MVC 将消息从部分视图传递到视图

Question

我有部分看法

  if (CompanyFound != null)
{
    Products = DB.tblBuyOnlineMasters.Where(c => c.CompanyID == CompanyID).OrderByDescending(p => p.BuyOnlineID).ToList();
    if (Products.Count < 1)
    {
        ViewBag.Msg = "No products found for this company";
    }
}
else
{
    ViewBag.Msg = "Company Not Found (Showing result from all companies)";
}

我需要在主视图中显示数据

<div class="col-sm-8" style="background-color: rgb(231, 231, 231)">
    @{                  
        Html.RenderPartial("ProductRepeater");                  
    }             

        <h4 style="text-align: center;">
            @ViewBag.Msg
        </h4>                         
</div>

ViewBag 方法未传输数据

Answer 1

我能够通过替换

来携带数据

ViewBag.Msg

由

TempData["Msg"]

我想知道这样是否可以，或者 MVC 中是否还有其他方法

看起来像

<div class="col-sm-8" style="background-color: rgb(231, 231, 231)">
    @{                  
        Html.RenderPartial("ProductRepeater");                  
    }             
        <h4 style="text-align: center;">
            @TempData["Msg"]
        </h4>
</div>
