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.

Part of a file or directory cannot be found.

This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately.

An I/O error has occurred.

This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately.

An invoked method is not supported at all, or is not supported with the parameters used to create the object.

A security error was detected.

This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately.

The operating system has denied access because of an I/O error or a specific type of security error.

This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately.

Remarks

For Microsoft.Extensions.FileProviders.IDirectoryContents, IDirectory2, IDirectoryContents2, IWritableDirectory and IWritableDirectoryContents, relative paths are based on the directory itself; absolute paths are based on the root directory of the file provider. Notice the difference from Microsoft.Extensions.FileProviders.IFileInfo, IFileInfo2 and IWritableFileInfo, where relative paths are based on the directory where the file is located.

Requirements

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