Overview¶

This article provides a means of downloading all the reports from an SSRS by way of a C# Console Application.

Prerequisites¶

• You must have credentials to the SSRS (i.e., the "ReportServer") database with at least read access
• The IP address where this code runs must be whitelisted (or at least not blocked by a firewall) on the SSRS server.
  

Code¶

Program.cs¶

class Program
{
    static void Main(string[] args)
    {
        var asm = Assembly.GetEntryAssembly();

        var pathItems = Path.GetDirectoryName(asm.Location).Split('\\');

        var rootFolder = Path.Combine(string.Join('\\', pathItems.Take(pathItems.Length - 3)), "Reports");

        var ssrs = new SsrsEngine();

        ssrs.DownloadReports(rootFolder);
    }
}

SsrsEngine.cs¶

/*
    Packages Required

    (2) System.Data.SqlClient

using Microsoft.Extensions.Configuration;
using System.Data.SqlClient;
using System.IO;

public class SsrsEngine
{
    public void DownloadReports(string rootFolder)
    {
        var config = GetConfiguration();

        var cs = config.GetConnectionString("SsrsCatalog");

        var dbServer = GetConnectionStringServerName(cs);

        using (var conn = new SqlConnection(cs))
        {
            conn.Open();

            var sql = @"
                    select

                    }

                    var rdlContent = reader.GetString(1);

                    /* The first three bytes of the content seem to be garbage. */
                    if (rdlContent.Length > 3)
                    {
