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。
