不知道这是否解决了你的问题。但请看这一张

Answer 2

当你想要向StringBuilder添加文本，而当前的容量不足时，StringBuilder会尝试将其容量加倍。

因此字符串的最大容量是2^32，但在本例中，它需要从17MB增加到34MB。可能你正试图将文本附加到一个大的StringBuilder中？

您需要使用.NET内存探查器来检查应用程序中的内存泄漏位置。http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=navclient&gfns=1&q=.NET+memory+profilers

看起来你正在使用非常大的字符串进行操作，或者其他一些内存泄漏导致内存压力。
