I had created an HTML form using c# string builder using reference: https://stackoverflow.com/a/37757601/7961948
and in dotnet, we could submit this form using
Response.Write(formPostText);
But right now I am on DOTNET CORE 2.1 and DOTNET CORE does not support dotnet function so there is any another way to submit a form
sample code: working on dotnet version
var formPostText = @"<html><body><div>
<form method=""POST"" action=""OtherLogin.aspx"" name=""frm2Post"">
<input type=""hidden"" name=""field1"" value=""" + TextBox1.Text + @""" />
<input type=""hidden"" name=""field2"" value=""" + TextBox2.Text + @""" />
</form></div><script type=""text/javascript"">document.frm2Post.submit();</script></body></html>
";
Response.Write(formPostText);
Dotnet core support
var s = "some html / html form";
HttpContext.Response.WriteAsync(s.ToString());
Find refrence : https://gist.github.com/priore/7163408
Is there an equivalent to "HttpContext.Response.Write" in Asp.Net Core 2?
