Fetch Unique name for a userid column in splist

Question

Hi,
I have a requirement. In my splist, I having a column named userid which is a user type column and it repeats multiple times.
Now, as I have created a web part which lists the "Name" column in a gridview based on the filtering.teh filtering rules is :
1) Fetch the current logged in user
2) Check whther the current logged in user's id present in this splist's UserId column.
3) If yes, I need to fetch the Name column for that row and come out of the loop
note: i didnt use CAML here.
Now, My issue is, though i  fetched this column,i am getting multiple entries of this userid.
I want to get the unique entry -[ i mean,  currentloggeduserid==UserId value of the column ]. i think  is there any way, i can get the Distinct entry of "Name" column/value by matching the userid. when i ran the below code,
i am getting multiple "Name" columns for the currentloggedinuser value.
but I need one and only one "Name"  column.
may i know  how to perform this.
should i apply join for this.
help is appreciated!
if (mlist != null && mlist.Items.Count > 0)
foreach (SPListItem oneitem in mlist.Items)
string[] character = { "\\" };
if (oneitem["UserID"] != null && !string.IsNullOrEmpty(oneitem["UserID"].ToString()) && varCurrentLoggedinUser != null)
string[] userName = oneitem["UserID"].ToString().Split(character, System.StringSplitOptions.None);
varCurrentUser = userName[1].ToString();
_mName = mWeb.Title.ToString();
if(varCurrentUser.Equals(varCurrentLoggedinUser))
isblnCurrUserin = true;
else
isblnCurrUserin = false;
if (isblnCurrUserin.Equals(true))
Dr1 = dt1.NewRow();
dr1[NAME] = _mName;
dt1.Rows.Add(dr1);
break;

Try this. My suggested changes are italic and underlined.
if (mlist != null && mlist.Items.Count > 0)
                                                        foreach (SPListItem oneitem in mlist.Items)
                                                            string[] character = { "\\" };
                                                            if (oneitem["UserID"] != null &&
!string.IsNullOrEmpty(oneitem["UserID"].ToString()) && varCurrentLoggedinUser != null)
                                                                string[] userName = oneitem["UserID"].ToString().Split(character,System.StringSplitOptions.None);
                                                                varCurrentUser = userName[1].ToString();
                                                                _mName = mWeb.Title.ToString();
                                                                if(varCurrentUser.Equals(varCurrentLoggedinUser))
isblnCurrUserin = true
Dr1 = dt1.NewRow();
dr1[NAME] = _mName;
dt1.Rows.Add(dr1);
break;
                                                                else
                                                                    isblnCurrUserin = false;
if(isblnCurrUserin)
break;
