Get record base on ID.

Guest User

I have use this code get record list base on id but face a issue

string Categoryid = HttpContext.Request.Query["CatgeoryId"].SingleOrDefault();

var result = customEntityResult.Items.Select(x => (BlogPostDataModel)x.Model).Where(x => x.CategoryIds == Convert.ToInt32(Categoryid)).ToList());

Operator '==' cannot be applied to operands of type 'ICollection' and 'int'--this issue face

yes this is a valid error , you can not compare collection of integers and a single integer, your CategoryIds is a collection. so, instead you can use contains like shown below.
var result = customEntityResult.Items.Select(x => (BlogPostDataModel)x.Model).Where(x => x.CategoryIds.contains( Convert.ToInt32(Categoryid))).ToList());
