FromResource Method (_StreamLoader)



OpcLabs.BaseLib Assembly > OpcLabs.BaseLib.IO.ComTypes Namespace > _StreamLoader Interface : FromResource Method
The resource descriptor to load the value 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 cannot be null (Nothing in Visual Basic).

Loads a value from a resource, given a resource descriptor.

Parameters

resourceDescriptor
The resource descriptor to load the value from.
