When the program runs for a long time and then avoids the program from suspended animation, a better way is to add a progress bar. If only your function is currently running, using the Dispatcher class is a simple and good choice.
This is achieved with the wpf window.
public partial class ProgressBarView : Window
{
ExternalCommandData m_commandData=null;
StrightRigidFrameBridgeModel m_model =null;
Element m_element = null;
ProgressModel m_ProgressModel;
bool applicationCancle =false;
public ProgressBarView(ExternalCommandData commandData, StrightRigidFrameBridgeModel model,Element elem)
{
InitializeComponent();
m_commandData = commandData;
m_model = model;
m_element = element;
ProgressModel pModel = new ProgressModel();
m_ProgressModel = pModel;
this.DataContext = pModel;
applicationCancle = false;
}
public void StrightRigidFrameBridgeCreater(ExternalCommandData commandData, StrightRigidFrameBridgeModel model, Element elem)
{
using (TransactionGroup transGroup = new TransactionGroup(commandData.Application.ActiveUIDocument.Document, "Creat Rebar"))
{
transGroup.Start("Creat Stright Rigid Frame Bridge");
ICollection<ElementId> elementIds = new List<ElementId>() { elem.Id };
for (int i = 0; i < (model.ListBoxGriderModel.Count - 1); i++)
{
m_ProgressModel.ProgressInfomation = "left" + (model.ListBoxGriderModel.Count - 1 - i-1).ToString() + "sections";
m_ProgressModel.ProgressValue= double.Parse(i.ToString())/ (model.ListBoxGriderModel.Count - 2) * 100;
System.Windows.Forms.Application.DoEvents();
BoxGriderModel boxGriderModelI = model.ListBoxGriderModel[i];
BoxGriderModel boxGriderModelJ = model.ListBoxGriderModel[i + 1];

The above code uses System.Windows.Forms.Application.DoEvents() to continuously switch the program back and forth between the thread and the main program, the program calculates a part, and then the progress bar updates the progress.
Use the Dispartcher class to pay attention to try catch and close the thread in time.
