Can you pass a variable for DSDateFrequency

Hi,

I'm using the .net API for DSWS

I want to retrieve the last available value and date from a time series for a date range.

Is it possible to pass in a variable for DSDateFrequency ?

DSDataRequest reqDSRequest = new DSDataRequest()

{

Instrument = new DSInstrument("VOD"),

DataTypes = new DSDataTypes("P"),

Date = new DSTimeSeriesDate(DSDateType.Absolute("01/01/2020"), DSDateType.Absolute("31/12/2022"), DSDateFrequency.Quarterly;

}

Thanks for reaching out to us.

Yes, you can set DSDateFrequency into a variable. The code looks like this:

var freq = DSDateFrequency.Quarterly;

DSDataRequest reqDSRequest = new DSDataRequest(){
    Instrument = new DSInstrument("VOD"),
    DataTypes = new DSDataTypes("P"),
    Date = new DSTimeSeriesDate(DSDateType.Absolute(new DateTime(2020, 1,1)), DSDateType.Absolute(new DateTime(2022, 12, 31)), freq)
            };

I created the freq variable for the DSDateFrequency enumeration. You can change it to other frequencies.

namespace Datastream.DswsApi
{   
    public enum DSDateFrequency
    {        
        None = 0,      
        Daily = 1,      
        Monthly = 2,     
        Weekly = 3,      
        Quarterly = 4,       
        Yearly = 5
    }
}

I hope that this information is of help.
