'Date' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported

Question

I am trying to execute the following code and am receiving an error

public List GetLoggingData(DateTime LogDate, string title)
{
     var context          


        

Answer 1

Correct me if I'm wrong, but in mikemurf22's example, it would need to check each part of the date component, and potentially a lot more server processing?

Anyway, I stumbled across this problem, and this is my solution.

Assuming that you're going to be passing in the date component only, you can find the last minute of the day that you pass in, and use the where clause to define the range.

public List GetLoggingData(DateTime LogDate, string title)
{
    DateTime enddate = new DateTime(LogDate.Year, LogDate.Month, LogDate.Day, 23, 59, 59)

    var query = from t in context.Logs
                where t.Timestamp >= date
                where t.Timestamp <= enddate
                select t;

    return query.ToList();
}
