Step 1: Create web application class to store details about web application like name, owner details.

  1. public class WebApplication
  2. {
  3. public string Name { get; set; }
  4. public string Value { get; set; }
  5. public List<NameValuePair> SiteCollections { get; set; }
  6. public string Owner { get; set; }
  7. public string Name_Owner
  8. {
  9. get
  10. {
  11. return string.Format("{0} ({1})", this.Name, this.Owner);
  12. }
  13. }
  15. public WebApplication()
  16. {
  17. this.Name = this.Value = string.Empty;
  18. this.SiteCollections = new List<NameValuePair>();
  19. }
  21. public WebApplication(string name)
  22. : this()
  23. {
  24. this.Name = this.Value = name;
  25. }
  26. public WebApplication(string name, string value)
  27. : this()
  28. {
  29. this.Name = name;
  30. this.Value = value;
  32. }
  33. }
Step 2: C# code to find All Web Applications.
  1. public class SharePointInformation
  3. private List<WebApplication> _allWebApplications;
  5. public List<WebApplication> GetAllWebApplication
  6. {
  7. get
  8. {
  9. if (_allWebApplications == null)
  10. {
  11. List<WebApplication> apps = new List<WebApplication>();
  13. try
  14. {
  16. SPServiceCollection services = SPFarm.Local.Services;
  17. foreach (SPService service in services)
  18. {
  19. if (service is SPWebService)
  20. {
  21. SPWebService webservice = (SPWebService)service;
  22. WebApplication webApps = new WebApplication();
  23. foreach (SPWebApplication webapp in webservice.WebApplications)
  24. {
  25. foreach (SPAlternateUrl spWebAppAlternateURL in webapp.AlternateUrls)
  26. {
  27. if (spWebAppAlternateURL.UrlZone == SPUrlZone.Default)
  28. {
  29. webApps = new WebApplication(webapp.Name, spWebAppAlternateURL.Uri.AbsoluteUri);
  30. foreach (string site in webapp.Sites.Names)
  31. {
  32. if (site == "")
  33. {
  34. webApps.SiteCollections.Add(new NameValuePair() { Name = "/", Value = "/" });
  35. }
  36. else
  37. webApps.SiteCollections.Add(new NameValuePair() { Name = site, Value = site });
  38. }
  40. apps.Add(webApps);
  41. }
  42. }
  43. }
  44. }
  45. }
  47. this._allWebApplications = apps;
  48. }
  49. catch(Exception ex)
  50. {
  51. MessageBox.Show(ex.Message);
  52. }
  53. }
  54. return this._allWebApplications;
  55. }
  58. set
  59. {
  60. this._allWebApplications = value;
  61. }
  62. }
