显示WCF Rest服务数据到gridview [英] display WCF Rest service data to gridview

问题描述

你好，

我有一个Wcf rest服务，该服务返回list< student>.但是问题是，当我使用该服务时，数据将在byte[]中返回.

如何将其转换为list< student>这样我就可以将其绑定到Gridview.

以下代码可以正常工作.

Hello,

I have one Wcf rest service which returns list<student>. But the problem is that when I consume the service, data is returned in byte[].

How can I convert it to list<student> so that I can bind it to Gridview.

Following code works fine.

byte[] data = proxy.DownloadData("http://localhost:6236/Service1.svc/GetData");
       Stream stream = new MemoryStream(data);
       DataContractSerializer obj = new DataContractSerializer(typeof(string));
       string result = obj.ReadObject(stream).ToString();
       TextBox1.Text = result;

我需要做些什么改变才能解决我的问题.

谢谢，
Dhaval

What changes do i need to do to solve my problem.

推荐答案

理想情况下，您的REST服务应以XML/JSON格式返回数据.

从REST服务以XML格式获取数据后，可以使用DataSet.ReadXml填充数据集.

http://msdn.microsoft.com/en-us/library/system. data.dataset.readxml.aspx

然后将您的DataSet绑定到GridView.

Ideally your REST service should return Data in a XML/JSON format.

Once you get your Data from your REST service in XML format, you may use DataSet.ReadXml to populate your DataSet.

http://msdn.microsoft.com/en-us/library/system.data.dataset.readxml.aspx

And then bind your DataSet to your GridView.

myGrid.DataSource = myDataset;
myGrid.DataBind();

报价:

[WebGet(UriTemplate ="/GetDataList"，RequestFormat = WebMessageFormat.Json，ResponseFormat = WebMessageFormat.Json)]列表<人> GetDataList();

[WebGet(UriTemplate = "/GetDataList", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] List<person> GetDataList();

如果您以JSON格式从REST服务返回您的详细信息，请参考以下链接进行反序列化.

In case if you return your details from your REST Service in JSON format, then refer below link for it''s deserialization.

如果可以的话，请提供给我任何示例.

can you provide me any example if you have available.
