Do we reduce memory consumption when storing a String value that we use very frequent ? As far as I know, every time we do a "some string" declaration, a new string is constructed, instead of using the address of an existing one with the same value. Am I correct ? (I am not talking here about improving the code maintainability) ...

Is there built in .NET functionality for making state abbreviations out of state names? I know the function wouldn't be difficult to write, but I would assume that MS has thought of a more efficient way than the following x50: if statename.tolower = "new york" then statename = "NY" else if any other thoughts of making this more e...

I think i remember seeing something similar to the ?: ternary operator in C# that only had two parts to it and would return the variable value if it wasn't null and a default value if it was. Something like this: tb_MyTextBox.Text = o.Member ??SOME OPERATOR HERE?? "default"; Basically the equivalent of this: tb_MyTextBox.Text = o.Me...

This site explains about searching assemblies using .config file that has relative search path. I couldn't find the .NET configuration utility on Windows 7, so I just copied the config file to see it works. But I wonder why I can't find the .NET configuration tool in Windows 7. Where is the .NET configuration utility or equivalent i...

The ProcessMnemonic method is clearly the one to override. However, looking at how the Label control does it, for reference, shows that it r...

Here's what I've found: JSON.NET JSONSh...
