c# - nested class used within base and derived classes -

i'm getting stack overflow exceptin in setter of code node nested data class

how should nested data class desc handled in base , derived classes, can use data in new nodes created in main window?

namespace lib {     // nested data class     public class desc     {         public desc(string shape, nullable<bool>[] inpins)         {             this.inpins = inpins;         }         string shape { get; set; }         nullable<bool>[] inpins { get; set; }     }      // base class drived shapenode class in vendor's framework     public class node : shapenode     {         public node()         {         }          // make copy of node         public node(node copy)          : base(copy)         {           text = copy.text;           nodeid = copy.nodeid;         }          public virtual node clone()         {            return new node(this);         }        // base constructor         public node(string text, desc nodeid)         {            this.text = text;            this.nodeid = nodeid;         }         new public string text { { return base.text; } set { base.text = value; } }         public desc nodeid { { return nodeid; } set { nodeid = value; }      } }     namespace test    {    // main window code public partial class mainwindow : window {      public mainwindow()      {           initializecomponent();           nodes = new node[]           {   new a(             "testa",              new desc(new nullable<bool>[]{false, false})),            new b(              "testb",               new desc(new nullable<bool>[] {false, false, false}))           }      }  } 

property getter (and setter) method special signature , name. can rewrite getter of nodeid as:

public desc get_nodeid() {        // recursive call     return get_nodeid(); } 

to solve problem, replace

public desc nodeid { { return nodeid; } set { nodeid = value; }} 

by

public desc nodeid { get; set; } 

in case have (when method isn't inlined):

public desc get_nodeid() {        // compiler-generated backing field     return _nodeid;  }
