我正在尝试制作一个将网页加载到表单中的小程序，自动在页面上提交表单 - 这是一个更大的项目的一部分，但我无法让这部分正常工作。
当输入并提交正确的案件编号和日期 (mm-yy) 时，此网页会提供法院案件结果。
我在表单中创建了一个简单的 webBrowser 并将其命名为webBrowser1.
这是我的 Form.cs 代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(HandleRequest);
firstStep();
// secondStep();
}
private void firstStep()
{
webBrowser1.Url = new System.Uri("http://www.court.gov.il/NGCS.Web.Site/HomePage.aspx", System.UriKind.Absolute);
}
private void HandleRequest(object sender, WebBrowserDocumentCompletedEventArgs e)
{
webBrowser1.DocumentCompleted -= new WebBrowserDocumentCompletedEventHandler(HandleRequest);
HtmlElement caseNumber = ((WebBrowser)sender).Document.All["Header1_CaseLocatorHeaderUC2_BamaCaseNumberTextBoxHT"];
HtmlElement caseDate = ((WebBrowser)sender).Document.All["Header1_CaseLocatorHeaderUC2_BamaMonthYearTextBoxHT"];
caseNumber.Focus();
System.Windows.Forms.SendKeys.Send("(1)");
System.Windows.Forms.SendKeys.Send("(2)");
System.Windows.Forms.SendKeys.Send("(2)");
System.Windows.Forms.SendKeys.Send("(3)");
System.Windows.Forms.SendKeys.Send("(8)");
System.Windows.Forms.SendKeys.Send("{TAB}");
System.Windows.Forms.SendKeys.Send("(0)");
System.Windows.Forms.SendKeys.Send("(3)");
System.Windows.Forms.SendKeys.Send("(1)");
System.Windows.Forms.SendKeys.Send("(0)");
HtmlElement inputTag = webBrowser1.Document.All["Header1_CaseLocatorHeaderUC2_SearchHeaderCaseButton"];
inputTag.InvokeMember("Click");
}
}
}
如您所见 - 我正在输入如图所示的值，然后单击提交此表单的按钮，但它不起作用！？这个网页非常棘手，它使用验证输入的脚本，然后设置要提交的正确值，顺便说一下，他只在 IE < 10....
有什么想法吗？
编辑：
它现在正在工作 - 我正在解雇invoke两次，但我不知道问题出在哪里。
现在的新问题是我添加了一个按钮单击来触发该过程btnGet_Click，并且在触发此功能时出现错误-似乎DetailsTag已设置为空...但是当我在public Form1()其正常工作和加载中取消注释该功能时网站应有的样子。
firstStep()在按钮单击/公共表单中调用函数有什么区别？
为什么我会收到此错误？
