May I know why that error keeps pointing to "String isEmailVerified ...."?
public JsonResult GetMemberCounts([FromBody] ChartFilterRequest filter)
{
DateTime startDate = DateTime.Parse(filter.MainFilter.First(m => m.Name == "startDate").Value as string);
DateTime endDate = DateTime.Parse(filter.MainFilter.First(m => m.Name == "endDate").Value as string);
String isEmailVerified = filter.MainFilter.First(m => m.Name == "isEmailVerified").Value as string;
var data = _dashboardComponent.GetMemberCount(startDate, endDate, isEmailVerified);
return new JsonResult(data);
}

Try using FirstOrDefault
and LastOrDefault
instead of First
and Last
, these methods will return the default value of the type they are invoked for if no elements match the lambda expression you provide as a parameter.
In your project, You just use filter.MainFilter.First(xxxx)
to select the data, So if no elements match the lambda expression you provide as a parameter,First()
will throw an exception, So here will report this error.
