[英]When signing 2 GB XML file SignedXml.ComputeSignature throwing out of memory exception in 64 bit windows with 8 GB RAM
[英]XML serialization: 64Bit Windows7, oct processor cored, 32GB RAM and OutOfMemory exception
处理500 MB
数据并尝试序列化时,
GetStringForStringBuilder(String value, Int32 startIndex, Int32 length, Int32 capacity)
抛出System.OutOfMemoryException
XML Serializer:
StringWriter xmlStr = new StringWriter();
XmlTextWriter twa = new XmlTextWriter(xmlStr);
lock(myLock)
{
mySerializer.WriteObject(twa, myHandlerMap); // OutOfMemoryException
twa.Flush();
twa.Close();
set.StringBuffer = xmlStr.ToString();
xmlStr.Dispose()
}
阅读以下链接的最后一段后: http : //blogs.msdn.com/b/vsofficedeveloper/archive/2008/10/10/stringbuilder-outofmemoryexception.aspx
我怀疑如果没有MS修复它是否有可能解决这个问题?

PLS。 让我知道它怎么解决?
对于xml来说500MB是相当大的,听到它不开心并不会让我感到惊讶。 如果可能的话,我会看一些基于流的东西,即XmlWriter
/ XmlReader
。 没有更多细节,目前尚不清楚这是否可行。 或者,考虑另一种格式! 说真的...... xml不适合大尺寸。
不过,首先要尝试的是...... 不要使用字符串 (或StringBuilder); 但是,通过XmlReader
/ XmlWriter
上的FileStream
直接从/向磁盘读/写。
我更希望将其直接序列化为文件。 500 MB是一个非常庞大的数据,并且在使用“chatty”xml进行序列化时会获得更多。
