What is the proper way to pass parameters into Asp.Net core MVC controllers. For example, I have a controller with the following signature:

[HttpPost]
public async Task<ActionResult<Input>> PostInput(Input input, string OutputPath)

Note: Input is just some class I made. How do I call this function from my react application and pass in the parameters.

Thank you in advance!

You cannot pass two parameter together either in [FromBody] neither in [FromForm] because its not allowed to pass more than one parameter within one action specially for [FromBody] context . So either you have to move the OutputPath into the class or pass the class property as method argument. You could get more details on the

Valid Signature Format: 2 With Class Fashion

    [HttpPost]
    public async Task<ActionResult> PostInput(Input input)
    {
        return Ok();
    }

Model Should Be:

public class Input
    {
        public string InputPropertyName { get; set; }    
        public string OutputPath { get; set; }    
    }

Output: 2
