Lock and unlock files

The following example shows you how to lock a file, change it while it is locked, refresh the lock and unlock it. The client submits the lock token automatically when it changes the locked file.

C# example

using System;
using System.Net;
using System.Threading.Tasks;
using Independentsoft.Webdav;

namespace Sample
{
    class Program
    {
        static async Task Main(string[] args)
        {
            NetworkCredential credential = new NetworkCredential("username", "password");

            using (WebdavClient client = new WebdavClient(credential))
            {
                client.BaseAddress = new Uri("https://myserver/dav/");

                // Lock the file for 10 minutes.
                ActiveLock fileLock = await client.Lock("documents/report.pdf", LockScope.Exclusive, Depth.Zero,
                    TimeSpan.FromMinutes(10), "John Smith");

                Console.WriteLine("Locked, token: " + fileLock.Token);

                // Other users cannot change the file now; this client can.
                await client.Upload("documents/report.pdf", "report.pdf");

                // Restart the timeout.
                fileLock = await client.RefreshLock(fileLock, TimeSpan.FromMinutes(10));

                await client.Unlock(fileLock);
                Console.WriteLine("Unlocked.");
            }
        }
    }
}

VB example

Imports System.Threading.Tasks
Imports Independentsoft.Webdav

Namespace Sample
    Module Program
        Sub Main(args As String())
            RunAsync().GetAwaiter().GetResult()
        End Sub

        Private Async Function RunAsync() As Task
            Dim credential As New NetworkCredential("username", "password")

            Using client As New WebdavClient(credential)
                client.BaseAddress = New Uri("https://myserver/dav/")

                ' Lock the file for 10 minutes.
                Dim fileLock As ActiveLock = Await client.Lock("documents/report.pdf", LockScope.Exclusive, Depth.Zero,
                    TimeSpan.FromMinutes(10), "John Smith")

                Console.WriteLine("Locked, token: " & fileLock.Token)

                ' Other users cannot change the file now; this client can.
                Await client.Upload("documents/report.pdf", "report.pdf")

                ' Restart the timeout.
                fileLock = Await client.RefreshLock(fileLock, TimeSpan.FromMinutes(10))

                Await client.Unlock(fileLock)
                Console.WriteLine("Unlocked.")
            End Using
        End Function
    End Module
End Namespace
