c# - Get type programmatically and use it as a typeparam -

what want read in lex.db database. preferably paged pages of pre-defined size. have done following:

dbinstance database = getdatabase(); var tables = database.alltables(); foreach (var table in tables) {     string str = table.tostring();     str = str.replace("lex.db.dbtable`1[", string.empty);     str = str.replace("]", string.empty);     type t = type.gettype(str);      if (t != null)     {     var columns = database.readall<t>();     //handle columns     } } 

the problem function readall has typeparam. assumed use type typeparam, since represents class want results of.

however error:

"the type or namespace name 't' not found (are missing using directive or assembly reference?)".

so how can make actual type used typeparam instead of letter 't'?

edit:

based on suggestions romkyns , stefan steinegger gave tried using reflection. have following code:

dbinstance database = dbinstance.getinstance();  system.type thistype = database.gettype(); typeinfo thistypeinfo = thistype.gettypeinfo(); methodinfo method = thistypeinfo.getdeclaredmethod("loadall");  var tables = database.alltables(); foreach (var table in tables) {     string str = table.tostring();     str = str.replace("lex.db.dbtable`1[", string.empty);     str = str.replace("]", string.empty);     type t = type.gettype(str);     if (t != null)     {         methodinfo generic = method.makegenericmethod(t);         object[] parameters = { this, null };         var columns = generic.invoke(database, parameters);          if (columns != null)         {             //handle columns         }     } } 

this works point invoke method called. @ point following exception occurs:

an exception of type 'system.reflection.targetexception' occurred in mscorlib.dll not handled in user code

additional information: object not match target type.

any clues on how resolve this?

edit ii:

the invoke method had called as:

var columns = generic.invoke(database, null); 

the way make call use reflection. <t> supposed known @ compile time, in case isn't, therefore cannot that.

such apis come overload takes type directly though. check if yours has it. might this:

database.readall(t);
