How to call the method successively in C#? -

i saw code typed in java.

personinfo result = personinfobuilder             .setname("mistake")             .setage(20)             .setfavoriteanimal("cat")             .setfavoritecolor("black")             .setname("jdm")             .setfavoritenumber(7)             .build(); 

and tried in c# way.

public class personinfo {     public int age { get; set; }     public string name { get; set; } }  public class personbuilder {     private personinfo _personelement = null;      private int age;     private string name;      public void setage(int age)     {         this.age = age;     }      public void setname(string name)     {         this.name = name;     }      public personinfo getperson()     {         _personelement = _personelement ?? new personinfo();         _personelement.age = age;         _personelement.name = name;          return _personelement;     } }  class program {     static void main(string[] args)     {         personbuilder builder = new personbuilder();         builder.setname("he")                .setage(20);      } } 

and have error [resource not available anonymous access. client authentication required.],

how can call method successively in c# java ?

the code suggested called builder pattern. here how builder pattern in c# codes.

builder class

class personinfo     {         private string name, animan, color;         private int age, num;          private personinfo() { }          public class builder         {             personinfo info = new personinfo();              public builder setname(string name) { info.name = name; return this; }             public builder setage(int age) { info.age = age; return this; }             public builder setfavoriteanimal(string animan) { info.animan = animan; return this; }             public builder setfavoritecolor(string color) { info.color = color; return this; }             public builder setfavoritenumber(int num) { info.num = num; return this; }              public personinfo build()             {                 return info;             }         }     } 

and here how can use it.

personinfo.builder personinfobuilder = new personinfo.builder(); personinfo result = personinfobuilder                                     .setname("mistake")                                     .setage(20)                                     .setfavoriteanimal("cat")                                     .setfavoritecolor("black")                                     .setname("jdm")                                     .setfavoritenumber(7)                                     .build();
