使用HTML.TextBoxFor遍历模型中的项目 [英] Using HTML.TextBoxFor to loop through items in a model

问题描述

可能是一个愚蠢的问题，但是我是MVC的新手.

到目前为止，在剃刀中我可以说@HTML.TextBoxFor(t => t.EmailAddress) 但现在我有一个for-each:

foreach(var q in Model.Questions)
{
  // so here the t => t.EmailAddress  syntax is not working anymore.
}

我在上面的代码示例中问了我的问题.因此，当我处于for-each循环内时，如何使用@HTML.TextBox?因为现在它不再使用lambda语法了.

解决方案

请勿使用foreach，因为当您尝试将输入绑定回模型时，这将导致问题.而是使用for循环:

for (var i = 0; i < Model.Questions.Count(); i++) {
    @Html.TextBoxFor(m => m.Questions[i])
}

Probably a stupid question but I am new to MVC.

So far in my Razor I could say @HTML.TextBoxFor(t => t.EmailAddress) but now I have a for-each:

foreach(var q in Model.Questions)
{
  // so here the t => t.EmailAddress  syntax is not working anymore.
}

I asked my question in the code sample above. So when I am inside a for-each loop how can I can use @HTML.TextBox ? because now it doesn't get the lambda syntax anymore.

解决方案

Do not use foreach, because this will cause problems when you try to bind your inputs back to the model. Instead use a for loop:

for (var i = 0; i < Model.Questions.Count(); i++) {
    @Html.TextBoxFor(m => m.Questions[i])
}
