c# - Getting primary key from the database -


i created method traverses data returned primary key in repeat structure following error occurs, can not implicitly convert type "system.attribute" "bool"

  using system;   using system.collections.generic;   using system.componentmodel;   using system.data.sqlclient;   using system.linq;   using system.reflection;    using system.web;        update  private void setself(cliente entity)     {          foreach (propertyinfo pro in entity.gettype().getproperties())         {               if (this.gettype().getproperty(pro.name).getcustomattribute(typeof(dataobjectfieldattribute != null))             this.gettype().getproperty(pro.name).setvalue(this, pro.getvalue(entity));          }      }

because line: this.gettype().getproperty(pro.name).getcustomattribute(typeof(dataobjectfieldattribute) return system.attribute, if looking bool.

don't want add check ?

if (this.gettype().getproperty(pro.name).getcustomattribute(typeof(dataobjectfieldattribute) != null){ }
