The attached code is working. However, we won't know how rows will be returned into
string[] x = new string[?].

For now, I hard code to 3. How can I handle the code without knowing the number of rows in a array?

You could use a List<string> instead. That would get you dynamic addition of items. If you truly need an array in the end, you can simply call the ToArray method of the List class.

e.g.

using System.Collections.Generic;

...

List<string> x = new List<string>();

for (int i = 0; i < dt.Rows.Count; i++)
{
    x.Add(dt.Rows[i]["ViewName"].ToString());
}

// If you need an array
string[] y = x.ToArray();

Your GetBondViewList method will return an array, so if you are asking how to inspect the values that it returns, then you can do something like:

string[] result = GetBondViewList("some code", string "some sub code", 1);

if (result != null)
{
    for (int i = 0; i < result.Length; i++)
    {
        Console.WriteLine(result[i]);
    }
}
