Implicit Type Conversion(UAQualifiedName,String) Operator

Converts a System.String to a qualified name.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<NotNullAttribute()>
Overloads Public Operator Widening CType( _
   ByVal expandedText As String _
) As UAQualifiedName

'Usage

[NotNull()]
public UAQualifiedName operator implicit( 
   string expandedText
)

[NotNull()]
public:
operator UAQualifiedName^ ( 
   String^ expandedText
)

Parameters

expandedText: The string to be converted.
The value of this parameter can be null (Nothing in Visual Basic).

Return Value

For a non-null input, returns the qualified name with the given expanded text. Returns a qualified name with an empty expanded text if the input is null.

Because the UAQualifiedName has an implicit conversion to System.String, and it converts to the expanded text of the qualified name (ExpandedText), in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UAQualifiedName in any place where expanded text of a qualified name (a string) is expected as input, and the corresponding expanded text will be taken automatically from the qualified name.

Also, because the OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElement has an implicit conversion from UAQualifiedName, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UAQualifiedName (containing a target qualified name, which becomes the "any hierarchical" forward reference) in any place where OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElement is expected as input, and the corresponding OPC UA browse path element will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElement.FromUAQualifiedName static method instead.

Also, because the OpcLabs.EasyOpc.UA.UAReadParameters has an implicit conversions from UAQualifiedName, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply the returned UAQualifiedName (representing the name of the encoding to be used) in any place where OpcLabs.EasyOpc.UA.UAReadParameters is expected as input, and the corresponding OPC UA read parameters will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromDouble or FromUAQualifiedName static method instead.

This method never returns null (Nothing in Visual Basic).

Remarks

For non-null inputs, this operator is equivalent to UAQualifiedName Constructor(String).

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
