A library for working with Windows 10, April 2018 Update's addition of per-directory case sensitivity.
**Important Note:** Although Windows now supports case-sensitive folders, most programs still do not, and will not behave properly when files with matching case-insensitive names exist. Only use `DirectoryCaseSensitivity.SetCaseSensitive()` when appropriate.
## Basic Example
Below is some of the basic functionality of the static class `DirectoryCaseSensitivity`.
```cs
using TriggersTools.IO.Windows;
// Check if we're in a high enough version of Windows. Calculated once per runtime
if (!DirectoryCaseSensitivity.IsSupported())
return;
const string dir = "Case Sensitive Folder";
const string file1 = "file1.txt";
const string FILE1 = "FILE1.txt";
// Create a case sensitive Folder
DirectoryCaseSensitivity.Create(dir, true);
// Outputs
// True
Console.WriteLine($"Is Case Sensitive: {DirectoryCaseSensitivity.IsCaseSensitive(dir)}");
// Create files with identical case-insensitive names
File.Create(file1).Close();
File.Create(FILE1).Close();
// Outputs:
// file1.txt
// FILE1.txt
foreach (string file in Directory.EnumerateFiles(dir))
Console.WriteLine(Path.GetFileName(file));
// Now disable case sensitivity
// IoException: 2 files have the same case-insensitive name
DirectoryCaseSensitivity.SetCaseSensitive(dir, false);
```
## Create/Inherit
`DirectoryCaseSensitivity` also comes with methods to create case sensitive directories, and/or inherit the case sensitivity of the parent directory. It's important to note that directories created through `Directory.CreateDirectory()` will always be case-insensitive when first created.
```cs
const string dir = "Case Sensitive Folder";
const string subdir1 = dir + @"\Directory.CreateDirectory";
const string subdir2 = dir + @"\DirectoryCaseSensitivity.Create";
const string subdir3 = dir + @"\DirectoryCaseSensitivity.CreateInherit";
// Create a case sensitive Folder
DirectoryCaseSensitivity.Create(dir, true);
Directory.CreateDirectory(subdir1);
DirectoryCaseSensitivity.Create(subdir2, true);
DirectoryCaseSensitivity.CreateInherit(subdir3);
// Output:
// Directory.CreateDirectory False
// DirectoryCaseSensitivity.Create True
// DirectoryCaseSensitivity.CreateInherit True
foreach (string subdir in Directory.EnumerateDirectories(dir)) {
bool enabled = DirectoryCaseSensitivity.IsCaseSensitive(subdir);
Console.WriteLine($"{Path.GetFileName(subdir),-40} {enabled}");
}
// Inherit will take an existing directory and set
// its case sensitivity to that of its parent.
// It also returns the inherited sensitivity.
// Outputs:
// Directory.CreateDirectory inherit: True
Console.WriteLine($"{subdir1} inherit: {DirectoryCaseSensitivity.Inherit(sibdir1)}");
```
## DirectoryInfo Extensions
`DirectoryInfo` gets extension methods for `IsCaseSensitive()` and `SetCaseSensitive()`.
```cs
const string dir = "Case Sensitive Folder";
Directory.CreateDirectory(dir);
DirectoryInfo dirInfo = new DirectoryInfo(dir);
// Outputs
// False
Console.WriteLine($"Is Case Sensitive: {dirInfo.IsCaseSensitive()}");
dirInfo.SetCaseSensitive(true);
// Outputs
// True
Console.WriteLine($"Is Case Sensitive: {dirInfo.IsCaseSensitive()}");
```
