TypeProvider.General

A prototype remake of FSharp.TypeProvider in CSharp

Project Nuget : dotnet add package Csharp.TypeProvider --version 0.1.0 (not working)

Usage :

[EmitType, Csv] private static string Grades { get; } = @"
""Last name"", ""First name"", ""Date Of Birth"", ""Subject1"", ""Subject2"", ""Subject3""
""Doe"",   ""John"",   1999-07-23, 23.0, 69.0, 42.0
""Doe"",   ""Jane"",   2001-02-16, 16.0, 48.0, 84.0
""Doe"",   ""John"",   2010-11-25, 25.0, 75.0, 168.0";

[EmitType, Json, FromUri] private static string TodoItem { get; } = "https://jsonplaceholder.typicode.com/todos/1";

[EmitType, Xml, FromUri] private static string PersonOfInterest { get; } = "D:\\Projects\\TypeProvider\\FileSample.xml";

private static void Main(string[] args)
{

    var todoItem_string = (new System.Net.WebClient()).DownloadString("https://jsonplaceholder.typicode.com/todos/23");
    var person_string = File.ReadAllText("D:\\Projects\\TypeProvider\\FileSample.xml");
    if (TodoItem_T.TryParse(todoItem_string, out var todoItem))
    {
        Console.WriteLine(todoItem);
    }

    if (PersonOfInterest_T.TryParse(person_string, out var person2))
    {
        Console.WriteLine(person2);
    }

    foreach(var student in Grades_T.ParseTable(Grades, hasHeader: true))
    {
        Console.WriteLine(student);
    }

}
