FromResourceDescriptor Method



OpcLabs.BaseLib Assembly > OpcLabs.BaseLib.Networking Namespace > ResourceAddress Class : FromResourceDescriptor Method
The resource descriptor to create the resource address from.

Because the OpcLabs.BaseLib.ResourceDescriptor has implicit conversions from System.String and System.Uri, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (usually representing the resource URL), or a System.Uri object, in place of this parameter, and the corresponding resource descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.BaseLib.ResourceDescriptor.FromString or OpcLabs.BaseLib.ResourceDescriptor.FromUri static method instead.

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

Creates a resource address from a resource descriptor.

Parameters

resourceDescriptor
The resource descriptor to create the resource address from.

Because the OpcLabs.BaseLib.ResourceDescriptor has implicit conversions from System.String and System.Uri, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (usually representing the resource URL), or a System.Uri object, in place of this parameter, and the corresponding resource descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.BaseLib.ResourceDescriptor.FromString or OpcLabs.BaseLib.ResourceDescriptor.FromUri static method instead.

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

Return Value

Returns the resource address object created from the resource descriptor.

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

Remarks

In languages that support implicit conversions (such as C# or VB.NET), in many cases you do not have call this method explicitly. When indicated, a call to an available equivalent implicit conversion operator will be created by the compiler automatically.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
