250-256: LGTM! Consider enhancing the documentation slightly.The addition of the
CreateTargetDirectoriesproperty is well-implemented and aligns with the PR objectives. The default value offalseensures backward compatibility.Consider enhancing the XML documentation slightly to clarify the behavior when set to
false:/// <summary> /// If set, will create the target directory if it does not exist, -/// as well as any sub directories. +/// as well as any sub directories. If false, throws an exception +/// when the target directory doesn't exist. /// </summary>
283-289: LGTM! Consider enhancing the documentation slightly.The addition of the
CreateTargetDirectoriesproperty toWriteBytesOptionis consistent with the changes made toWriteOption, which is excellent for maintaining a uniform API.As with the
WriteOptionclass, consider enhancing the XML documentation slightly:/// <summary> /// If set, will create the target directory if it does not exist, -/// as well as any sub directories. +/// as well as any sub directories.

290-297: Approve changes with suggestion for error handlingThe implementation of the
CreateTargetDirectoriesoption is correct and aligns with the PR objectives. It successfully creates the target directory if it doesn't exist before writing the file.Consider adding error handling for the directory creation process. This will provide more robust behavior and better error reporting. Here's a suggested implementation:
if(options.CreateTargetDirectories) { var directoryPath = Path.GetDirectoryName(input.Path); if(!Directory.Exists(directoryPath)) { - Directory.CreateDirectory(directoryPath); + try + { + Directory.CreateDirectory(directoryPath); + } + catch (Exception ex) + { + throw new IOException($"Failed to create directory '{directoryPath}': {ex.Message}", ex); + } } }This change will catch any exceptions during directory creation and throw a more informative
IOException, which is consistent with other IO-related exceptions in the .NET framework.
310-317: Approve changes with suggestion for error handlingThe implementation of the
CreateTargetDirectoriesoption inExecuteWriteBytesis correct and consistent with the changes inExecuteWrite. It successfully creates the target directory if it doesn't exist before writing the file.As with the
ExecuteWritemethod, consider adding error handling for the directory creation process. Here's a suggested implementation:if (options.CreateTargetDirectories) { var directoryPath = Path.GetDirectoryName(input.Path); if (!Directory.Exists(directoryPath)) { - Directory.CreateDirectory(directoryPath); + try + { + Directory.CreateDirectory(directoryPath); + } + catch (Exception ex) + { + throw new IOException($"Failed to create directory '{directoryPath}': {ex.Message}", ex); + } } }This change will provide more robust behavior and better error reporting, consistent with the suggestion for the
ExecuteWritemethod.

290-317: Summary of changes and minor improvement suggestionThe implementation of the
CreateTargetDirectoriesoption in bothExecuteWriteandExecuteWriteBytesmethods is consistent and fulfills the PR objective. The code is well-placed and logically sound.To further improve the implementation, consider extracting the directory creation logic into a separate private method. This would reduce code duplication and centralize the error handling. Here's a suggested implementation:
private static void EnsureDirectoryExists(string filePath) { var directoryPath = Path.GetDirectoryName(filePath); if (!Directory.Exists(directoryPath)) { try { Directory.CreateDirectory(directoryPath); } catch (Exception ex) { throw new IOException($"Failed to create directory '{directoryPath}': {ex.Message}", ex); } } }Then, in both
ExecuteWriteandExecuteWriteBytesmethods, you can replace the existing block with:if (options.CreateTargetDirectories) { EnsureDirectoryExists(input.Path); }This change would improve code maintainability and ensure consistent behavior across both methods.
Frends.File.Tests/UnitTest.cs (5)
364-380: LGTM! Consider adding directory existence check.The test effectively verifies the ability to write a file to a new subdirectory when
CreateTargetDirectoriesis set to true.Consider adding an assertion to verify that the directory was actually created:
Assert.True(Directory.Exists(Path.GetDirectoryName(result.Path)));
382-396: LGTM! Consider verifying exception message.The test correctly verifies that a
DirectoryNotFoundExceptionis thrown when attempting to write to a non-existent directory without theCreateTargetDirectoriesoption.Consider adding a check for the exception message to ensure it provides the expected information:
Assert.Contains("Could not find a part of the path", result.Message);
466-484: LGTM! Consider adding directory existence check.The test effectively verifies the ability to write a byte array to a file in a new subdirectory when
CreateTargetDirectoriesis set to true.Similar to the
WriteFileCreateDirectorytest, consider adding an assertion to verify that the directory was actually created:Assert.True(Directory.Exists(Path.GetDirectoryName(result.Path)));
485-500: LGTM! Consider verifying exception message.The test correctly verifies that a
DirectoryNotFoundExceptionis thrown when attempting to write bytes to a non-existent directory without theCreateTargetDirectoriesoption.Similar to the
WriteFileCreateDirectoryThrowtest, consider adding a check for the exception message:Assert.Contains("Could not find a part of the path", result.Message);
Line range hint
364-500: Overall, excellent test coverage for the new functionality.The new test methods effectively cover the scenarios for writing files and bytes with the option to create target directories. They test both the successful creation of directories and the appropriate exception throwing when the option is disabled.
To further enhance the test suite:
- Consider adding edge cases, such as nested directories with multiple levels.
- Test with various file types and sizes to ensure robustness.
- Add tests for concurrent write operations to the same directory to verify thread safety.

250-256: Overall changes are well-implemented and consistent.The addition of the
CreateTargetDirectoriesproperty to bothWriteOptionandWriteBytesOptionclasses is consistent and aligns well with the PR objectives. These changes enhance the functionality of write operations without affecting other file operations, maintaining backward compatibility.To ensure that these changes are properly utilized, please verify that the corresponding write methods (
WriteandWriteBytes) have been updated to use this new property. You can use the following script to check for updates in the implementation files:Also applies to: 283-289

Tasks Write and WriteBytes now have the option to create target directories if they do not exist removing the need to use "Create Directory".
