你最好看一下WebRequest班级(System.Net).

您需要查看POST方法以发布表单(单击提交按钮并填写必填字段).

例:

    // Create a request using a URL that can receive a post. 
    WebRequest request = WebRequest.Create ("http://www.contoso.com/PostAccepter.aspx ");
    // Set the Method property of the request to POST.
    request.Method = "POST";
    // Create POST data and convert it to a byte array.
    string postData = "This is a test that posts this string to a Web server.";
    byte[] byteArray = Encoding.UTF8.GetBytes (postData);
