find the creation date of a json file in csharp

You can use the FileInfo class in System.IO to get the metadata of the file, including the creation date. Here's an example code snippet:

main.cs
using System;
using System.IO;

class Program
{
    static void Main(string[] args)
    {
        string filePath = "path/to/your/json/file.json";
        
        FileInfo fileInfo = new FileInfo(filePath);
        DateTime creationDate = fileInfo.CreationTime;

        Console.WriteLine($"The creation date of {filePath} is {creationDate}");
    }
}

In this code snippet, the filePath variable should be replaced with the actual path to your JSON file.

The FileInfo class is used to get the metadata of the file. And the CreationTime property of the FileInfo instance is used to get the creation date of the file. This value is stored in a DateTime variable, which can be used to print the creation date to the console.
