Now Please tell me how to deserilise and show it in datagridview!!!

推荐答案

所以这是非常简单的：

So this is pretty straight forward:

1. 声明一个反序列化的类。


2. 获取Json.NET NuGet软件包。 li>
   
3. 反序列化字符串。


4. 绑定 DataGridView 。

1. Declare a class to deserialize into.
2. Grab the Json.NET NuGet Package.
3. Deserialize the string.
4. Bind the DataGridView.

声明一个类来反序列化为

Declare a class to deserialize into

public class JsonResult
{
    public int testId { get; set; }
    public string testName { get; set; }
    public int minScore { get; set; }
    public int score { get; set; }
    public DateTime date { get; set; }
    public string status { get; set; }
}

获取Json.NET NuGet软件包

从这里 Json.NET NuGet软件包/6.0.3rel =noreferrer> http://www.nuget.org/packages/Newtonsoft.Json/6.0.3 。

Grab the Json.NET NuGet Package

Pull the Json.NET NuGet Package in from here http://www.nuget.org/packages/Newtonsoft.Json/6.0.3.

var result = JsonConvert.DeserializeObject<List<JsonResult>>(input);

绑定 DataGridView

Bind the DataGridView

dataGridView.DataSource = result;

注意：这是绑定到网格的最原始的方式。还有更多的选择可以利用。需要注意的是，关闭 AutoGenerateColumns 并定义自己的列;设计师驱动的工作，所以它不会影响我提供的代码。

NOTE: this is the most primitive way of binding to the grid. There are many more options that you can leverage. One that comes to mind is, turning off AutoGenerateColumns and defining your own columns; designer-driven work so it wouldn't affect the code I've provided.
