ASP.NET Core MVC中IEnumerable视图模型的格式值如何？

Question

@Html.DisplayFor(modelItem => item.vouchertype == "P" ? "Paid" : "Receipt")

&

@Html.DisplayFor(modelItem => item.dated.ToString("dd-MMM-yy"))

Trying to format the value but error occurs:

Template can use only with field access, property access, single dimension array index or single parameter custom indexer experssions.

Answer 1

I assume posted lines are part of forech or other loop, and we speak about single item at that point.

In your Lambda expression you should use modelItem variable instead on item

@Html.DisplayFor(modelItem => modelItem.vouchertype == "P" ? "Paid" : "Receipt")

&

@Html.DisplayFor(modelItem => modelItem.dated.ToString("dd-MMM-yy"))

In Lambda expression rule is following:

x => x become your variable
