使用get方法获取页面的form内容

新建一个getform.html

    <html>
    <head>
    <title>Using Http Get Method</title>
    </head>
    <body>
    <form id="frm_get" action=" Receiving_Get_Form.aspx" target="_blank" method="GET" >
    <table>
    <tr>
    <td>First Name : </td> <td><input type="text" id="txtF_Name" name="F_name" /></td>
    </tr> <tr>
    <td>Last Name : </td> <td><input type=" text" id="txtL_name" name="L_name" /></td>
    </tr> <tr>
    <td>Email-Id : </td> <td><input type="text" id="txtE_mail" name="E_mail" /></td>
    </tr> <tr>
    <td>Password: </td> <td><input type="password" id="txtP_word" name="P_word"/> </td>
    </tr> <tr>
    <td><input type="submit" value="Submit" /></td>
    </tr>
    </table>
     </form> </body>
    </html>

新建一个Receiving_Get_Form.aspx页面

    <%@ page language="C#" AutoEventWireup="true" codeFile="Receiving_ Get_Form.aspx.cs" Inherits="Receiving_ Get_Form"% >
    <html>
    <head>
    <title>Data Received Here </title>
    </head>
    <body>
    <table border="1" cellpadding="6" cellspacing="3" >
    <tr>
    <td>First Name : </td> <td> <% Response.Write(Page.Request.QueryString["F_name"]); %> </td>
    </tr>
    <tr>
    <td>Last Name : </td> <td> <% Response.Write(Page.Request.QueryString["L_name"]); %> </td>
    </tr>
    <tr>
    <td>Email-Id : </td> <td> <% Response.Write(Page.Request.QueryString["E_mail"]); %> </td>
    </tr>
    <tr>
    <td>Password : </td> <td> <% Response.Write(Page.Request.QueryString["P_word"]); %> </td>
    </tr>
    </table>
    </body>
    </html>

GET - Requests data from a specified resource
An hyperlink or anchor tag that points to an action will ALWAYS be an HttpGet.
Data is submitted as a part of url.
Data is visible to the user as it posts as query string.
It is not secure but fast and quick.
It use Stack method for passing form variable.
Data is limited to max length of query string.
It is good when you want user to bookmark page.

使用post获取表单内容

    </head>
    <body>
    <form id="frm_post" action=" Receiving_Post_Form.aspx" target="_blank" method=" POST" >
    <table>
    <tr>
     <td>First Name : </td> <td><input type="text" id="txtF_Name" name="F_name" /></td>
    </tr> <tr>
    <td>Last Name : </td> <td><input type=" text" id="txtL_name" name="L_name" /></td>
    </tr> <tr>
     <td>Email-Id : </td> <td><input type="text" id="txtE_mail" name="E_mail" /></td>
    </tr> <tr>
     <td>Password: </td> <td><input type="password" id="txtP_word" name="P_word"/> </td>
    </tr> <tr>
    <td><input type="submit" value="Submit" /></td>
    </tr>
    </table>
     </form> </body>
    </html>

    <%@ page language="C#" AutoEventWireup="true" codeFile="Receiving_Post_Form.aspx.cs" Inherits=" Receiving_Post_Form"% >
    <html>
    <head>
    <title>Data Received Here </title>
    </head>
    <body>
    <table border="1" cellpadding="6" cellspacing="3" >
    <tr>
    <td>First Name : </td> <td> <% Response.Write(Page.Request.Form["F_name"]); %> </td>
    </tr>
    <tr>
    <td>Last Name : </td> <td> <% Response.Write(Page.Request.Form["L_name"]); %> </td>
    </tr>
    <tr>
    <td>Email-Id : </td> <td> <% Response.Write(Page.Request. Form["E_mail"]); %> </td>
    </tr>
    <tr>
