kendo tabstrip ArgumentOutOfRangeException

Question

我使用了kendo标签条，并尝试为模型集的每个项目显示一个标签。

@if (Model.Entities.Count > 1)
{
    @(Html.Kendo().TabStrip()
        .Name("tabstrip")
        .Items(items =>
        {
            for (int i = 0; i < Model.Entities.Count; i++)
            {
                items.Add()
                    .Text(Model.Entities[i].Name)
                    .Selected(i == 0)
                    .Content(@<div>
                                @Model.Entities[i].Name //causes exception
                            </div>
                            );
            }
        })
    )
}

标签内容（@ Model.Entities [i] .Name）中的标记会导致异常。

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

有谁知道我做错了什么或如何正确实现它？

您遇到了outer variable trap。

这对我有用：

@if (Model.Entities.Count > 1)
{
    @(Html.Kendo().TabStrip()
        .Name("tabstrip")
        .Items(items =>
        {
            for (int i = 0; i < Model.Entities.Count; i++)
            {
                var i1 = i;
                items.Add()
                    .Text(Model.Entities[i].Name)
                    .Selected(i == 0)
                    .Content(@<div>
                                @Model.Entities[i1].Name 
                            </div>
                            );
            }
        })
    )
}
