    public int ID;
    public string Ad;
    public string SoruIcerik;
    public string Cevap;
    public int Sira;

    public Soru()
    {

//here is controller

You have written the wrong syntax here:

@Html.TextAreaFor(m => m.SoruIcerik, new { @name = "soruIcerik", @id = "soruIcerik", @rows = "10", @cols = "80" })

which should be like this:

@Html.TextAreaFor(m => m.SoruIcerik, new { @name = "SoruIcerik", @id = "SoruIcerik", @rows = "10", @cols = "80" })

name and id was "soruIcerik" which must match to the property name "SoruIcerik".

Or you can simply write like this:

@Html.TextAreaFor(m => m.SoruIcerik, new {@rows = "10", @cols = "80" })

The control will render in html something like this:

<textarea id="SoruIcerik" name="SoruIcerik" rows="10" cols="80"></textarea>

Here name and id must be the same as property defined in the model.

You need to make the class variables as Properties. Like:

public class Soru
{
    public int ID {get;set};
    public string Ad {get;set};
    public string SoruIcerik {get;set};
    public string Cevap {get;set};
    public int Sira {get;set};
}
