C# 等待界面跨线程调用,该怎么解决

C# 等待界面跨线程调用

C# code

Loading.Wait wait = new Loading.Wait("数据加载中...");        private void myListView_ItemActivate(object sender, EventArgs e)        {            new Action(OpenEmr).BeginInvoke(new AsyncCallback(wait.CloseLoading), null);            wait.ShowDialog();        }        delegate void EmrEvent(object[] pa);        private void OpenEmr()        {            object[] pa = (object[])this.myListView.SelectedItems[0].Tag;            MRWriterForm writerForm = new MRWriterForm();            writerForm.WindowState = FormWindowState.Maximized;            PatientDetail patientdetail = pa[0] as PatientDetail;            writerForm.Patient = patientdetail;            //病历已经完成不可以修改            if (patientdetail.EMRState == (int)EMRState.Complete)            {                return;            }            //writerForm.ShowDialog(this.ParentForm);            writerForm.ViewFirstPage();            writerForm.Show();        }        private void allListView_MouseDoubleClick(object sender, MouseEventArgs e)        {            //双击设置患者的管床医师            if (MessageBox.Show("是否将自己设置为该患者的经治医师？", "确认", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)            {                return;            }            //更新患者的经治医师            DeptAdmission deptadmission = new DeptAdmission();            object[] obj = this.allListView.SelectedItems[0].Tag as object[];            deptadmission = obj[1] as DeptAdmission;            deptadmission.MangerDoc = LoginInfo.Employee.EmployeeID;            deptadmission.Update();        }

这个代码提示线程间操作无效: 从不是创建控件“myListView”的线程访问它。

在这一行 object[] pa = (object[])this.myListView.SelectedItems[0].Tag;

请问如何修改呢 谢谢


[解决办法]

C# code

public delegate void NormalCallBack();private void myListView_ItemActivate(object sender, EventArgs e)        {            new Action([color=#FF0000]OpenEmr_Ex[/color]).BeginInvoke(new AsyncCallback(wait.CloseLoading), null);            wait.ShowDialog();        }public void OpenEmr_Ex(){if (this.InvokeRequired)            {                NormalCallBack ncb = new NormalCallBack(OpenEmr_Ex);                this.BeginInvoke(ncb);            }            else            {OpenEmr();}}
