推荐答案

我发现如何订购IE打开一个网页，发送一些POST数据。

• 添加一个名为COM引用的 Microsoft Internet Explorer中控件的该项目。

然后创建后的字符串与现场和它的价值分开通过&安培; ，然后将其转换字符串到字节数组。

Then create the post string with the field and its value separated by &, and then convert that string into a byte array.

而在刚刚结束只好请求IE导航到网址，和也发送POST数据转换成字节数组，然后添加相同的标题，它的附加当我们提交表单。

And in the end just had to request IE to Navigate to the url, and also send the Post Data converted into a byte array, and then add the same Header that its added when we submit a form.

这里所说：

using SHDocVw; // Don't forget

InternetExplorer IEControl = new InternetExplorer();
IWebBrowserApp IE = (IWebBrowserApp)IEControl;
IE.Visible = true;

// Convert the string into a byte array
ASCIIEncoding Encode = new ASCIIEncoding();
byte[] post = Encode.GetBytes("username=fabio&password=123");

// The destination url
string url = "http://example.com/check.php";

// The same Header that its sent when you submit a form.
string PostHeaders = "Content-Type: application/x-www-form-urlencoded";

IE.Navigate(url, null, null, post, PostHeaders);

注意：

要试试，如果这个工程。不要忘记，你的服务器端页面必须的写/回声的命名邮政领域：用户名和密码。

To try if this works. Don't forget that your server side page would have to write/echo the Post fields named: username and password.

的 PHP代码示例：的

<?php
echo $_POST['username'];
echo " ";
echo $_POST['password'];
?>

的 ASP代码示例：的

<%
response.write(Request.Form("username"))
response.write(" " & Request.Form("password"))
