你应该能够解决Elelment.Id和Eleliment.Classname。

你看到它在循环中完成了。

由于元素集合正在重新调整，您可以使用Linq查询元素并重新调整对象。

  dim elm =（来自 webBrowser1 。 文件 。 全部

          其中a.Id =" username"和a.Classname =" input4" select a） SingleOrDefault（）

如果不是IsNoth ing（elm）然后

  dim id = elm.ID

  dim classname = elm.classname

end if if

尝试使用Linq语句或进入循环以查找所需的元素。

on the website there is same id textbox but when i am writing 
        WebBrowser1.Document.All("username").SetAttribute("value", username)
its writen different textbox with same id "username"

<input name="username" id="username" type="text" class="user" autocomplete="off"
placeholder="Kullanici Adi">

i need to reach second field but i couldnt reach 
<input type="text" id="username" class="input4"
 autocomplete="off" name="username" value="" required="" 
data-required="" data-pattern="^[a-zA-Z][a-zA-Z0-9]+$" 
data-minlenght="6" data-maxlenght="12"
 onkeyup="clearNonAlphaNum(this)">

You should be able to address the Elelment.Id and Eleliment.Classname.

You see it being done in the loop.

Since a collection of elements are being retuned, you can use Linq to query the elements and get an object retuned.

 dim elm = (From a in webBrowser1.Document.All

                   Where a.Id = "username" and a.Classname = "input4" select a)SingleOrDefault()

If not IsNothing(elm) then

  dim id = elm.ID

  dim classname = elm.classname

end if

Either try the Linq statement or go into a loop to find the element wanted.
