Gets a collection of all image tags in the document.
public:
property System::Windows::Forms::HtmlElementCollection ^ Images { System::Windows::Forms::HtmlElementCollection ^ get(); };
public System.Windows.Forms.HtmlElementCollection Images { get; }
member this.Images : System.Windows.Forms.HtmlElementCollection
Public ReadOnly Property Images As HtmlElementCollection
Property Value
A collection of HtmlElement objects, one for each IMG tag in the document. Elements are returned from the collection in source order.
Examples
The following code example examines the ALT
attribute of all of the images in the document, and sets a default ALT
attribute if a value is not already set.
private string[] GetImageUrls()
{
if (webBrowser1.Document != null)
{
HtmlDocument doc = webBrowser1.Document;
string[] urls = (string[])Array.CreateInstance(Type.GetType("System.String"), doc.Images.Count);
foreach (HtmlElement imgElement in doc.Images)
{
urls[urls.Length] = imgElement.GetAttribute("src");
}
return (urls);
}
else
{
return (new string[0]);
}
}
Private Function GetImageUrls() As String()
If (WebBrowser1.Document IsNot Nothing) Then
Dim Urls(WebBrowser1.Document.Images.Count) As String
For Each ImgElement As HtmlElement In WebBrowser1.Document.Images
Urls(Urls.Length) = ImgElement.GetAttribute("SRC")
Next
GetImageUrls = Urls
Else
Dim Urls(0) As String
GetImageUrls = Urls
End If
End Function
Remarks
Images returns a collection of HtmlElement objects. To access attributes, such as ALT
and SRC
, that are not directly exposed by HtmlElement, use the GetAttribute method.
To add a new image to a document, either create a new IMG
tag as a string, and assign it to the InnerHtml property of an element previously added to the HTML DOM; or use the CreateElement method, set its properties using SetAttribute, and add it as a child of an existing element using AppendChild.
