为什么没有使用StringBuilder作为参数的StringBuilder.Append重载？ [英] Why isn't there an StringBuilder.Append overload with StringBuilder as argument?

问题描述

为什么StringBuilder没有StringBuilder.Append（）重载？
参数？

有没有我错过的原因？

解决方案

我认为不会因为它没用。现在你可以这样做：


....

stringBuilder2.Append（stringBuilder1.ToString（））;

.. ..


我找不到为什么需要这样的方法。

参数？

我找不到为什么需要这样的方法。

你的理由将使所有现有的19个StringBuilder重载

无用。

问题是stringBuilder1.ToString（）创建了一个新的字符串我

想要避免。

你如何构建另一个？您也许可以重复使用它，即。使用

单字符串构建器而不是单独创建其中两个然后

组合它们？

Why isn''t there an StringBuilder.Append() overload with a StringBuilder as
argument?
Is there a reason that I missed?

解决方案

I think there isn''t because it would be useless. Now you can do:

....
stringBuilder2.Append(stringBuilder1.ToString());
....

I find no reason why one need such method.

Your "reason" would make all of the existing 19 overloads of StringBuilder
"useless".
The problem is that stringBuilder1.ToString() creates a new string which I
want to avoid.

How do you build the other one ? You could perhaps reuse it ie. using a
single string builder rather than creating separately two of them and then
combining them ?
