Shared locks and lock discovery

The following example shows you how to take a shared lock, which other users can share, and how to find out who holds locks on a file.

C# example

using System;
using System.Linq;
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/");

                if (!(await client.GetSupportedLocks("documents/report.pdf")).Contains(LockScope.Shared))
                {
                    Console.WriteLine("The server does not support shared locks.");
                    return;
                }

                ActiveLock sharedLock = await client.Lock("documents/report.pdf", LockScope.Shared, Depth.Zero,
                    TimeSpan.FromMinutes(10), "John Smith");

                foreach (ActiveLock activeLock in await client.GetLocks("documents/report.pdf"))
                {
                    Console.WriteLine(activeLock.Scope + " lock by " + activeLock.Owner + ", expires in " + activeLock.Timeout);
                }

                await client.Unlock(sharedLock);
            }
        }
    }
}

VB example

Imports System
Imports System.Linq
Imports System.Net
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/")

                If Not (Await client.GetSupportedLocks("documents/report.pdf")).Contains(LockScope.Shared) Then
                    Console.WriteLine("The server does not support shared locks.")
                    Return
                End If

                Dim sharedLock As ActiveLock = Await client.Lock("documents/report.pdf", LockScope.Shared, Depth.Zero,
                    TimeSpan.FromMinutes(10), "John Smith")

                For Each activeLock As ActiveLock In Await client.GetLocks("documents/report.pdf")
                    Console.WriteLine(activeLock.Scope.ToString() & " lock by " & activeLock.Owner & ", expires in " & activeLock.Timeout.ToString())
                Next

                Await client.Unlock(sharedLock)
            End Using
        End Function
    End Module
End Namespace
