You can do like this

// find control
Control[] controls = this.Controls.Find("button1", true);

if (controls.Length > 0)
{

  Control control = controls\[0\];

  // get properties
  PropertyInfo\[\] properties = control.GetType().GetProperties();

  foreach (PropertyInfo controlProperty in properties)
  {

      // check property name
      if (controlProperty.Name == "Text")
      {
          // set value of control
          controlProperty.SetValue(control, "My new Value", null);
      }
   }

}
