entity framework - List Data from DB using POST method in C# Web API EF -

i working on project , 1 of requirements able list value stories without using method.

i have controller code here:

// post api/valuestories [responsetype(typeof(valuestory))] public async task<valuestory> postvaluestory([frombody] string value) {     valuestory valuestory = await db.valuestories.findasync();      var valuestoryname = (from vs in db.valuestories                           vs.id == valuestory.id                           select vs).tolist();      list<valuestory> vs1 = new list<valuestory>();     foreach (var v in valuestoryname)     {         vs1.add(new valuestory()         {             id = v.id,             valuestoryname = v.valuestoryname,             organization = v.organization,             industry = v.industry,             location = v.location,             annualrevenue = v.annualrevenue,             createddate = v.createddate,             modifieddate = v.modifieddate,             mutualactionplan = v.mutualactionplan,             currency = v.currency,             vsid = v.vsid         });     }     return valuestory;  } 

and code in model:

namespace webservicesapi.models {     public class valuestory     {         [key]         public int vsid { get; set; }         [required]         public string valuestoryname { get; set; }         [required]         public string organization { get; set; }         [required]         public int industry { get; set; }         [required]         public string location { get; set; }         [required]         public string currency { get; set; }         [required]         public double annualrevenue { get; set; }         public datetime createddate { get; set; }         public datetime modifieddate { get; set; }         public string mutualactionplan { get; set; }          // foreign key         public string id { get; set; }         // navigation property         public virtual applicationuser user { get; set; }       }  } 

i tried test using postman supplying id on body getting error [link]https://ibb.co/gn5mz5

i started learning c# 2 months ago , still trying myself familiar it.

appreciate here.

i managed working changing controller code to:

// post api/uservaluestories [responsetype(typeof(valuestory))] [route("api/uservaluestories")] [httppost] public list<valuestory> uservaluestories([frombody] valuestory valuestory) //public void uservaluestories([frombody] valuestory id) {     var valuestoryname = (from vs in db.valuestories                           vs.id == valuestory.id                           select vs).tolist();      list<valuestory> vs1 = new list<valuestory>();     foreach (var v in valuestoryname)     {         vs1.add(new valuestory()         {             id = v.id,             valuestoryname = v.valuestoryname,             organization = v.organization,             industry = v.industry,             location = v.location,             annualrevenue = v.annualrevenue,             createddate = v.createddate,             modifieddate = v.modifieddate,             mutualactionplan = v.mutualactionplan,             currency = v.currency,             vsid = v.vsid         });     }     return vs1.tolist();  }
