Question

Controller / C＃：

public Action GetData()
{
    ViewBag.InputData = new Dictionary<string, string>
    {
         ["Name"] = "Simon Lin",
         ["Age"] = "18"
    };
    return View();
}

查看/ HTML：

@foreach (var keyValuePair in (ViewBag.InputData as Dictionary<string, string>))
{
     <input type="text" name=@keyValuePair.Key value="" placeholder=@keyValuePair.Value />
}

但是在结果中，第一个输入的占位符只显示＆＃34; Simon＆＃34;，最终HTML：

<input type="text" name="Name" value="" placeholder="Simon" Lin="">

Answer 1

您在视图中的变量周围缺少引号：

<input type="text" name="@keyValuePair.Key" value="" placeholder="@keyValuePair.Value" />
                        ^                 ^                      ^                   ^

Answer 2

用引号括起名称和占位符

@foreach (var keyValuePair in (ViewBag.InputData as Dictionary<string, string>))
{
   <input type="text" name="@keyValuePair.Key" value="" 
 placeholder="@keyValuePair.Value"/>
}

ASP.NET MVC Dictionary <string，string>在视图中输出
