奇怪的StringBuilder

[king2003]

using System;
using System.Text;

public sealed class App
{
static void Main()
{
// Create a StringBuilder that expects to hold 50 characters.
// Initialize the StringBuilder with "ABC".
StringBuilder inlineCode = new StringBuilder();
StringBuilder sb = new StringBuilder("ABC", 50);
sb=inlineCode;
// Append three characters (D, E, and F) to the end of the StringBuilder.
sb.Append(new char[] { 'D', 'E', 'F' });

// Append a format string to the end of the StringBuilder.
sb.AppendFormat("GHI{0}{1}", 'J', 'k');

// Display the number of characters in the StringBuilder and its string.
Console.WriteLine("{0} chars: {1}", sb.Length, sb.ToString());

// Insert a string at the beginning of the StringBuilder.
sb.Insert(0, "Alphabet: ");

// Replace all lowercase k's with uppercase K's.
sb.Replace('k', 'K');

// Display the number of characters in the StringBuilder and its string.
Console.WriteLine("{0} chars: {1}", sb.Length, sb.ToString());
Console.WriteLine("{0} chars1111: {1}", inlineCode.Length, inlineCode.ToString());
}
}
inlineCode这个值怎么会跟着sb变化呀

sb=inlineCode;
这不就是同一个StringBuilder了吗？

[lijin84100]

StringBuilder sb = new StringBuilder("ABC", 50);
sb=inlineCode;

是这一句的;问题吗,你设置断点测试一下,就知道了.

sb=inlineCode; 赋值以后，这两个变量的地址一样了

可以这样理解？

[lude8880]

sb=inlineCode; 你把inlinecode的指针传到sb上了，
换成 sb=inlinecode.toString(0;就成了

sb=inlineCode; 赋值以后，这两个变量的地址一样了
地址一样是哪个一样？和inlineCode 一样?

sb=inlineCode之后sb和inlineCode指向了同一个StringBuilder对象，这样能明白了？

我明白了谢谢
