my answerquestionmodel:

public string[] resultanswer { get; set; } 

my view:

@model list<surveytool.models.answerquestionviewmodel>     @for(int = 0; < model.count; i++)     {        @html.displayfor(m => m[i].resultanswer[i])     } 

xml answer data sample (will 'ssd' after extract):

<!--question configuration--><answerdata><answer>ssd</answer></answerdata> 

change

      public string[] resultanswer { get; set; } 

to

     public list<string>resultanswer { get; set; }  

and

     viewmodel.resultanswer = singlelineans.value;  

change

     viewmodel.resultanswer = new list<string>();      viewmodel.resultanswer .add(singlelineans.value);
