SPuser to find group membership

I have a code in which I have to check if a user is a part of a certain group (lets say "GroupA").

I have the user details stored in the Sharepoint variable SPUser. Now I need to check if this user is a part of GroupA and then take some action.

How can I achieve this?

Solution

  • Source : How to check if a user exists in a group

    you can use following extension method, like this:

    public static bool InGroup(this SPUser User, string GroupName)
{
    return User.Groups.Cast<SPGroup>().Any(g => g.Name.ToLower() == GroupName.ToLower());
}

    Then call it like this:

    bool inGroup = spuser.InGroup("GroupName");

    If you want to check the current user then another approach can be like this:
    From: Check user already exist in specified SharePoint Group

    SPWeb web = SPContext.Current.Web;
SPGroupCollection webGroups = web.Groups;

foreach (SPGroup group in webGroups)
{
 //Checking the group
 if (group.ContainsCurrentUser)
 {
  // perform action
 }
 else
 {
  //perform action
 }
}
