[英]Bind datagrid using third party API datasource
I am using C# 4.5
. 我正在使用
C# 4.5
。 I have created a windows application. 我创建了一个Windows应用程序。
As per the project requirement, I need to bind a third-party api response that returns array of json
objects into a datagrid
. 根据项目要求,我需要绑定第三方api响应,该响应将
json
对象数组json
到datagrid
。
I've fetched data using RestClient
and have converted them to object using JDynamic
package as 我使用
RestClient
获取数据,并使用JDynamic
包将它们转换为对象
IRestResponse response = client.Execute(request);
dynamic result = new JDynamic(response.Content);
Is there any technique I may bind this array of objects as a datasource of gridview? 是否有任何技术可以将这个对象数组绑定为gridview的数据源?
Also, what if I need to display only certain columns? 另外,如果我只需要显示某些列呢?
Edit: 编辑:
The JSON response is something like: JSON响应类似于:

I have created a new class for it as below: 我为它创建了一个新类,如下所示:
namespace DemoAutoLogin
{
public class patient
{
public int id { get; set; }
public string username { get; set; }
public string first_name { get; set; }
public string middle_name { get; set; }
public string last_name { get; set; }
public string gender { get; set; }
public string addr1 { get; set; }
public string addr2 { get; set; }
public string state { get; set; }
public string city { get; set; }
public string country { get; set; }
public string post_code { get; set; }
public string email_id { get; set; }
public string email_id_alt { get; set; }
public string phone1 { get; set; }
public string phone2 { get; set; }
public string photo { get; set; }
public List<Population> populations { get; set; }
}
public class Population
{
public int id { get; set; }
public string population_name { get; set; }
}
}
Now, what can I do to display the JSON records in grid view? 现在,我该怎么做才能在网格视图中显示JSON记录?
You then simply can deserialize from result to the IEnumerable<patient>
. 然后,您可以简单地从结果反序列化到
IEnumerable<patient>
。 Use Json.NET for this. 使用Json.NET。 the
IEnumerable<patient>
you can bind to the grid. IEnumerable<patient>
可以绑定到网格。
public void BindMyData()
{
IEnumerable<patient> patients = JsonConvert.DeserializeObject<IEnumerable<patient>>(resultAsJson);
datagrid.DataSource = patients;
}
Should work this way.. 应该这样工作..
if you don't have a poco: 如果你没有poco:
public void BindMyData()
{
IEnumerable<Dictionary<string, object>> patients = JsonConvert.DeserializeObject<List<Dictionary<string, object>>>(resultAsString);
// if this works, i'm not sure:
datagrid.DataSource = patients;
}
if you can't bin the IEnumerable<Dictionary<string, object>>
to the grid, you maybe could bind a DataTable. 如果你不能将
IEnumerable<Dictionary<string, object>>
绑定到网格,你可能可以绑定一个DataTable。 Add this ToDataTable
extension: 添加此
ToDataTable
扩展:
public static class Exts
{
public static DataTable ToDataTable(this IEnumerable<Dictionary<string, object>> list)
{
DataTable result = new DataTable();
if (!list.Any())
return result;
var columnNames = list.SelectMany(dict => dict.Keys).Distinct();
result.Columns.AddRange(columnNames.Select(c => new DataColumn(c)).ToArray());
foreach (var item in list)
{
var row = result.NewRow();
foreach (var key in item.Keys)
row[key] = item[key];
result.Rows.Add(row);
}
return result;
}
}
and then bind it this way: 然后以这种方式绑定它:
public void BindMyData()
{
IEnumerable<Dictionary<string, object>> patients = JsonConvert.DeserializeObject<List<Dictionary<string, object>>>(resultAsString);
datagrid.DataSource = patients.ToDataTable();
}
