Now I want to split that whole string with white space and that new array will did not have duplicate entry.

How can I do this?

"This is my first post in stack overflow, I am very new in development and I did not have much more idea about the how to post the question."
    .Split()                       // splits using all white space characters as delimiters
    .Where(x => x != string.Empty) // removes an empty string if present (caused by multiple spaces next to each other)
    .Distinct()                    // removes duplicates

Distinct() and Where() are LINQ extension methods, so you must have using System.Linq; in your source file.

The above code will return an instance of IEnumerable<string>. You should be able to perform most operations required using this. If you really need an array, you can append .ToArray() to the statement.
