c# - JSON to List<class> & List<class> to JSON? -

hi guys how work? searched in , promissing doesnt work either.

errormessage:

the deserialized type should normal .net type (i.e. not primitive type integer, not collection type array or list) or dictionary type (i.e. dictionary).

so how split individual objects json?

list<class> = jsonconvert.deserializeobject<list<class>>(json_string) 

the json string:

{ "spalten": [{     "nummer": 1,     "name": "breite",     "typ": "double",     "laenge": 0,     "einheit": "m",     "editierbar": true,     "optional": true,     "layer": null,     "layer_spalte": null,     "d_spal_name": null,     "d_spal_min": 0,     "d_spal_max": null,     "d_spal_val": null }, {     "nummer": 2,     "name": "kommentar",     "typ": "string",     "laenge": 255,     "einheit": null,     "editierbar": true,     "optional": true,     "layer": null,     "layer_spalte": null,     "d_spal_name": null,     "d_spal_min": null,     "d_spal_max": null,     "d_spal_val": null }] } 

here class:

    public class config_class {      private int _nummer;     public int nummer     {         { return _nummer; }         set { _nummer = value; }     }      private string _name;     public string name     {         { return _name; }         set { _name = value; }     }      private string _typ;     public string typ     {         { return _typ; }         set { _typ = value; }     }      private double _laenge;     public double laenge     {         { return _laenge; }         set { _laenge = value; }     }      private string _einheit;     public string einheit     {         { return _einheit; }         set { _einheit = value; }     }      private bool _editierbar;     public bool editierbar     {         { return _editierbar; }         set { _editierbar = value; }     }      private bool _optional;     public bool optional     {         { return _optional; }         set { _optional = value; }     }      private string _layer;     public string layer     {         { return _layer; }         set { _layer = value; }     }      private int _layer_spalte;     public int layer_spalte     {         { return _layer_spalte; }         set { _layer_spalte = value; }     }      private string _d_spal_name;     public string d_spal_name     {         { return _d_spal_name; }         set { _d_spal_name = value; }     }      private int _d_spal_min;     public int d_spal_min     {         { return _d_spal_min; }         set { _d_spal_min = value; }     }      private int _d_spal_max;     public int d_spal_max     {         { return _d_spal_max; }         set { _d_spal_max = value; }     }      private string _d_spal_val;     public string d_spal_val     {         { return _d_spal_val; }         set { _d_spal_val = value; }     }   } 

(i encode again later) thank you!

sorry cannot put comments yet first,you have type mismatch between data , convert class: layer_spalte, d_spal_min , d_spal_max null in data. put try putting array inside class

this code has work you:

public class myclass {     public spalten[] spalten { get; set; } }  public class spalten {     public int nummer { get; set; }     public string name { get; set; }     public string typ { get; set; }     public int laenge { get; set; }     public string einheit { get; set; }     public bool editierbar { get; set; }     public bool optional { get; set; }     public string layer { get; set; }     public int? layer_spalte { get; set; }     public string d_spal_name { get; set; }     public int? d_spal_min { get; set; }     public int? d_spal_max { get; set; }     public string d_spal_val { get; set; } } 

and

  myclass = jsonconvert.deserializeobject<myclass>(json_string)
