NET Core 5 : How to pass string list as a parameter?-CodePudding

My app is: NET Core 5 Web service. I need to pass to HTTP PUT method a csv file. The csv is like string1, string2, string3.

As one way I see: upload the csv file and then parse it to corresponding class. But what else way? How to pass the string list in RESTful API?

CodePudding user response：

Assuming your string list is longer than an URL should be, you define a body:

public class Model 
{
    public List<string> StringList { get; set; }
}

Then in your controller, you chose a HTTP method that accepts a body (PUT/POST most likely):

[HttpPost]
public IActionResult YourMethod([FromBody] Model model)
{
    // and here, you can access model.StringList
}

Please note that an XLS or even CSV file is not just a string list. You would be better served by uploading the file and using an actual parser package that can handle that file format.
