学用 ASP.Net 之 System.Collections.Specialized.StringCollection 类

StringCollection 是专用于储存字符串的集合, 相当于字符串的动态数组.

---

主要成员:

---

/* 属性 */

Count;      //



/* 方法 */

Add();      //添加字符串

AddRange(); //添加字符串数组

Clear();    //清空

Contains(); //是否存在

CopyTo();   //复制到字符串数组

IndexOf();  //取索引, 无则 -1

Insert();   //插入

Remove();   //删除指定元素

RemoveAt(); //根据索引删除

---

简单测试:

---

protected void Button1_Click(object sender, EventArgs e)

{

    StringCollection sc = new StringCollection();



    sc.Add("AAA");

    sc.Add("BBB");



    sc.AddRange(new string[3] {"one", "two", "three"});



    sc.Insert(1, "111");

    sc.Insert(0, "000");



    string str = "";

    for (int i = 0; i < sc.Count; i++) { str += sc[i] + "; "; }



    TextBox1.Text = str; //000; AAA; 111; BBB; one; two; three; 

}



protected void Button2_Click(object sender, EventArgs e)

{

    StringCollection sc = new StringCollection();

    string[] strArr = "aaa,bbb,ccc,ddd,eee,fff".Split(',');

    sc.AddRange(strArr);



    sc.RemoveAt(2);

    sc.Remove("ddd");



    string str = "";

    foreach (string s in sc) { str += s + "; "; }

    TextBox1.Text = str; //aaa; bbb; eee; fff; 

}
