嗨,我必须将某些节点从 1 XML 替换为更大的web.config.

<?xml version="1.0" encoding="Windows-1252" standalone="yes"?>
  <VFPData>
    <site>
      <sitename></sitename>
      <appname></appname>
      <cookie>.cookiename</cookie>
      <host></host>
      <port>1234</port>
      <database></database>
      <userid></userid>
      <password></password>
    </site>
  </VFPData>

所以我必须复制过来<port>web.config

如果要将两个文件都视为文本文件,可以使用 StreamWriter 和 StreamReader。

using System;
using System.IO;

class Test 
{
    public static void Main() 
    {
        string path = @"c:\temp\MyTest.txt";
        // This text is added only once to the file. 
        if (!File.Exists(path)) 
        {
            // Create a file to write to. 
            using (StreamWriter sw = File.CreateText(path)) 
            {
                sw.WriteLine("Hello");
                sw.WriteLine("And");
                sw.WriteLine("Welcome");
            }   
        }

        // This text is always added, making the file longer over time 
        // if it is not deleted. 
        using (StreamWriter sw = File.AppendText(path)) 
        {
            sw.WriteLine("This");
            sw.WriteLine("is Extra");
            sw.WriteLine("Text");
        }   

        // Open the file to read from. 
        using (StreamReader sr = File.OpenText(path)) 
        {
            string s = "";
            while ((s = sr.ReadLine()) != null) 
            {
                Console.WriteLine(s);
            }
        }
    }
}

是的,这涵盖了流,并且非常适合文本。但是,您正在编辑 XML,因此可以更进一步。由于两者都在 XML 中,您可以使用XDocument对象(这将允许 Linq)。这将允许您读取原始流,将要复制的节点存储为变量,然后打开 web.config 文件并添加节点。
