如何在asp.net中从Web表单截取URL？

Is there a way to do this without any exe files or 3rd party things? I cannot use windows form components in web application and I am in need of taking screenshots of different URLs programmatically. Any idea will be appreciated.

没有任何exe文件或第三方的东西有没有办法做到这一点？我无法在Web应用程序中使用Windows窗体组件，我需要以编程方式截取不同URL的屏幕截图。任何想法将不胜感激。

JavaScript can read the DOM and render a fairly accurate representation of that using canvas. I [@Niklas] have been working on a script which converts html into an canvas image.

JavaScript可以读取DOM并使用画布呈现相当准确的表示形式。我[@Niklas]一直致力于将html转换为画布图像的脚本。

Note: You will need to write a web service/web method that accepts a base64 encoded string as an input parameter, and then saves that string (in its raw form, or converted to a file.)

注意：您需要编写一个Web服务/ Web方法，该方法接受base64编码的字符串作为输入参数，然后保存该字符串（以其原始格式或转换为文件）。

Example usage of html2canvas:

html2canvas的示例用法：

var imageAsBase64;

$('body').html2canvas({
    onrendered: function(canvas) {
        imageAsBase64 = canvas.toDataURL();

        // You now have a base64 string, representing a "screenshot" of 
        // your <body> element, which you can POST to your web service.

  }
});
