SharePoint how to check user, CurrentUser is in perticuler site group

You wants to check if CurrentUser or particular User / SPUser is present in specific site's permission group or not,
Usually site have three groups Visitors, Members and Owners. If you have create another group and wants to check if particular user is present is that group for some validation so you can refer below code sample,

* Assuming you have basic knowledge of SharePoint coding.

Code:

private bool UserPresentInGroup(string groupName)
        {
            bool isAdmin = false;
            try
            {
                SPSecurity.RunWithElevatedPrivileges(delegate()
                { // User may not have permission to see site group or Group members....
                    using (SPSite oSite = new SPSite(strWebUrl))
                    {
                        using (SPWeb oWeb = oSite.OpenWeb())
                        {
                            SPGroup oUserGroup = oWeb.Groups[groupName];
                            foreach (SPUser item in oUserGroup.Users)
                            {
                                if (item.LoginName == currentUser.LoginName)
                                {
                                    isAdmin = true;
                                }
                            }
                        }
                    }
                });
            }
            catch (Exception exp)
            {}// Catch exception

If you wants to check user from Sites default Visitor, Member or Owner Group you can directly get group by below property

• SPWeb.AssociatedVisitorGroup
• SPWeb.AssociatedMemberGroup
• SPWeb.AssociatedOwnerGroup

instead of  oUserGroup.
