C# asp.net coding usefull tips

Use proper naming conventions - in a large project you will end up with more than thousand variable names , methods , etc.
So in order to facilitate the autocompletion feature fully name as follows:
- the names of the variables - if it is control , find out consisten 3 letter abbreviation for type of control and than the name - for example - if I have a column name in the database called FirstName - the name of the textbox , which will pass the value to the db is txtFirstName, if it is label is should be labFirstName , if I have panel containing controls the name of the panel is panSearch. Thus each time you remember - it is a text field you just type txt and will get list (hopefully smaller than 20 items in your page / class with all the txt fields ; )
- the names of the methods - well Microsoft advices use for example SearchClick - I say use ClickSearch - once you type Click you will get all the EventHandlers which you have designed to response to click on a button , or CheckUserIsActivie

- Use longer names of classes to remember them better - later one use find and replace LongNameOfClass. with lnc once you have used the class so often that you remember the short name for sure - the same stands for variables

- use short name for variables , which are obvious from the context - e.g. later on when having to debug or just simply review what the ... I have written ... it will be 100% sure what this variable stands for . For example:
public static void SanitizeForSQL ( ref string s , char c )
{
s = c + s + c ;
}
