我正在尝试将List<AreaField>
绑定到转发器。我已使用ToArray()
方法将列表转换为数组,现在有一个AreaField[]
数组
这是我的班级层次结构
public class AreaFields
{
public List<Fields> Fields { set; get; }
}
public class Fields
{
public string Name { set; get; }
public string Value {set; get; }
}
在aspx中,我想将它绑定一个转发器(类似这样)
DataBinder.Eval(Container.DataItem, "MyAreaFieldName1")
MyAreaFieldName1是AreaFieldItem类中Name属性的值。

令人惊讶的简单......
代码背后:
// Here's your object that you'll create a list of
private class Products
{
public string ProductName { get; set; }
public string ProductDescription { get; set; }
public string ProductPrice { get; set; }
}
// Here you pass in the List of Products
private void BindItemsInCart(List<Products> ListOfSelectedProducts)
{
// The the LIST as the DataSource
this.rptItemsInCart.DataSource = ListOfSelectedProducts;
// Then bind the repeater
// The public properties become the columns of your repeater
this.rptItemsInCart.DataBind();
}
ASPX代码:
<asp:Repeater ID="rptItemsInCart" runat="server">
<HeaderTemplate>
<table>
<thead>
<tr>
<th>Product Name</th>
<th>Product Description</th>
<th>Product Price</th>
</tr>
</thead>
<tbody>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%# Eval("ProductName") %></td>
<td><%# Eval("ProductDescription")%></td>
<td><%# Eval("ProductPrice")%></td>
</tr>
</ItemTemplate>
<FooterTemplate>
</tbody>
</table>
</FooterTemplate>
</asp:Repeater>
我希望这有帮助!

您可能想要创建一个subRepeater。
<asp:Repeater ID="SubRepeater" runat="server" DataSource='<%# Eval("Fields") %>'>
<ItemTemplate>
<span><%# Eval("Name") %></span>
</ItemTemplate>
</asp:Repeater>
您还可以投射字段
<%# ((ArrayFields)Container.DataItem).Fields[0].Name %>
最后,您可以执行一些CSV功能,并使用函数
写出您的字段<%# GetAsCsv(((ArrayFields)Container.DataItem).Fields) %>
public string GetAsCsv(IEnumerable<Fields> fields)
{
var builder = new StringBuilder();
foreach(var f in fields)
{
builder.Append(f);
builder.Append(",");
}
builder.Remove(builder.Length - 1);
return builder.ToString();
}

代码背后:
public class Friends
{
public string ID { get; set; }
public string Name { get; set; }
public string Image { get; set; }
}
protected void Page_Load(object sender, EventArgs e)
{
List <Friends> friendsList = new List<Friends>();
foreach (var friend in friendz)
{
friendsList.Add(
new Friends { ID = friend.id, Name = friend.name }
);
}
this.rptFriends.DataSource = friendsList;
this.rptFriends.DataBind();
}
.aspx Page
<asp:Repeater ID="rptFriends" runat="server">
<HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0">
<thead>
<tr>
<th>ID</th>
<th>Name</th>
</tr>
</thead>
<tbody>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%# Eval("ID") %></td>
<td><%# Eval("Name") %></td>
</tr>
</ItemTemplate>
<FooterTemplate>
</tbody>
</table>
</FooterTemplate>
</asp:Repeater>

您应该使用ToList()方法。 (不要忘记System.Linq命名空间)
例如:
IList<Model> models = Builder<Model>.CreateListOfSize(10).Build();
List<Model> lstMOdels = models.ToList();
