使用 datagridview 将列表序列化为现有的 .Json 文件

Question

我有一个反序列化的 json 文件直接输出到 DGV，并且在 DGV 中对最终用户可见。当他们完成使用软件并关闭时，我想将更新的DGV 序列化到我的 json 文件中。

当我反序列化这个json文件时，代码如下：

代码

    var v = JsonConvert.DeserializeObject<ToolJson> 
    (File.ReadAllText(@"\testLibrary.json"));

        //set DGV source to our datums 
        toolDataGridView.DataSource = v.Datums.Cast<IInteresting> 
        ().ToList();

当表单关闭时，我想将 DGV 读回我的 json 文件，格式与它已经完全相同。下面是 json 文件的 sn-p。我对 DGV 所做的只是跟踪数量、最后使用的员工以及是否需要退回工具。基本上是 json 文件的 5 个新条目。顶级属性。

清除随附的文本，我想我了解困难所在，确实它是我们需要使用的一种奇异数据类型，除非 json 中只有一个列表，在这种情况下，您可以简单地将表添加到命名数据集“工具" 并对其进行序列化，我已将两者都包含在内

public partial class frmWithGrid : Form
{                 
    public frmWithGrid()
    {
        InitializeComponent();

        string myDynamicJSON = "Imagine your testLibraryJson loaded here or later but before next line";
        DataTable convertedToTableToolData = ConvertToTableToolData(myDynamicJSON);

        dataGridView1.DataSource = convertedToTableToolData;
        //dataGridView1.DataMember = we're not storing it in a dataset so we can ignore this one
        dataGridView1.AutoGenerateColumns = true;   
        
        //TODO: Add bla bla to setup UI of cause, suppose you're able to navigate rows etc.
    }

    DataTable ConvertToTableToolData(string jsonSource)
    {
        //TODO: Insert own convertion code here, which seems to be in place
        return new DataTable(); // instead of this
    }

    private void btnUserIsDone_Click(object sender, EventArgs e)
    {
        //Obviously this shouldn't be directly in an event handler

        //Either you have many lists
        dynamic x = new ExpandoObject();
        var editedTable = (DataTable)dataGridView1.DataSource;
        //Will ignore that your OrderQty maybe wasn't originally part of data structure, because it may have been
        //and it doesn't change anything with the principle, and adds needless complexity
        var propertiesDictionary = (IDictionary<string, object>)x;
        propertiesDictionary.Add("Tool", editedTable);

        //TODO: Add other sets to json if applicable

        string serialized = Newtonsoft.Json.JsonConvert.SerializeObject(x);



        //or just one
        var ds = new DataSet("Tool");
        ds.Tables.Add(editedTable.Clone());
        serialized = Newtonsoft.Json.JsonConvert.SerializeObject(ds);
    }
}
