Parameters

client

The client object that will perform the operation.

This is typically the EasyDAClient object.

The value of this parameter cannot be null (Nothing in Visual Basic).

machineName

Name of the machine (empty string for local computer).

The value represents a UNC or DNS computer name. Any string can be passed to this parameter (i.e. will not cause System.ArgumentException), but not all values make sense and will work when an operation using them is attempted. IPv6 addresses are normally enclosed between '[' and ']'.

The value of this parameter cannot be null (Nothing in Visual Basic).

serverClass

Contains ProgID of the OPC server to browse.

The value of this parameter cannot be null (Nothing in Visual Basic).

parentItemId

ID of the parent branch to be browsed (empty string for root)

The value of this parameter cannot be null (Nothing in Visual Basic).

elementNameFilter

A wildcard string to filter the returned element names (empty string for no filtering)

The value of this parameter cannot be null (Nothing in Visual Basic).

vendorFilter

A server specific filter string (empty string for no filtering)

The value of this parameter cannot be null (Nothing in Visual Basic).

Return Value

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
