c# - Deferred type inference for inherited class method -

what i'm trying do, without success, method on base class that, using reflection, update properties defined inherited classes. so, starting specific method this

/** fill item xml node  */ public tblitem fromxml (xmlnode itemnode) {     foreach (xmlnode itemfield in itemnode) {         type mytype = this.gettype ();         propertyinfo mypropinfo = mytype.getproperty (itemfield.name);         if (mypropinfo != null) {             mypropinfo.setvalue (this, convert.changetype (itemfield.innertext, mypropinfo.propertytype), null);         } else {                         throw new missingfieldexception (string.format ("[fieldname]wrong fieldname: {0}", itemfield.name));         }     }     return this; } 

i need defined in base class called i.e. tblbase, containing no properties @ all, , being used seamlessly in derived classes, i.e. tblderived1: tblbase etc. in there different properties defined each of them, i'm here asking: there way or dream of dirty mind? btw, how need use stuff:

    xmldoc.load (xmldbpath);      xmlnodelist itemnodes = xmldoc.selectnodes (nodes2select);     //tblitem inherits tblbase     tblitem ti = new tblitem ();     foreach (xmlnode itemnode in itemnodes) {         print (((tblitem)ti).fromxml (itemnode).tostring ());     } 

see code using generics below, replaced xml node name , value test.

  public t fromxml<t>(string name, string value) t: tblbase             {                 type mytype = this.gettype();                 propertyinfo mypropinfo = mytype.getproperty(name);                 if (mypropinfo != null)                 {                     mypropinfo.setvalue(this, convert.changetype(value, mypropinfo.propertytype), null);                 }                 else                 {                     throw new missingfieldexception(string.format("[fieldname]wrong fieldname: {0}", name));                 }                 return (t)this;             } 

and calling it: var result = youritem.fromxml(somename, somevalue);

but, work without generics well:

    public tblbase fromxml (xmlnode itemnode) {     foreach (xmlnode itemfield in itemnode) {         type mytype = this.gettype ();         propertyinfo mypropinfo = mytype.getproperty (itemfield.name);         if (mypropinfo != null) {             mypropinfo.setvalue (this, convert.changetype (itemfield.innertext, mypropinfo.propertytype), null);         } else {                         throw new missingfieldexception (string.format ("[fieldname]wrong fieldname: {0}", itemfield.name));         }     }     return this; } 

and calling it: tblitem result = (tblitem)youritem.fromxml(...);

edit:

this work on properties (with , set). if have field data members want change in same way, need use getfield instead of getproperty:

var myfieldinfo = mytype.getfield(name) ... myfieldinfo.setvalue (this, convert.changetype (itemfield.innertext, myfieldinfo.fieldtype));
