Question

我的智慧结束了。每当我尝试使用XPath选择节点时，我一直在使用HtmlAgilityPack获得此异常。即使我只用这个例子开始一个全新的解决方案，问题仍然存在（因此我的应用程序代码不会以某种方式干扰问题。网页没有任何问题，或者我的网络连接或类似的东西。我知道我有过以前这个工作。我甚至怀疑一个损坏的dll并重新下载它，但无济于事。任何想法？

using System;
using HtmlAgilityPack;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var web = new HtmlWeb();
            var doc = web.Load("http://www.google.com");
            var root = doc.DocumentNode;

            var links = root.SelectNodes("//a");
            // Error!  ArgumentOutOfRangeException: Index was out of range. 
            // Must be non-negative and less than the size of the collection.
        }
    }
}

/*

    Parameter name: index

       at ConsoleApplication1.Program.Main(String[] args)

编辑：

嗯......我不确定它是怎么发生的或它做了什么，但我发现.dll安装在GAC_MSIL文件夹中。删除它立即解决了问题。所以，没关系！

运行HtmlAgilityPack的ArgumentOutOfRangeException
