Form.Post 中的 NameValueCollection 显示 FIELDS 和 VALUES

Question

I need to grab all the FIELD and VALUES from a POST.

I have the follow which only return the FIELDs but no Values.

NameValueCollection authForm = Request.Form;
String[] a = authForm.AllKeys;

for (i = 0; i < a.Length; i++)
{
    frm += ("Form: " + a[i] + " : " + "<br>");
}

Response.Write(frm);

What can I add this the frm string to show the VALUES?

UPDATE:

I used the initial code of

    NameValueCollection authForm = Request.Form;
    foreach (string key in authForm.AllKeys)
    {
        frm += ("Key: " + key + ", Value: " + authForm[key] + "<br/>");
    }

which worked great. I will try the new variation below.

Answer 1

NameValueCollection authForm = Request.Form;
StringBuilder sb = new StringBuilder();
foreach (string key in authForm.AllKeys)
{
    sb.AppendFormat(
        "Key: {0}, Value: {1}<br/>", 
        HttpUtility.HtmlEncode(key), 
        HttpUtility.HtmlEncode(authForm[key])
    );
}
Response.Write(sb.ToString());
