Question

I have Reporting Services running on SQL 2008 R2 and have a handful of reports that I created. I’m able to go into Report Server and set up a subscription and have any of the reports emailed to an email address. So all of that is configured correctly.

What I want to do is have a web page in my application that shows a list of available reports. The user can choose one, choose a schedule frequency, enter an email address, and click a ‘save’ button. When clicking save it should create the subscription in SSRS. I may need to pass in a couple report parameters depending on the report.

How can I do this in C#?

You can dynamically generate a one time subscription in SSRS for the report. You’ll have to use the RS webservice as mentioned by Diego.

Your code would look something like this:

static void generateSubscription()
{
    if (SubscriptionRequests.Count < 1) return;

    NetworkCredential credentials = new NetworkCredential("user", "pass");
    reports.ReportingService2005 rs = new reports.ReportingService2005();
    rs.Credentials = credentials;
    DateTime topDatetime = DateTime.Now;
    topDatetime = topDatetime.AddMinutes(2);

    foreach (SubscriptionRequest x in SubscriptionRequests)
    {
        reports.ExtensionSettings extensionSettings = new reports.ExtensionSettings();
        List<reports.ParameterValue> extParameters = new List<reports.ParameterValue>();
        List<reports.ParameterValue> parameters = new List<reports.ParameterValue>();
        string description = "Email: ";
        string eventType = "TimedSubscription";
        extensionSettings.Extension = "Report Server Email";

        string scheduleXml = "<ScheduleDefinition><StartDateTime>";
        scheduleXml += topDatetime.ToShortDateString() + " " + topDatetime.ToShortTimeString();
        scheduleXml += "</StartDateTime></ScheduleDefinition>";

        parameters.Add(new reports.ParameterValue() { Name = "abc", Value = x.id });


        extParameters.Add(new reports.ParameterValue() { Name = "RenderFormat", Value = x.renderFormat });
        extParameters.Add(new reports.ParameterValue() { Name = "TO", Value = x.email });
        extParameters.Add(new reports.ParameterValue() { Name = "ReplyTo", Value = x.replyTo });
        extParameters.Add(new reports.ParameterValue() { Name = "IncludeReport", Value = "True" });
        extParameters.Add(new reports.ParameterValue() { Name = "Subject", Value = "subject - " + " (" + x.id.ToString() + ")" });

        extParameters.Add(new reports.ParameterValue() { Name = "Comment", Value = x.body });
        extensionSettings.ParameterValues = extParameters.ToArray();

        description += topDatetime.ToShortDateString() + " " + topDatetime.ToShortTimeString();
        description += " (" + x.a + " - " + x.b + " - " + x.c + ")";
        string _reportName = "/report";
        rs.CreateSubscription(_reportName, extensionSettings, description, eventType, scheduleXml, parameters.ToArray());
        topDatetime = topDatetime.AddSeconds(30);
    }           
}
