FromDirectoryDataProvider

The FromDirectoryDataProvider provides file data from a file in a given directory.

Properties

• Directory: The directory from which the data will be fetched.
• RelativePath: Relative path to the directory.

Methods

GetFileData

Retrieves file data from the directory based on the given start index and length.

public IFileData GetFileData(ulong start, ulong length)

Usage

The FromDirectoryDataProvider is used to fetch file data from a directory. The directory and relative path are stored separately to save memory. When GetFileData is called, the directory and relative path are combined temporarily to fetch the data. Here's an example:

var dataProvider = new FromDirectoryDataProvider
{
    Directory = "/path/to/directory",
    RelativePath = "relative/path/to/file"
};

using var fileData = dataProvider.GetFileData(0, 1024);

// Use fileData...

In this example, a FromDirectoryDataProvider is created and used to fetch the first 1024 bytes of a file located in the directory /path/to/directory and the relative path relative/path/to/file. The resulting IFileData object can then be used as needed.
