我正在查看
github上的PDF.js项目并查看他们的基本演示我已经想出了这个(整个视图)：
@{
ViewBag.Title = "GetPDFLetter";
Layout = null;
}
<!doctype html>
<html>
<head>
<title>PDF.JS TEST</title>

});

文件helloworld.pdf与视图位于同一文件夹中,但是当我运行项目时,没有任何内容被渲染,只是一个小矩形.我错过了什么吗？有什么特别考虑？谢谢你的帮助.
解决方法
终于搞清楚了.多么棒的PDF.js库.
我已经取得了creating a sample MVC3 project using PDF.js的自由.它遵循github上90％的PDF.js演示,除了一个微小的,自我解释的(在代码中的注释中解释)改变了向观众分配PDF文件路径.
