// Import the necessary namespaces for working with Azure File Storage
using Azure.Storage.Files.Shares;
using Azure.Storage.Files.Shares.Models;
using System.IO;

// Specify the connection string for your Azure File Storage account
string connectionString = "your_connection_string";

// Specify the name of the file share where you want to upload the file
string shareName = "your_share_name";

// Specify the desired name for the file you want to upload
string fileName = "your_file_name";

// Replace this with your actual data retrieval logic or provide your own dummy data
string dummyText = "This is a sample file content.";
byte[] dummyData = Encoding.UTF8.GetBytes(dummyText);

// Replace this with your actual stream retrieval logic
// For demonstration purposes, we'll create a MemoryStream with dummy data
MemoryStream stream = new MemoryStream(dummyData);


// Get the stream that contains the data you want to upload
// Stream stream = GetYourFileStream(); // Replace with your own stream if you don't want to use the above code.

// Create a client to interact with the file in the Azure File Storage
ShareFileClient fileClient = new ShareFileClient(connectionString, shareName, fileName);

// Specify the upload options, including transfer options
ShareFileUploadOptions uploadOptions = new ShareFileUploadOptions
{
    TransferOptions = new StorageTransferOptions
    {
        // Specify the initial and maximum transfer size for the upload
        InitialTransferSize = 1024 * 1024 * 4,
        MaximumTransferSize = 1024 * 1024 * 4
    }
};

// Create the file on the Azure File Storage with the specified size
await fileClient.CreateAsync(stream.Length);

// Upload the stream to the file in the Azure File Storage, using the specified upload options
await fileClient.UploadAsync(stream, uploadOptions);
