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);


回答2:

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"]

or

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