Adding User to SharePoint Group through a custom ASP.NET web service.

I had a requirement to create a web service which would be used to add user to a SharePoint group. The code for it

[WebMethod]
public  string AddSharePointUser(string username,string password, string email){
string statusInfo = “”;
try{
string SharePointUrl = ConfigurationManager.AppSettings[“SharePointUrl”].ToString();
string SharePointGroup = ConfigurationManager.AppSettings[“SharePointGroup”].ToString();
SPSecurity.RunWithElevatedPrivileges(delegate(){
using (SPSite oSiteCollection = new
SPSite(SharePointUrl)){
oSiteCollection.AllowUnsafeUpdates = true;
using (SPWeb oWebsite = oSiteCollection.OpenWeb()){
oWebsite.AllowUnsafeUpdates = true;
SPUser spUser = oWebsite.EnsureUser(username);
SPGroup spGroup = oWebsite.SiteGroups[SharePointGroup];

spGroup.AddUser(spUser);
oWebsite.AllowUnsafeUpdates = false;

}

oSiteCollection.AllowUnsafeUpdates = false;

}});

statusInfo = “User Created Successfully”;

}
else{
statusInfo = “User Already Exists”;

}}
catch (Exception ex){
statusInfo = ex.Message;

}
return statusInfo;

}

To run the web service successfully, we need to set the identity of application pool of the web service to SharePoint Administrator account.

Hope it helps.
