The keyword "into" in a query comprehension means two different things, depending on whether it follows a join or select/group. If it follows a join, it turns a join into a group join. If it follows a select or group then it introduces a query continuation...

I got an email the other day that began: I have a question about fixed sized buffers in C#: unsafe struct FixedBuffer { public fixed int buffer[100]; } Now by declaring buffer as fixed it is not movable... And my heart sank. This is one...

This annotation to a comment in part five I think deserves to be promoted to a post of its own. Why do we disallow anonymous iterators? I would love to have anonymous iterator blocks. I want to say something like: IEnumerable<int> twoints...

Well that was a lovely vacation. It got off to a poor start but then it improved dramatically. Suppose you've got an "entrance" that is producing some largish number of "customers" on some schedule. You've got a bunch of "servers" who are handling...

Most people understand that there’s a difference between a “rectangular” and a “ragged” two-dimensional array. int[,] rectangle = { {10, 20}, {30, 40}, {50, 60} }; int[][] ragged = { new[] {10}, new[] {20, 30}, new[] {40, 50, 60} }; Here we have...

The C# switch statement is a bit weird. Today, four quick takes on things you probably didn't know about the switch statement. Case 1: You probably know that it is illegal to "fall through" from one switch section to another: switch(attitude...

Once more I'm revisting the myth that order of evaluation has any relationship to operator precedence in C# . Here's a version of this myth that I hear every now and then. Suppose you've got a field arr that is an array of ints, and some local variables...

I hear a lot of myths about C#. Usually the myths have some germ of truth to them, like " value types are always allocated on the stack ". If you replace "always" with "sometimes", then the incorrect mythical statement becomes correct. One I hear quite...

"Scope" has got to be one of the most confusing words in all of programming language design. People seem to use it casually to mean whatever is convenient at the time; I most often see it confused with lifetime and declaration space . As in "the memory...
