当Backgrounworker Do-work执行时，属性值变为

Question

我想将文件分享给社交媒体。我已经获取文件列表并将其设置为应用程序对象属性，当form_Load执行时，文件列表值在applicationobject中。我在form_load中调用了backgroungworker在dowork中我要求使用从另一个类调用的方法执行某些操作。当dowork执行时，iam在应用程序对象中没有值。

这是我的代码

 private CloudBuddyApp applicationObject;
        public CloudBuddyApp ApplicationObject
        {
            get { return applicationObject; }
            set { applicationObject = value; }
        }

 enum ProcessType
        {
            PublicAcess
        }
 private void Form1_Load(object sender, EventArgs e)
        {
            try
            {
                processtype = ProcessType.PublicAcess;
                uxbackgroundWorker.RunWorkerAsync();
             }
            catch (Exception error)
            {
                CloudBuddyLog.WriteErrorInfo("Share.cs :: Form1_Load :" + error.Message);
            }

         }
 private void uxbackgroundWorker_DoWork(object sender, DoWorkEventArgs e)/// when it executes the count becomes zero in application
        {
            //try
            //{
                switch (processtype)
                {
                    case ProcessType.PublicAcess:
                        presenter.GetPublicURL();
                    break;
                }
            //}
            //catch(Exception error)
            //{
            //    CloudBuddyLog.WriteErrorInfo("Share.cs :: uxbackgroundWorker_DoWork:" + error.Message);
            //}
        }

        private void uxbackgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            try
            {
                switch (processtype)
                {
                    case ProcessType.PublicAcess:
                        presenter.setdata();
                        uxCommentTextBox.Text = generatedurl;
                    break;
                }
            }
            catch (Exception error)
            {
                CloudBuddyLog.WriteErrorInfo("Share.cs :: uxbackgroundWorker_RunWorkerCompleted:" + error.Message);
            }

        }
