Razor - First Element of ForEach or ForEach Loop only once-CodePudding

I would like this ForEach to return h3 to me only once, instead of three which is the length of the array. How can I do? Thanks to those who will answer

 @foreach (var winelistObj in Model.winetype.Where(s => s.name == Request.Query["wine"]))
{
 <h3 >@winelistObj.name</h3>
}

CodePudding user response：

@foreach (var winelistObj in Model.winetype.Where(s => s.name == Request.Query["wine"]).FirstOrDefault())
{
 <h3 >@winelistObj.name</h3>
}

This should give you the first result of the array.

Maybe you want to concat all matching wines comma separated, then use string.Join:

@{ string matchingWines = string.Join(",", Model.winetype.Where(s => s.name == Request.Query["wine"]).Select(w=> w.name)); }
<h3 >@matchingWines</h3>

You could add an if(!string.IsNullOrEmpty(matchingWines)) { ... } so that you don't render the h3 if there was no matching wine or render a different message.
