Probably not, from your description.
A TextBox only holds Text - strings, and sorting is not one of it's features.
However, assuming your TextBox is multiline, it would be possible to put them into the TextBox in sorted order:

C#

struct MyStruct : IComparable
    {
    public string UserName;
    public int YearOfBirth;
    public MyStruct(string s, int i) { UserName = s; YearOfBirth = i; }

    public int CompareTo(object obj)
        {
        return YearOfBirth - ((MyStruct)obj).YearOfBirth;
        }
    }

    ...

    MyStruct[] arr = new MyStruct[]
       {
           new MyStruct("Joe", 1959),
           new MyStruct("Mike", 1972),
           new MyStruct("Aaron", 1999),
           new MyStruct("Jane", 1941)
       };
    Array.Sort(arr);
    List<string> lines = new List<string>();
    foreach (MyStruct ms in arr)
        {
        lines.Add(ms.UserName);
        }
    myTextBox.Lines = lines.ToArray();

The Solution 1 by OriginalGriff is very good. I have added this solution only to use LINQ by using the concept and data given by OriginalGriff in his solution.

C#

void Main()
{
    MyStruct[] arr = new MyStruct[]
       {
           new MyStruct("Joe", 1959),
           new MyStruct("Mike", 1972),
           new MyStruct("Aaron", 1999),
           new MyStruct("Jane", 1941)
       };
    myTextBox.Lines = arr.OrderBy (item => item.YearOfBirth).Select (item => item.UserName).ToArray();
}
struct MyStruct
{
    public string UserName;
    public int YearOfBirth;
    public MyStruct(string s, int i) { UserName = s; YearOfBirth = i; }
}
//TextBox.Lines will be
//Jane
//Joe
//Mike
//Aaron
