    Control 'XXXX' accessed from a thread other than the thread it was created on

    在FORM初始化的时候加入

    Control.CheckForIllegalCrossThreadCalls = false;
    

    另一种方法

    delegate void DataGridView_Delegate(IEnumerable<CaseInfo> list);
    
     /// <summary>
     /// 向DataGridView绑定数据
     /// </summary>
     private void DataGridView_DataBind(IEnumerable<CaseInfo> list)
     {
        if (dgCaseInfo.InvokeRequired)
         {
           DataGridView_Delegate del = new DataGridView_Delegate(DataGridView_DataBind);
            dgCaseInfo.Invoke(del,list);
            return;
         }
    
           if (list == null)
           {
             dgCaseInfo.DataSource = null;
              return;
         }
    
                
    
                dgCaseInfo.DataSource =
                    new BindingList<ShowCaseInfo>(
                        list.Select(to => new ShowCaseInfo
                        {
                            Age = to.Age,
                            PatientName = to.PatientName,
                            CardId = to.CardId
                        }).ToList());
    
                dgCaseInfo.Columns[0].HeaderText = Resources.MainForm_DataGridView_DataBind_PatientName;
                dgCaseInfo.Columns[0].Width = 70;
                dgCaseInfo.Columns[1].HeaderText = Resources.MainForm_DataGridView_DataBind_Age;
                dgCaseInfo.Columns[2].Visible = false;
    
                tssl.Text = Resources.MainForm_BackgroundWorker_DoWork_Present_Complete;
            }
    

      

    ERROR:Object reference not set to an instance of an object

    如果是在异步中,报此错误,使用第二种方式可解决
