kendo tabstrip ArgumentOutOfRangeException

Question

我使用kendo選項卡條並嘗試顯示模型集合中每個項目的選項卡。

@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> 
          ); 
      } 
     }) 
    ) 
} 

在選項卡內容的標記（@ Model.Entities [I]請將.Name）導致異常。

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

有沒有人知道我在做什麼錯或如何正確實施它？

您曾遇到過outer variable trap。

這爲我工作：

@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> 
          ); 
      } 
     }) 
    ) 
}
