아래의 클래스를 추가 한 뒤

public class RemotePost

{

private System.Collections.Specialized.NameValueCollection Inputs

= new System.Collections.Specialized.NameValueCollection();

public string Url = "";

public string Method = "post";

public string FormName = "form1";

public void Add(string name, string value)

{

Inputs.Add(name, value);

}

public void Post()

{

System.Web.HttpContext.Current.Response.Clear();

System.Web.HttpContext.Current.Response.Write("<html><head>");

System.Web.HttpContext.Current.Response.Write(string.Format("</head><body onload=\"document.{0}.submit()\">", FormName));

System.Web.HttpContext.Current.Response.Write(string.Format("<form name=\"{0}\" method=\"{1}\" action=\"{2}\" >",

FormName, Method, Url));

for (int i = 0; i < Inputs.Keys.Count; i++)

{

System.Web.HttpContext.Current.Response.Write(string.Format("<input name=\"{0}\" type=\"hidden\" value=\"{1}\">", Inputs.Keys[i], Inputs[Inputs.Keys[i]]));

}

System.Web.HttpContext.Current.Response.Write("</form>");

System.Web.HttpContext.Current.Response.Write("</body></html>");

System.Web.HttpContext.Current.Response.End();

}

}

아래와 같이 사용한다

string URI = "http://" + Request.Url.Host + "/url";

RemotePost r = new RemotePost();

r.Url = URI;

r.Add("test", "value1test");

r.Post();
