MVC4怎样在cshtml的引号内添加变量？

 @{int i = 0;}
            @foreach (var item in Model)
            {
                i++;
                <tr>                    
                    <td style="text-align:center">@item.SortCode</td>                    
                    <td style="text-align:center">@item.GROUP_CD</td>  
                    <td style="text-align:center">@item.AMT</td>
                    <td style="text-align:center">
                        <input type="hidden" id="group_cd@(i)" name="group_cd"@i value="@item.GROUP_CD" />
                        <input id="AMT"@i name="AMT@(i)" maxlength=" 50" type="text" class="txt" datacol="yes" err="新增" checkexpession="NumOrNull" style="width: 40px;color:red" onkeypress="return handleEnter(this, event)" />
                    </td>                 
                    <td style="text-align:left">@item.DESC</td>                
            </tr>
              
            }
