c# 4.0 - SendGrid incoming mail webhook - how to save the JSON format email data into my application folder in C# -

this regarding sendgrid incoming mail webhook, have referred url sendgrid incoming mail webhook - how secure endpoint, , got idea how go this, but, new mvc / webapi, give me controller method code snippet catch json format http post , save application folder.

this solution found after googling , slight modifications:

[httppost, httpget] [enablecors(origins: "*", headers: "*", methods: "*")] public async task post() {     if (request.content.ismimemultipartcontent("form-data"))         try         {             //to complete post in string use below line, not used here             string strcompletepost = await request.content.readasstringasync();              httpcontext context = httpcontext.current;             string strfrom = context.request.form.getvalues("from")[0];             string stremailtext = context.request.form.getvalues("email")[0];             string strsubject = context.request.form.getvalues("subject")[0];              //not useful guess, because return sendgrid ip             string strsenderip = context.request.form.getvalues("sender_ip")[0];         }         catch (exception ex)         {          } } 

i tried, retrieving values

string = context.request.params["to"]; 

but, value returned not consistent, i.e. of times returning null , returns actual value stored in it.

if have better solution, please let me know.

thank you
