在剃须刀内循环

Question

我为每个控件分配了字段名称“GroupTitle”。我想遍历分配给特定组的 Control 的每个元素。

public class Groups
{
    public virtual int Id { get; set; }
    public virtual string GroupTitle { get; set; }

}

public class Controls
{
    public int Id { get; set; } //Id
    public string Name { get; set; } //name of control/element
    public string ControlType { get; set; }  // checkbox, radio button, textbox, time, date
    public string Caption { get; set; } //caption/title/label        
    public string Content { get; set; } //in case of checkbox        
    public bool Mandatory { get; set; } //is mandatory to select or enter its value.                 
    public string GroupTitle { get; set; } // there will be title at the top of controls if grouped together                

    //public List<SelectListItem> SelectOptions { get; set; } //select/dropdown options e.g. Pakistan, Uk for country dropdown        

}

下面是我的代码。我不确定如何在嵌套循环中访问模型变量。这给了我错误。它还给我错误，即 Where 子句不存在。

@foreach (var groups in Model.Groups)
{                                                    
    foreach (var row in Model.Controls.Where("GroupTitle ==",  @groups.GroupTitle;))
    {   

    }
}

证明这一点：

@foreach (var groups in Model.Groups)
{                                                    
    foreach (var row in Model.Controls.ToList().Where(x => x.GroupTitle == groups.GroupTitle))
    {   

    }
}

我认为this answers 可能也适用于您的情况。
