                        #region

Firstly I want to understand what is the exact requirement. Can you explain with an example.

As per my understanding, you have a people picker field which has multiple users like User A, User B, User C, User D ......User N

Now you want, string first = "User A", string second = "User B" and string third = "User C;User D;.... User N"

If my understanding is correct, why don't you make use of SPFieldUserValueCollection.

Try something like below

SPFieldUserValueCollection userValueCollection = new SPFieldUserValueCollection();

userValueCollection = (SPFieldUserValueCollection)item["Internal name for To field"];

string first = String.Empty;
string second = String.Empty;
string third = String.Empty;


if(userValueCollection.Count > 0)
{
        first = userValueCollection[0].User.LoginName;
        second = userValueCollection[1].User.LoginName;

        for(int i=2;i<userValueCollection.Count;i++)
        {
               third += userValueCollection[i].User.LoginName+";";
        }

}


      

 

Its just a rough idea and the code is something in mind which I haven't tested. You may need to check for any syntax error that might have occured as I have not tested it.

 

 

Answer 3

this part looks suspicious:

String[] split = textbox.Split(new String[] { ";" }, StringSplitOptions.RemoveEmptyEntries);
String outputA1 = String.Format("{0}={1}", a1, split[0]);
String outputB1 = String.Format("{0}={1}", b1, split[1]);
String outputC1 = String.Format("{0}={1}", c1, split[2] + ";" + split[3]);

in this code you assume that "split" array always contains 4 elements. You should check the length of array before to write this code.
