C# get element by name | 易学教程

Soo ive figured out how to get element by id, but i dont know how i can get element by name Here is my code:

private void SendData()
{
    webBrowser1.Document.GetElementById("textfield1").SetAttribute("value", textBox1.Text);
    webBrowser1.Document.GetElementById("textfield2").SetAttribute("value", textBox1.Text);
}

The problem is in my html code only textfield1 is a id but textfield2 is name soo i want to figure out how to get textfield2

Here is my html code:

<html>
    <input type="text" id="textfield1" value="TEXT1"><br>
    <input type="text" name="textfield2" value="TEXT2"><br>
    <input type="submit" value="Submit">
</html>

You can get an HtmlElementCollection - for example, using GetElementsByTagName method. Then, HtmlElementCollection has GetElementsByName method:

webBrowser1.Document
    .GetElementsByTagName("input")
    .GetElementsByName("textfield2")[0]
        .SetAttribute("value", textBox1.Text);

You can use HtmlElementCollection.GetElementsByName to take the value of the elements

webBrowser1.Document.GetElementsByName("textfield2").SetAttribute("value", textBox1.Text);

EDIT

foreach (HtmlElement he in webBrowser1.Document.All.GetElementsByName("textfield2"))
{
    he.SetAttribute("value", textBox1.Text);
}

You can't access the elements directly by name, but you could access it by finding the input tags first, and indexing into the result to find the tags by name.

webBrowser1.Document.GetElementsByTagName("input")["textfield2"]

webBrowser1.Document
    .GetElementsByTagName("input")
    .GetElementsByName("textfield2")[0]
