C Method of Implementing Multi thread Operation Based on Delegation

In this paper, an example is given to describe the method of C # to realize the operation between multiple threads based on delegation. Share it for your reference, as follows:

Sometimes we have to have multiple threads, and more often, one thread may manipulate the attributes in other threads.
However, threads are concurrent, and 1-like calls cannot meet our requirements.
So, we can use the delegate here, and the code is as follows

private delegate void DelegateInfo();
private delegate void DelegateIsEnd();
// This is the method that a thread calls other threads 
private void Dowork()
{
  //  Determine whether it is necessary Invoke Required when multithreaded 
  if (this.InvokeRequired)
  {
    //  Call the program that writes the main line program control by delegate, and pass the parameters in object Array 
    this.Invoke(new DelegateInfo(LoadFile));
  }
  else
  {
    //  If no delegate call is required, call directly 
    this.LoadFile();
  }
  //========= Thread end ===========
  this.BeginInvoke(new DelegateIsEnd(ISEnd));
}
private void ISEnd()
{
  wf.Visible = false;
  wf.Close();
  wf.Dispose();
}
private void LoadFile()
{
}
private WaitingForm wf = nu

I hope this article is helpful to everyone's C # programming.
