Question

正如问题所暗示的那样，我正在尝试将字符串用作HtmlAgilityPack DocumentNode路径。当我运行代码时，它说;路径中的非法字符。

我的代码：

类别：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using HtmlAgilityPack;
using System.IO;
using System.Dynamic;

namespace Class_xlAccountSCRead_ClassBuild
{
    public class xlAccount_SCProcess
    {
        public static string ascDir { get; set; }
        public static string ascFav { get; set; }
        public static string accountSourceCodeDir;

        public static void ascRead()
        {
            HtmlAgilityPack.HtmlDocument docc = new HtmlAgilityPack.HtmlDocument();
            HtmlDocument doc = new HtmlDocument();
            doc.Load(ascDir);
            ascFav = doc.DocumentNode.SelectNodes("//*[@id=\"favoritesContent\"]/div[2]/div[2]/ul")[0].InnerHtml;


        }

    }


}

形式：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;
using System.Dynamic;
using HtmlAgilityPack;

namespace xlAccountSCRead_ClassBuild
{
    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {

            Class_xlAccountSCRead_ClassBuild.xlAccount_SCProcess.ascDir = "@" + "\"" + textBox1.Text + "\"";

            //await Task.Delay(100);
            Class_xlAccountSCRead_ClassBuild.xlAccount_SCProcess.ascRead();

            textBox2.Text = Class_xlAccountSCRead_ClassBuild.xlAccount_SCProcess.ascFav;
        }

        private void button2_Click(object sender, EventArgs e)
        {
            Class_xlAccountSCRead_ClassBuild.xlAccount_SCProcess.ascDir = "@" + "\"" +  textBox1.Text + "\"";

            label1.Text = Class_xlAccountSCRead_ClassBuild.xlAccount_SCProcess.ascDir;
        }
    }
}

该过程由名称空间Class_xlAccountSCRead_ClassBuild中的ascRead运行。

看起来你正在尝试使用C＃string literal以这种方式构建字符串，如下所示：

string cs_literal = @"the_actual_path_goes_here";

请注意您的代码在这里......

string your_string = "@" + "\"" +  textBox1.Text + "\"";

...将生成相当于此C＃字符串文字的内容：

string cs_literal = "@\"the_actual_path_goes_here\"";

话虽如此，引用在路径上是非法的，因此路径中的非法字符＆＃34;例外。实际上，你不需要在这里进行所有转义，因为你输入的C＃代码不是字符串文字。只需传递TextBox 中的字符串：

string your_string = textBox1.Text;

如何将字符串用作HtmlAgilityPack文档路径？
