我试过这段代码：

    using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string xmlString = System.IO.File.ReadAllText(@"d:\adilipman1937067724.xml");

            XmlDocument doc = new XmlDocument();
            doc.Load(xmlString);
            string t = doc.InnerText;

            textBox1.Text = t;
        }
    }
}

但出现错误：

错误：无效的 URI：Uri 字符串太长。我试图读取的文件是我和我兄弟的信使中的聊天记录的 xml。文件大小为：492kb。

获取错误异常消息：

几件事。

查看 xml 文档格式是否正确的最简单方法是在 Internet Explorer 中打开它。它会告诉你是否有问题。

一种查看 xml 文档内容的简单方法，去除了所有 xml 标记：

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\tt.xml");
string xmlString = doc.InnerText;

上面的方法也会告诉你你的xml文档是否有问题。

您的调用语法看起来是正确的，所以我认为您的 xml 文档一定有问题。先解决这个问题（一次一个问题！），然后再解决。

首先，您得到的编译错误是正确的，您需要关闭您的字符串文字。

string xmlString = System.IO.File.ReadAllText(@"C:\tt.xml");

您使用的方法从文件中读取所有文本，因此您当然会看到标签！

如果您只需要节点值，则将 xml 加载到 XmlDocument 中并使用 InnerText 属性。

        var doc = new XmlDocument();
        doc.Load(@"C:\tt.xml");
        var str = doc.InnerText;

变量 str 将包含文本，减去 xml 标记。
