribute, together with status code and timestamps. The indices of elements in the output array are the same as those in the input array, .

Exceptions

Exception	Description
System.ArgumentNullException	A `null` reference (`Nothing` in Visual Basic) is passed to a method that does not accept it as a valid argument.

Remarks

The size of the input array will become the size of the output array. The element positions (indices) in the output array are the same as in the input array.

This is a multiple-operation method. In a properly written program, it does not throw any exceptions. You should therefore not put try/catch statements or similar constructs around calls to this method. The only exceptions thrown by this method are for usage errors, i.e. when your code violates the usage contract of the method, such as passing in invalid arguments or calling the method when the state of the object does not allow it. Any operation-related errors (i.e. errors that depend on external conditions that your code cannot reliably check) are indicated in the result objects returned by the method. For more information, see Multiple-operation Methods and Do not catch any exceptions with asynchronous or multiple-operation methods.
