C#

arr[0] = "Ram Vyas"

Try:

C#

string[] arr = "Ram Vyas; Sham Dass; Suresh Khanna;".Split(new char[]{';'}, StringSplitOptions.RemoveEmptyEntries);

this solved the last entry arr[3] = "";
this is removed
but how to resolve the leading extra space in following
arr[1] = " Sham Dass"
arr[2] = " Suresh Khanna"

Also I have to remove any duplicate entries in the array
thanks

Both of those require additional processing: one is a simple Trim call, but the other needs either a slightly complex loop, or a quick use of Linq methods: so the easiest solution is to use Linq methods for both:
string[] arr = "Ram Vyas; Sham Dass; Suresh Khanna;Sham Dass;".Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
arr = arr.Select(s => s.Trim()).Distinct().ToArray();
