c# - Array Post Binding Asp Net MVC -

i'm having trouble binding arrays on asp net mvc, when object returns in post method, arrays properties returns null, here sample code made simulating problem:

any glue welcome :)

i have 2 classes:

  public class class1   {     public string sampleproperty { get; set; }     public class2[] sampleclass2array { get; set; }   }    public class class2   {     public string sampleproperty { get; set; }     public string[] samplestringarray { get; set; }   } 

this 2 actions:

public actionresult sampleaction() {   var model = new class1()   {     sampleproperty = "class 1 property 1 value",     sampleclass2array = new class2[]     {       new class2()       {         sampleproperty = "position 1 class 2 property 1 value",         samplestringarray = "one,two,3,4,5,6".split(new char[]{','})       },       new class2()       {         sampleproperty = "position 2 class 2 property 1 value",         samplestringarray = "seven,8,9,10".split(new char[]{','})       }     }   };    return view(model); } [httppost] public actionresult sampleaction(class1 model) {   dictionary<string, object> parameters = new dictionary<string, object>();   request.params.copyto(parameters);    return view(); } 

and view:

    <legend>class1</legend>     <div class="editor-label">         @html.labelfor(model => model.sampleproperty)     </div>     <div class="editor-field">         @html.editorfor(model => model.sampleproperty)         @html.validationmessagefor(model => model.sampleproperty)     </div>     <div class="editor-field">         @for (int = 0; < model.sampleclass2array.length; i++)         {             @html.editorfor(model => model.sampleclass2array[i]) <br />                            @html.hiddenfor(model => model.sampleclass2array[i])             }     </div>     <p>         <input type="submit" value="create" />     </p> 

with editortemplate

@model testbinding.models.class2 <p>     @html.editorfor(model => model.sampleproperty) </p> <p>     content</p> @for (int = 0; < model.samplestringarray.length; i++) {     @html.displayfor(model => model.samplestringarray[i]) <br />                    @html.hiddenfor(model => model.samplestringarray[i]) } <br /> 

and post returning (i took dictionary):

{[sampleproperty, class 1 property 1 value]}     {[sampleclass2array[0].sampleproperty, position 1 class 2 property 1 value]}     {[sampleclass2array[0].samplestringarray[0], one]}   {[sampleclass2array[0].samplestringarray[1], two]}   {[sampleclass2array[0].samplestringarray[2], 3]}     {[sampleclass2array[0].samplestringarray[3], 4]}     {[sampleclass2array[0].samplestringarray[4], 5]}     {[sampleclass2array[0].samplestringarray[5], 6]}     {[sampleclass2array[0], testbinding.models.class2]}  {[sampleclass2array[1].sampleproperty, position 2 class 2 property 1 value]}     {[sampleclass2array[1].samplestringarray[0], seven]}     {[sampleclass2array[1].samplestringarray[1], 8]}     {[sampleclass2array[1].samplestringarray[2], 9]}     {[sampleclass2array[1].samplestringarray[3], 10]}    {[sampleclass2array[1], testbinding.models.class2]}  

and model object in post view:

model   {testbinding.models.class1} testbinding.models.class1 sampleclass2array   {testbinding.models.class2[2]}  testbinding.models.class2[] [0] null    testbinding.models.class2 [1] null    testbinding.models.class2 sampleproperty  "class 1 property 1 value"  string
