本文主要向大家介绍了C#编程控制IE打开网页,输入用户名、密码并登录的操作代码实例,通过具体的内容向大家展示,希望对大家学习C#编程有所帮助。
注意,要添加两个COM引用
Microsoft HTML Object Library
Microsoft Internet Controls
BUTTON1打开百度查询
BUTTON2模拟输入用户密码,并登录。
private void button1_Click(object sender, EventArgs e)
{
SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer();
ie.DocumentComplete += ie_DocomentComplete;
ie.Navigate("https://www.baidu.com");
ie.Visible = true;
compWait();
mshtml.HTMLDocument doc = ie.Document;
doc.getElementById("kw").innerText = "中国";
doc.getElementById("su").click();
}
private bool ie_read = false;
private void ie_DocomentComplete(object pDisp, ref object URL) //加载完成事件
{
ie_read = true;
}
private void compWait() //等待,直到加载完成
{
while (ie_read != true)
{
Application.DoEvents();
}
}
private void button2_Click(object sender, EventArgs e)
{
SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer();
ie.DocumentComplete += ie_DocomentComplete;
ie.Navigate("https://10.100.200.300/XXXXX/XXXXX.do");
ie.Visible = true;
compWait();
mshtml.HTMLDocument doc = ie.Document;
mshtml.IHTMLElementCollection userids = doc.getElementsByName("userid");
foreach (mshtml.IHTMLElement userid in userids)
{
userid.innerText = "xiaoming";
}
mshtml.IHTMLElementCollection passwords = doc.getElementsByName("password");
foreach (mshtml.IHTMLElement password in passwords)
{
password.innerText = "888888";
}
mshtml.IHTMLElementCollection syaincds = doc.getElementsByName("syaincd");
foreach (mshtml.IHTMLElement syaincd in syaincds)
{
syaincd.innerText = "0";
}
mshtml.IHTMLElementCollection logins = doc.getElementsByName("login");
foreach (mshtml.IHTMLElement login in logins)
{
login.click();
}
System.Threading.Thread.Sleep(3000);
mshtml.IHTMLElementCollection tencds = doc.getElementsByName("login");
foreach (mshtml.IHTMLElement tencd in tencds)
{
tencd.click();
}
}
