Extension methode for web.AllowUnsafeUpdates

How we do it:

using (SPSite site = new SPSite(SPContext.Current.Site.Url))

            {

                using (SPWeb web = site.OpenWeb())

                {

                        web.AllowUnsafeUpdates = true;

                        SPList list = web.Lists.TryGetList("TestExtensionList");

                        SPListItem item = list.Items.Add();

                        item[SPBuiltInFieldId.Title] = TextBox1.Text.Trim();

                        item.Update();

                        web.AllowUnsafeUpdates = false;

                }

            }

How we can do it:

using (SPSite site = new SPSite(SPContext.Current.Site.Url))

            {

                using (SPWeb web = site.OpenWeb())

                {

                    web.DoUnsafeUpdate(delegate()

                    {

                        SPList list = web.Lists.TryGetList("TestExtensionList");

                        SPListItem item = list.Items.Add();

                        item[SPBuiltInFieldId.Title] = TextBox1.Text.Trim();

                        item.Update();

                    });  

                }

            }

Extension Methode to achieve the above code pattern:

public static class ExtensionMethodeClass

    {

        public static void DoUnsafeUpdate(this SPWeb web, Action action)

        {

            bool allowUnsafeUpdates = web.AllowUnsafeUpdates;

            web.AllowUnsafeUpdates = true;

            action();

            web.AllowUnsafeUpdates = allowUnsafeUpdates;

        }

    }
