String xmlstr = "XML string in the specified format ";

System. type T = typeof (entity class );

List <Object> olist = getobjectlist (xmlstr, t );

List <entity class> List = new list <entity class>

However, a problem exists here, that is, only the data list of the object class is obtained, and the list <Object> cannot be converted to the list <object class>, in this case, we can convert the data through traversal.

Foreach (Object o in olist)

{

List. Add (entity class) O );

}
