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.
