How to upload parameters to methods in the delegate method in a thread

Recently, when optimizing my previous projects, I need to pass an object to the methods in the original delegate method, and I want to use this object to dynamically generate a DataTable. An error is reported during running: "The control created on a thread cannot be the parent level of the Control created on another thread ".

So I declare a delegate again, and then I use multithreading again in the method, start another method in this thread to complete the work I want, and then delegate it to another method for implementation.

I am dizzy... Let's talk about it in code. 1 public delegate void data_1Callback (DataTable dataTable); // delegate the DATATABLE operation
2
3Remote. RemoteServer. UserCome + = new Remote. UserComeHandler (RemoteServer_UserCome );
4. This is another delegate of the method in the thread at startup.
5
6 public void RemoteServer_UserCome (object o, string user, string userIP)
7 {stopThread (); // stop the thread beforehand
8 t = new Thread (new ThreadStart (BindDataGrid ));
9 t. Start ();
10
11}
12
13 void stopThread ()
14 {
15 if (t! = Null) & (t. IsAlive ))
16 {
17 t. Abort ();
18 t. Join ();
19}
20 t = null;
21}
22
23 public void BindDataGrid ()
24 {
25 if (dtUser. Rows. Count <1)
26 {
27 ColId. DataType = System. Type. GetType ("System. Int32 ");
28 dtUser. Columns. Add ("ID ");
29 ColDateTime. DataType = System. Type. GetType ("System. String ");
30 dtUser. Columns. Add ("launch time ");
31 dtUser. Columns. Add ("User Name ");
32 dtUser. Columns. Add ("current state ");
33 dtUser. Columns. Add ("Exit Time ");
34 dtUser. Columns. Add ("Internet IP ");
35 dtUser. Columns. Add ("intranet IP ");
36}
37 count ++;
38 DataRow dr = dtUser. NewRow ();
39
40 dr [0] = count;
41 dr [1] = DateTime. Now. ToString ();
42 dr [2] = userName;
43 dr [3] = "online ";
44 dr [4] = "";
45 dr [5] = NetIp;
46 dr [6] = WokIp;
47
48 dtUser. Rows. Add (dr );
49
50dgUser. Invoke (new data_1Callback (data_1), new object [] {dtUser });
51}
52
53 private void data_1 (DataTable dataTable)
54 {
55 try
56 {
57 this. dgUser. DataSource = dataTable;
58 this. dgUser. Refresh ();
59}
60 catch (Exception ex)
61 {
62 MessageBox. Show (ex. Message. ToString ());
63}
64}

It seems a little messy. Leave me a message if you don't understand it.
