How to get Yesterday Date data using web api

[missy786]

I am trying to implement a method in api controller which only gets the yesterday date's data. I am new c# and mvc programming and I am not sure how to go about executing this task. I started the date method but currently its not filtering the data as desired and throwing error such as "Cannot convert lambda expression to type 'object[]' because it is not a delegate type"

public database_WICs Getdatabase_WICs(DateTime UploadDate)
 
        {
            string yesterday = DateTime.Today.AddDays(-1).ToShortDateString();
            database_WICs database_wics = db.database_WICs.Find(d => d.UploadDate == yesterday);
 
 
            if (database_wics == null)
            {
                throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotFound));
            }
 
            return database_wics;
        }

any help would be very much appreciated.
Thanks
