Pass a JSON string as a command line argument

Question

I am trying to pass a json string to a C#-Program using Commandline.

The JSON-String looks like this:

{
    \"config\": {
        \"script\": {

Try to save the JSON object into a file, and pass the file as the argument to your application.

@Wildcard27 : This is an actual use case in order to create Windows Tasks which was used for the faculty degree app. The JSON was just a simple serialization of a DTO that I was using.

When you serialize the JSON, just save it into a blank file, giving it a proper name so that is unique.

    private string CreateTaskConfigurationFile(string taskName, EquipmentEventExtended eventData, string host)
        {
            List changes = new List
            {
                new Change(MailConstants.EventName,eventData.EventName),
                new Change(MailConstants.Deadline, eventData.DateTo.Value.ToShortDateString()),
                new Change(MailConstants.EventDetails, eventData.EventDetails),
                new Change(MailConstants.Link,$"{host}/Inventory/Details/{eventData.InventoryId}")
            };

            MailTaskModel mtm = new MailTaskModel
            {
                Body = MailConstants.UpdateTemplate(MailConstants.TaskMailTemplate, changes),
                Subject = "[Reminder] Upcoming Event needs your attention",
                ToAddress = "abcdef@gmail.com",
                IsHtml = true
            };
            var fileName = string.Format(@"E:\{0}.json", taskName);
            using (StreamWriter file = File.CreateText(fileName))
            {
                JsonSerializer js = new JsonSerializer();
                js.Serialize(file, mtm);
            }
            return fileName;
        }

Then you provide the file path as an argument to the console application:

static void Main(string[] args)
        {
            var configFilePath = args[0];
            var mailConfig = LoadConfigurationFile(configFilePath);
            MailManager manager = new MailManager(mailConfig.ToAddress, mailConfig.FromAddress,mailConfig.Subject, mailConfig.Body,mailConfig.IsHtml);
            manager.SendMail();
        }
        private static MailTaskModel LoadConfigurationFile(string configurationFilePath)
        {
            MailTaskModel mailConfig;
            using(var sr = new StreamReader(configurationFilePath))
            {
                string json = sr.ReadToEnd();
                mailConfig = JsonConvert.DeserializeObject(json);
            }
            return mailConfig;
        }

You can then use something like

ConsoleApplication.exe -yourFilePath

I've removed noisy check-ups for nulls and all that so that it's more clear.
