Try this:

da = new SqlDataAdapter("select emname from emp", con);
ds = new DataSet();
da.Fill(ds, "emp");
if(ds.Tables[0].Rows.Count > 0)
{
   string[] myArray = new string[ds.Tables[0].Rows.Count];
   for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
   {
       myArray[i] = ds.Tables[0].Rows[i]["emname"].ToString();
   }
   // Use myArray here...
}

Note that there are neater ways of doing this using LINQ, but if you’re quite new to C#/.NET I’d advise you to become familiar with the basics before diving into LINQ.
