I opened a large C# file (~16Mb) and this exception was thrown.

The code was generated automatically from xml schema, hence it's large size all in one file.  However, the code is fine as it can be opened OK with other editors. 

SharpDevelop Version : 2.2.1.2648
.NET Version         : 2.0.50727.832
OS Version           : Microsoft Windows NT 5.1.2600 Service Pack 2
Current culture      : English (United Kingdom) (en-GB)
Current UI language  : en-US
Working Set Memory   : 938560kb
GC Heap Memory       : 870918kb

Exception thrown:
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

I think I can safely categoize this bug as "won't fix".

Well, the memory consumption when opening large files should be improved... currently SharpDevelop allocates about 25MB per second for such a file. The application runs out of memory (due to a fragmented large object heap) before the garbage collector even gets a chance to run.

Perhaps large files should be handled differently, so that they don't invoke the large memory consumption?

Or as you suggest, a more memory efficient method could be used.
