此博客展示了一段C#代码，定义了一个名为bar的类，其中包含Main方法及三个测试方法Test1、Test2、Test3。每个测试方法都对XML文本进行读写操作，使用了XmlTextReader和XmlTextWriter，分别采用不同方式处理输入的XML字符串，并输出输入输出字符串的长度。

using System;
using System.IO;
using System.Text;
using System.Xml;

namespace foo {
public class bar {
public static void Main() {
Test1();
Test2();
Test3();

}

public static void Test1() {
string strInput = "<?xml version='1.0' encoding='utf-16'?><foo><bar /></foo>";
XmlTextReader r = new XmlTextReader(new StringReader(strInput));
StringBuilder sb = new StringBuilder();
XmlTextWriter w = new XmlTextWriter(new StringWriter(sb));
w.WriteNode(r, false);
w.Flush();
string strOutput = sb.ToString();
Console.WriteLine("Input = {0}, Output = {1}", strInput.Length, strOutput.Length);
}

public static void Test2() {
string strInput = "<?xml version='1.0' encoding='utf-16'?><foo><bar /></foo>";
XmlTextReader r = new XmlTextReader(new StringReader(strInput));
MemoryStream ms = new MemoryStream();
XmlTextWriter w = new XmlTextWriter(ms, Encoding.Unicode);
w.WriteNode(r, false);
w.Flush();
ms.Position = 0;
StreamReader sr = new StreamReader(ms);
string strOutput = sr.ReadToEnd();
Console.WriteLine("Input = {0}, Output = {1}", strInput.Length, strOutput.Length);
}

public static void Test3() {
string strInput = "<?xml version='1.0' encoding='utf-16'?><foo><bar /></foo>";
XmlTextReader r = new XmlTextReader(new StringReader(strInput));
MemoryStream ms = new MemoryStream();
XmlTextWriter w = new XmlTextWriter(ms, Encoding.UTF8);
w.WriteNode(r, false);
w.Flush();
ms.Position = 0;
StreamReader sr = new StreamReader(ms);
string strOutput = sr.ReadToEnd();
Console.WriteLine("Input = {0}, Output = {1}", strInput.Length, strOutput.Length);
}

}
}
