推荐答案

有一个名为 Newtonsoft JSON.Net 的库，您可以使用它来轻松地序列化和串行化JSON字符串来回到C＃/ VB.NET对象。看一下这篇文章，例如：将JSON转换为DataTable使用C＃或VB.Net - blakepell.com [ ^ ]



想要将JSON文件流式化为字符串，然后将其转换为将JSON字符串转换为对象。该对象可以是一个集合，数组或数据表，您可以在其中用作GridView的数据源。



修改底层JSON文件是另一个故事，因为您需要将GridView中的数据解析回JSON对象或JArray，进行修改，然后将更改写回文件。这是一个例子： https：//www.c -sharpcorner.com/article/crud-operation-with-json-file-data-in-c-sharp/ [ ^ ]



上面的例子是用C＃编写的。如果您在解释代码时遇到困难，可以使用此在线免费转换工具将C＃转换为VB.NET： Code Converter C＃to VB and VB到C＃ - Telerik [ ^ ]

There's a library called Newtonsoft JSON.Net that you can use to easily serialize and serialize JSON string back and forth to C#/VB.NET object. Take a look at this article for example: Convert JSON to a DataTable with C# or VB.Net - blakepell.com[^]

The idea if to stream your JSON file to a string, and then convert that JSON string into an object. This object can be a collection, array or datatable in which you can use as data source for your GridView.

Modifying the underlying JSON file is another story as you need to parse the data from your GridView back to a JSON object or JArray, do the modification and then write the changes back to a file. Here's one example: https://www.c-sharpcorner.com/article/crud-operation-with-json-file-data-in-c-sharp/[^]

The example above is written in C#. If you are having a hard time interpreting the code, you can use this online free converter tool to translate C# to VB.NET: Code Converter C# to VB and VB to C# – Telerik[^]
