descriptorString
A URL string of the resource.

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

Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

A generic string is used instead of System.Uri, because in some cases, the value may not represent a real URI.

In languages that support implicit conversions (such as C# or VB.NET), in many cases you do not have call this constructor 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
