To Generate Dynamic button
.cs page

    Button btnaddarray = new Button();
        btnaddarray.Text = "Add Array"; // Give text to respective button
        btnaddarray.ID = "BtnaddArray";   // provide id
        btnaddarray.Attributes.Add("Onclick", "BtnaddArray_Onclick"); // add event means when buton click  then event will be raised.



Now here i have called FunArray() function to generate dynamic controls in c# .
just copy or read this code and execute it.

private void FunArray()
    {
        int[] myArray = new int[10];
         myArray[0]=1;
        myArray[2]=2;
        myArray[3] = 3;
      
        Label lblPrintarrayvalue = new Label();
        lblPrintarrayvalue.Text =Convert.ToString("Array One:-" + myArray[0] +"Array Two:-"+"</Br>"+ myArray[1]+"Array

Three:-"+ myArray[2]+"<br/>");
        dvlabl.Controls.Add(lblPrintarrayvalue);
        lblPrintarrayvalue.ForeColor= System.Drawing.Color.Red;
        Response.Output.Write(lblPrintarrayvalue.Text);
        Response.Output.Write("<p>Your total is ${0:F2}</p>", lblPrintarrayvalue.Text);
        Response.Write(String.Format("<p>Your total is ${0:F2}</p>", lblPrintarrayvalue.Text));
        TextBox txttakeval = new TextBox();
        txttakeval.ID = "txtval";
        Label lblenterarray = new Label();
        lblenterarray.Text = "Enter Array List";
        txttakeval.Attributes.Add("Runat", "Server");
        Button btnaddarray = new Button();
        btnaddarray.Text = "Add Array";
        btnaddarray.ID = "BtnaddArray";
        btnaddarray.Attributes.Add("Onclick", "BtnaddArray_Onclick");

        btnaddarray.Click += new EventHandler(this.BtnaddArray_Onclick);
        dvlabl.Controls.Add(lblenterarray);
        dvlabl.Controls.Add(txttakeval);
        dvlabl.Controls.Add(btnaddarray);
      
      
      
    }

  private void BtnaddArray_Onclick(object sender, EventArgs e)
    {
//        your code

     
    }
