绑定类型结构的一个泛型列表到中继器 [英] Binding a Generic List of type struct to a Repeater

问题描述

我已经有点试图绑定一个泛型列表到中继器的问题。在通用列表中使用的类型实际上是一个结构。

I've had a bit of a problem trying to bind a generic list to a repeater. The type used in the generic list is actually a struct.

我已经建立了下面一个基本的例子：

I've built a basic example below:

struct Fruit
{
    public string FruitName;
    public string Price;    // string for simplicity.
}


protected void Page_Load(object sender, EventArgs e)
{

    List<Fruit> FruitList = new List<Fruit>();

    // create an apple and orange Fruit struct and add to List<Fruit>.
    Fruit apple = new Fruit();
    apple.FruitName = "Apple";
    apple.Price = "3.99";
    FruitList.Add(apple);

    Fruit orange = new Fruit();
    orange.FruitName = "Orange";
    orange.Price = "5.99";
    FruitList.Add(orange);


    // now bind the List to the repeater:
    repFruit.DataSource = FruitList;
    repFruit.DataBind();

}

我有一个简单的结构，以水果模型，我们有这两种性能FruitName和价格。我通过创建类型的空泛型列表'FruitList启动。

I have a simple struct to model Fruit, we have two properties which are FruitName and Price. I start by creating an empty generic list of type 'FruitList'.

然后我创建一个使用结构（苹果和橘子）两种水果。这些水果然后加入到列表中。

I then create two fruits using the struct (apple and orange). These fruits are then added to the list.

最后，我绑定泛型列表的直放站的DataSource属性...

Finally, I bind the generic list to the DataSource property of the repeater...

的标记看起来是这样的：

The markup looks like this:

<asp:repeater ID="repFruit" runat="server">
<ItemTemplate>
    Name: <%# Eval("FruitName") %><br />
    Price: <%# Eval("Price") %><br />
    <hr />
</ItemTemplate>

我希望看到的水果名称和价格印在屏幕上，由一个水平线分隔。

I expect to see the fruit name and price printed on the screen, separated by a horizontal rule.

目前我正在与实际绑定错误...

At the moment I am getting an error relating to actual binding...

**Exception Details: System.Web.HttpException: DataBinding: '_Default+Fruit' does not contain a property with the name 'FruitName'.**

我甚至不知道这是否可以工作？任何想法？

I'm not even sure if this can work? Any Ideas?

推荐答案

您需要将您的公共领域变成一个公共属性。

You need to change your public field into a public property.

更改此：公共字符串FruitName;

要：

public string FruitName { get; set; }

否则你可以做fruitName私人和包括公共财产吧。

Otherwise you could make fruitName private and include a public property for it.

private string fruitName;

public string FruitName { get { return fruitName; } set { fruitName = value; } }
