C# aspx頁面動態載入ascx使用者控制項 及 利用反射調用其內方法

//控制項代碼
public partial class WebUserControl : System.Web.UI.UserControl
{
    public void TestMethod(string strID)
    {
        this.TextBox1.Text += " WebUserControl:" + strID;
        //其他相關操作
    }
}

//控制項代碼
public partial class WebUserControl2 : System.Web.UI.UserControl
{
    public void TestMethod(string strID)
    {
        this.TextBox1.Text += " WebUserControl2:" + strID;
        //根據傳入參數進行其他相關操作
    }
}

//頁面代碼
public partial class Default1 : System.Web.UI.Page
{
    bool isShow = true;//是
    string strWebUserControls = "WebUserControl,WebUserControl2";
    protected void Page_Load(object sender, EventArgs e)
    {
        if (isShow)
        {
            string[] strUCs = strWebUserControls.Split(",".ToCharArray()[0]);
            for (int i = 0; i < strUCs.Length; i++)
            {
                string strUCName = strUCs[i].ToString();
                Control a = Page.LoadControl(strUCName+".ascx");
                a.ID = strUCName;
                this.Panel1.Controls.Add(a);
            }           
        } 
    }

    //頁面按鈕操作
    protected void Button1_Click(object sender, EventArgs e)
