    Accessing the Public Data API with C#

    On This Page:

    API Version 2.0 C# Sample Code

    Single Series

    Here is an example of how to use POST method in c# (Version 2.0, single series):

    //Post request example version 2.0
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.bls.gov/publicAPI/v2/timeseries/data/");
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Method = "POST";
    //Using Javascript Serializer
    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
      var jS = new JavaScriptSerializer();
      var newJson = jS.Serialize(new SeriesPost()
      {
          seriesid = (new List() { "CUUR0000SA0" }).ToArray(),
          startyear = "",
          endyear = "",
          catalog = true,
          calculations = true,
          annualaverage = true,
          registrationKey = "EnterRegistrationKeyHere"
      });
      //View the JSON output
      System.Diagnostics.Debug.WriteLine(newJson);
      streamWriter.Write(newJson);
      streamWriter.Flush();
      streamWriter.Close();
    }
    

    Multiple Series

    Here is an example of how to use POST method in c# (Version 2.0, multiple series):

    //Post request example version 2.0
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.bls.gov/publicAPI/v2/timeseries/data/");
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Method = "POST";
    //Using Javascript Serializer
    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
      var jS = new JavaScriptSerializer();
      var newJson = jS.Serialize(new SeriesPost()
      {
          seriesid = (new List() { "CUUR0000SA0", "WPUSOP3000" }).ToArray(),
          startyear = "",
          endyear = "",
          catalog = true,
          calculations = true,
          annualaverage = true,
          registrationKey = "EnterRegistrationKeyHere"
      });
      //So you can see the JSON thats output
      System.Diagnostics.Debug.WriteLine(newJson);
      streamWriter.Write(newJson);
      streamWriter.Flush();
      streamWriter.Close();
    }
    

    One or More Series with Optional Parameters

    Here is an example of how to use POST method in c# (Version 2.0, one or more series with optional parameters):

     

    //Post request example version 2.0
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.bls.gov/publicAPI/v2/timeseries/data/");
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Method = "POST";
    //Using Javascript Serializer
    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
      var jS = new JavaScriptSerializer();
      var newJson = jS.Serialize(new SeriesPost()
      {
          seriesid = (new List() { " CUUR0000SA0" }).ToArray(),
          startyear = "2010",
          endyear = "2015",
          catalog = true,
          calculations = true,
          annualaverage = true,
          registrationKey = "EnterRegistrationKeyHere"
      });
      //View the JSON output
      System.Diagnostics.Debug.WriteLine(newJson);
      streamWriter.Write(newJson);
      streamWriter.Flush();
      streamWriter.Close();
    }
    

     

    API Version 1.0 C# Sample Code

    Single Series

    Here is an example of version 1.0 single series:

     

    //Post request example version 1.0
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.bls.gov/publicAPI/v1/timeseries/data/CUUR0000SA0");
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Method = "POST";
    

    Multiple Series

    Here is an example of version 1.0 multiple series:

     

    //Post request example version 1.0
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.bls.gov/publicAPI/v1/timeseries/data/");
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Method = "POST";
    //Using Javascript Serializer
    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
      var jS = new JavaScriptSerializer();
      var newJson = jS.Serialize(new SeriesPost()
      {
          seriesid = (new List() { "CUUR0000SA0", "WPUSOP3000" }).ToArray(),
          startyear = "",
          endyear = "",
          catalog = true,
          calculations = true,
          annualaverage = true,
      });
      //So you can see the JSON thats output
      System.Diagnostics.Debug.WriteLine(newJson);
      streamWriter.Write(newJson);
      streamWriter.Flush();
      streamWriter.Close();
    }
    

    Multiple Series, Multiple Years

    Here is an example of version 1.0 multiple series specifying years:

     

    //Post request example version 1.0
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.bls.gov/publicAPI/v1/timeseries/data/");
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Method = "POST";
    //Using Javascript Serializer
    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
      var jS = new JavaScriptSerializer();
      var newJson = jS.Serialize(new SeriesPost()
      {
          seriesid = (new List() { "CUUR0000SA0", "WPUSOP3000" }).ToArray(),
          startyear = "2010",
          endyear = "2015",
          catalog = true,
          calculations = true,
          annualaverage = true,
      });
      //So you can see the JSON thats output
      System.Diagnostics.Debug.WriteLine(newJson);
      streamWriter.Write(newJson);
      streamWriter.Flush();
      streamWriter.Close();
    }
