不显示属性列表数据

网关.cs页面 

public class gatewayConnectionPropertyData
{
public string url { get; set; }
public int type { get; set; }
public string service_desc { get; set; }
}
protected void btnAddEdit_Click(object sender, EventArgs e) 
{
gatewayConnectionPropertyData proposal = new gatewayConnectionPropertyData();
proposal.url = "/testproposal.xml";
proposal.type = 13;
proposal.service_desc = "proposal";
gatewayConnectionPropertyData utility = new gatewayConnectionPropertyData();
proposal.url = "/testUtulity.xml";
proposal.type = 12;
proposal.service_desc = "utility";
gatewayConnectionPropertyData intelligence = new gatewayConnectionPropertyData();
proposal.url = "/testinteligence.xml";
proposal.type = 53;
proposal.service_desc = "intelligence";

List<gatewayConnectionPropertyData> mydataList = new List<gatewayConnectionPropertyData>(); 
gatewayConnectionPropertyDataList.Add(proposal); 
gatewayConnectionPropertyDataList.Add(utility); 
gatewayConnectionPropertyDataList.Add(intelligence); 
}

mydataList 总是计数 3，但只出现 last 添加的项目，我看不到所有数据，我错过了我需要更改的内容。如果有任何意见，我可以申请更好的解决方案，以创建属性列表模型。

谢谢。

不显示属性列表数据

首先，

您要在gatewayConnectionPropertyDataList中添加项目（我不确定它是什么），但是如果您期望mydataList中的数据，则只需要添加此变量。此外，您可以像这样使用collection initializers：-

List<gatewayConnectionPropertyData> mydataList = 
                                new List<gatewayConnectionPropertyData>
{
  new gatewayConnectionPropertyData { url = "/testproposal.xml", type = 13, 
                                             service_desc = "proposal" },
  new gatewayConnectionPropertyData { url = "/testUtulity.xml", type = 12, 
                                             service_desc = "utility" },
  new gatewayConnectionPropertyData { url = "/testinteligence.xml", type = 53,
                                             service_desc = "intelligence" },
};
