Programatically Check if the logged in user matches with user in a list item

Question

Hi All, 
I have a custom list with 1) title column 2) People column. 
I simple need to check if the logged in user = user in the column 2, and if yes fill a List<> with column 1 value. 
But when comparing, the value in list item is in different format than what we get by user.ToString() 
Following is what I tried: 
SPUser user = oWeb.CurrentUser;
List<String> usergrps = new List<String>();
foreach (SPListItem itemA in GrpSubsItems)
if (itemA["SubscribedBy"].ToString() == user.ToString())
usergrps.Add(itemA["Group"].ToString());
itemA["SubscribedBy"].ToString() gives = 10;#Some Name
where as user.ToString() gives = i:0#.w|domain\user 
Kindly guide if my approach is not correct. Thanks. 
Regards, Nayan

Hi Nayan,
Please modify the code like below:
SPUser user = oWeb.CurrentUser;
List<string> usergrps = new List<string>();
foreach (SPListItem itemA in GrpSubsItems)
string userName = itemA["SubscribedBy"] as string;
SPFieldUserValue userA = new SPFieldUserValue(itemA.ParentList.ParentWeb, userName);
if (userA.LoginName==user.LoginName)
usergrps.Add(itemA["Group"].ToString());
