Mr. Rithik Banerjee....

In your code...
static ImageList _imageList;
public static ImageList ImageList
{
get
{
if (_imageList == null)
{
_imageList = new ImageList();
_imageList.Images.Add("Applications", Properties.Resources.Image_Applications);
_imageList.Images.Add("Application", Properties.Resources.Image_Application);
}
return _imageList;
}
}
What do you mean by Applications,Application, Image_Applcations and Image_Application....?

I think you need this: https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.treeview.imagelist?redirectedfrom=MSDN&view=netcore-3.1#System_Windows_Forms_TreeView_ImageList

I don't know how to add images to resource file....

First, add the images as resources and define your image list:
static ImageList _imageList;
public static ImageList ImageList
{
    get
    {
        if (_imageList == null)
        {
            _imageList = new ImageList();
            _imageList.Images.Add("Applications", Properties.Resources.Image_Applications);
            _imageList.Images.Add("Application", Properties.Resources.Image_Application);
        }
        return _imageList;
    }
}
Then, set the ImageList property of the TreeView:
treeView1.ImageList = Form1.ImageList;
Then, when you create the nodes, for a specific node, use:
applicationNode.ImageKey = "Application";
applicationNode.SelectedImageKey = "Application";
