base64

Hello, I need for someone to be able to put some text into a page and then this gets sent to the server, saved in the database, and else where this text is put into a javascript variable.

Basically like this:

Write("var myVar=\""+MyData+"\";");

What is the best way of escaping this data? Is there anything out there already to deal with things like ' and " and new lines? Is base64 my only option?

My serverside framework/language is ASP.Net/C#

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
