MethodInfo.Invoke跟进去执行了，但没执行成功

Question

MethodInfo.Invoke跟进去执行了，但没执行成功。
void button_Click(object sender, EventArgs e)
{
CSkinButton button = sender as CSkinButton;
if (button == null)
return;
MenuCD m = button.Tag as MenuCD;
if (m == null)
return;
Type typeinfo = typeof(SystemOptionForm);
object obj = Activator.CreateInstance(typeinfo);
System.Reflection.MethodInfo method = typeinfo.GetMethod(m.MenuFunction);
if (method == null)
return;
method.Invoke(obj, new object[] { button });
}
public void frm_AuthorityManager(CSkinButton button)
{
skinTabControl1.TabPages.Clear();
CCWin.SkinControl.SkinTabPage SkinTabPage = new CCWin.SkinControl.SkinTabPage();
SkinTabPage.Text = button.Text;
skinTabControl1.TabPages.Add(SkinTabPage);
AuthorityManagerControl AuthorityManagerControl = new AuthorityManagerControl();
AuthorityManagerControl.Dock = DockStyle.Fill;
SkinTabPage.Controls.Add(AuthorityManagerControl);
}
skinTabControl1.TabPages里的项一直没变，加上和不加没区别，在界面上也没变

找到问题了，不能同一个窗体类中调用方法，换个中间类就成功了。
