How to use FileTransferManager C# Library

 Tutorial: How to use martinchrzan's FileTransferManager C# Library:

Today i want to talk a little bit about the FileTransferManager Library from martinchranz.

As I could not find any docs on Github I decided to write a post covering the usage of the Library in one example.

Tutorial

cancelToken

Requirements:

• Visual Studio 2022 Community/Enterprise/Professional
• Browser
• Some Knowledge of C#
• .Net development enabled in Visual Studio
• The FileTransferManager Library from martinchranz installed via NuGet

Tutorial:

First import the library to your project like this:

using CopyManager = IOExtensions.FileTransferManager;

If you want you can add a cancelToken to it, then please import System.Threading too:

using System.Threading;

Then you are able to start! In the following example we are going to copy a folder with the "CopyWithProgressAsync" function:

It uses the following options:

CopyManager.CopyWithProgressAsync(sourceDir, destinationDir, ProgressHandlefunction, boolifcontinueonfailure, cancelToken);

As it is an Async function you need to invoke the HandleProgressfunction as the following:

First create a function which is called:

        private void HandleProgress(IOExtensions.TransferProgress progress)

        {

            if (InvokeRequired)

            {

                Invoke(new HandleProgressDelegate(HandleProgressShower), progress);

                return;

            }

            

        }

Then crete a delegate function:

        private delegate void HandleProgressDelegate(IOExtensions.TransferProgress progress);

And the final function which gives the progress to the ui:

        private void HandleProgressShower(IOExtensions.TransferProgress progress)

        {

            progressbar.Value = (int)progress.Percentage;

        }

How to use the cancelToken:

To use a cancel Token you need to create a global cancelToken:

CancellationTokenSource cancelSource;

cancelSource = new CancellationTokenSource();

If you want to cancel the copy just tell the cancelToken:

cancelSource.Cancel();

I hope tht this post helped you!
