OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc Namespace > ServerDescriptor Class > Implicit Type Conversion Operator : Implicit Type Conversion(ServerDescriptor,String) Operator
Contains the descriptor string for the server.

The value represents a server descriptor string. 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. The server descriptor string is typically the ProgID (or {CLSID}) of the object, a string in the form "\\machineName\serverClass", or a URI of the object.

The value of this parameter can be null (Nothing in Visual Basic).

Converts a string containing server's descriptor string to a server descriptor.
