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
