Hi all,

I want to create a global MemoryMappedFile in C# 4.0 using following call:

string MemoryMappedFileName = "Global\\20E9C857-C944-4C35-B937-A5941034D073";
ioBuffer = MemoryMappedFile.CreateNew(MemoryMappedFileName, totalIoBufferSize);

This always throws following exception "System.UnauthorizedAccessException: Access to the path is denied." If I remove the "Global\" identifier from the memorymapped filename it works but I need a memory mapped file existing accross terminal sessions.

thanks, Christoph

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
