在asp.net中的div截圖

Question

我想在asp.net中截取Div元素的截圖並將其保存到磁盤。我不想使用html2canvas庫或html5 canvas元素。方法可以是服務器端或客戶端。

未經檢驗的，但發現這一點：

public Bitmap GenerateScreenshot(string url, int width, int height) 
{ 
    // Load the webpage into a WebBrowser control 
    WebBrowser wb = new WebBrowser(); 
    wb.ScrollBarsEnabled = false; 
    wb.ScriptErrorsSuppressed = true; 
    wb.Navigate(url); 
    while (wb.ReadyState != WebBrowserReadyState.Complete) 
    { 
     Application.DoEvents(); 
    } 

    // Set the size of the WebBrowser control 
    wb.Width = width; 
    wb.Height = height; 

    if (width == -1) 
    { 
     // Take Screenshot of the web pages full width 
     wb.Width = wb.Document.Body.ScrollRectangle.Width; 
    } 

    if (height == -1) 
    { 
     // Take Screenshot of the web pages full height 
     wb.Height = wb.Document.Body.ScrollRectangle.Height; 
    } 

    // Get a Bitmap representation of the webpage as it's rendered in the WebBrowser control 
    Bitmap bitmap = new Bitmap(wb.Width, wb.Height); 
    wb.DrawToBitmap(bitmap, new Rectangle(0, 0, wb.Width, wb.Height)); 
    wb.Dispose(); 

    return bitmap; 
}
