我有数组str[0]="12",str[1]="34",str[2]="",str[3]="56",str[4]="78",str[5]="",str[6]="",str[7]="90"
请问如果去掉空数组项，形成新的数组str[0]="12",str[1]="34",str[2]="56",str[3]="78",str[4]="90"
如果解决？谢谢

using System;
using System.Collections.Generic;
using System.Text;

namespace arraytest1
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] str = {"12","34","","56","78","","","90"};
            int i = 0;
            foreach (string temp in str)
                if (!"".Equals(temp))
                    str[i++] = temp;
            for(;i<str.Length;i++)
                str[i] = "";
            foreach (string temp in str)
                Console.Write(temp.Equals("")?"\"\" ":temp.ToString()+" ");
            Console.ReadKey();
        }
    }
}

看看
