Asp.net中的页面跳转及post数据

 /// <summary>
 /// This method prepares an Html form which holds all data
 /// in hidden field in the addetion to form submitting script.
 /// </summary>
 /// <param name="url">The destination Url to which the post and redirection
 /// will occur, the Url can be in the same App or ouside the App.</param>
 /// <param name="data">A collection of data that
 /// will be posted to the destination Url.</param>
 /// <returns>Returns a string representation of the Posting form.</returns>
 /// <Author>Samer Abu Rabie</Author>

 private static String PreparePOSTForm(string url, NameValueCollection data)
 {
     //Set a name for the form
     string formID = "PostForm";
     //Build the form using the specified data to be posted.
     StringBuilder strForm = new StringBuilder();
     strForm.Append("<form id=\"" + formID + "\" name=\"" +
                    formID + "\" action=\"" + url +
                    "\" method=\"POST\">");

     foreach (string key in data)
     {
         strForm.Append("<input type=\"hidden\" name=\"" + key +
                        "\" value=\"" + data[key] + "\">");
     }

     strForm.Append("</form>");
     //Build the JavaScript which will do the Posting operation.
     StringBuilder strScript = new StringBuilder();
     strScript.Append("<script language="'javascript'">");
     strScript.Append("var v" + formID + " = document." +
                      formID + ";");
     strScript.Append("v" + formID + ".submit();");
     strScript.Append("</script>");
     //Return the form and the script concatenated.
     //(The order is important, Form then JavaScript)
     return strForm.ToString() + strScript.ToString();
 }

对于每一个想提交的数据， 我们创建了一个隐藏域来保存它的值，我们添加了必要的脚本，通过 vPostForm.submit() 来使表单完成自动提交操作。

 /// <summary>
 /// POST data and Redirect to the specified url using the specified page.
 /// </summary>
 /// <param name="page">The page which will be the referrer page.</param>
 /// <param name="destinationUrl">The destination Url to which
 /// the post and redirection is occuring.</param>
 /// <param name="data">The data should be posted.</param>
 /// <Author>Samer Abu Rabie</Author>

 public static void RedirectAndPOST(Page page, string destinationUrl,
                                    NameValueCollection data)
 {
 //Prepare the Posting form
 string strForm = PreparePOSTForm(destinationUrl, data);
 //Add a literal control the specified page holding
 //the Post Form, this is to submit the Posting form with the request.
 page.Controls.Add(new LiteralControl(strForm));
 }

 NameValueCollection data = new NameValueCollection();
 data.Add("v1", "val1");
 data.Add("v2", "val2");
 HttpHelper.RedirectAndPOST(this.Page, "http://DestUrl/Default.aspx", data);

同样的这种思路还可以在js中运用
