Upload a file using WebApi

I have a file which is located at "D:\\NCDoc98.docx" and I want to pass that as parameter in a WebAPI

 

[HttpPost]

public async Task UploadFile(string file)

{

//code here to upload directly to my IIS folder

}

 

I saw tutorial using IFormFile which needs I GUI. all want is just to pass the path of the file and it will directly upload the file to the current folder of my asp.net core files..
