My directory structure is as follows:
v1
file1.txt
file2.txt
common
common.txt
I need to create a C# function that can traverse this directory structure and generate JSON output. The expected JSON format is like this:
{
"v1": [
"file1.txt",
"file2.txt",
{
"common": [
"common.txt"
]
}
]
}
The keys represent folders and the values are arrays of files within those folders.
Currently, I have a function with the following implementation:
private static Dictionary<string, IEnumerable<string?>> Get(string baseDirectory, string version) =>
Directory.GetDirectories($"{baseDirectory}\\{version}")
.Select(x => new
{
Name = x,
Files = Directory.GetFiles(x).Select(Path.GetFileName),
})
.ToDictionary(o => Path.GetRelativePath(version, o.Name), o => o.Files);
This function only goes one level deep in the directory structure due to limitations of the Dictionary data type for expressing nested directories.
In TypeScript, I usually prototype types using union types. Here's an example type definition in TypeScript that describes nested directories using union types:
type DirectoryStructure<K extends string, V> = {
[P in K]: (V | DirectoryStructure<K, V>)[]
};
Unfortunately, C# does not have direct support for union types like TypeScript. I am seeking a solution in C# that can effectively describe nested directory structures and can be easily serialized to JSON. Any assistance on this matter would be greatly appreciated.
