使用数组将值分配给列表框

Question

我正在尝试使用数组将电影标题分配给列表框。他们在下拉列表中选择电影，然后使用C＃和aspx

显示在列表框中（这不起作用）

  protected void addToCartImageButton_Click(object sender, ImageClickEventArgs e)
  {

    string [] movieNameArray = new string [10];

    movieNameArray[0] = "The Advengers";
    movieNameArray[1] = "Titanic";
    movieNameArray[2] = "Frozen";
    movieNameArray[3] = "Boy";
    movieNameArray[4] = "Grown Ups";
    movieNameArray[5] = "Coach Carter";
    movieNameArray[6] = "More than a game";
    movieNameArray[7] = "Harry Potter";
    movieNameArray[8] = "Avatar";
    movieNameArray[9] = "Titanic";



    cartListBox.Items.Add(movieNameArray.ToString());
    DropDownList3.Items.Add(movieNameArray.ToString());

}

Answer 1

您可以将下拉列表绑定到数组。即而不是

DropDownList3.Items.Add(movieNameArray.ToString());

使用

DropDownList3.DataSource = movieNameArray;
DropDownList3.DataBind();
