How do I fix: Access to foreach variable in closure resharper warning?
I'm getting this ReSharper warning: Access to foreach variable in closure. May have different behaviour when compiled with different versions of compiler .
This is what I'm doing:
@foreach(var item in Model)
{
// Warning underlines "item".
<div>@Html.DisplayBooleanFor(modelItem => item.BooleanField)</div>
}
My extension is as follows:
public static MvcHtmlString DisplayBooleanFor<TModel, TValue>(
this HtmlHelper<TModel> helper,
Expression<Func<TModel, TValue>> expression)
{
bool value;
try
{
var compiled = expression.Compile()(helper.ViewData.Model);
value = Convert.ToBoolean(compiled);
}
catch (Exception)
{
value = false;
}
return MvcHtmlString.Create(value ? "Yes" : "No");
}
Note this is working as expected but how can I avoid this warning?
I'll appreciate any help provided.
块范围变量应解决警告。
@foreach(var item in Model)
{
var myItem = item;
<div>@Html.DisplayBooleanFor(modelItem => myItem.BooleanField)</div>
}
另一个选项是将JetBrains.Annotations.InstantHandleAttribute属性应用于DisplayBooleanFor方法。
