The ReadAllBytesAsync method in the BaseFileSystem class is an asynchronous operation that reads all bytes from a specified file path and returns them as a byte array. This method is useful for non-blocking file read operations, allowing other tasks to run concurrently while the file is being read.
To use the ReadAllBytesAsync method, you need to provide the file path as a string parameter. The method will return a Task<byte[]>, which you can await to get the byte array once the read operation is complete.
Ensure that the file path is valid and accessible, and handle any exceptions that may occur during the file read operation, such as FileNotFoundException or UnauthorizedAccessException.
// Example usage of ReadAllBytesAsync
public async Task<byte[]> GetFileBytesAsync(string filePath)
{
BaseFileSystem fileSystem = new BaseFileSystem();
try
{
byte[] fileBytes = await fileSystem.ReadAllBytesAsync(filePath);
return fileBytes;
}
catch (Exception ex)
{
// Handle exceptions such as file not found or access denied
Console.WriteLine($"Error reading file: {ex.Message}");
return null;
}
}
