ITBLogs.InfoUse tryparse if that is possible or have a validation
I faced a number of error for parsing a string into int. In most of cases, there is a validation missing.
Code
If (IsNumeric(str)) | |
{ | |
int i =0; | |
Int32.TryParse(str,out i); | |
} |
You can use regex inside IsNumber or use foreach loop to check whether each character is numberic.
BUT NEVER NEVER DO LIKE THIS:
Code
try | |
{ | |
int i= Int32.Parse(i); | |
} | |
catch(FormatException) | |
{ | |
// Error Hanlding | |
} |
Try-catch is an expensive operation!!!!!!!!
Secondly, I like to use TryParse even in the case, the progam can tolrate invalid value. TryParse can allow the logic to continue execution. I hate some things like stack track on the screen.
Server Side logic vs Client Side logic
I think Server Side and Client Side, both have advantages and disadvantages.
Server Side:
Adv:
- More efficiency
- Easy to scale up(if the process is too complex, we can use load balancing)
Dis:
- Hard to deploy, to some complex operations, it may be required CLI store procs.
- More expertises required
Client Side:
Adv:
- Easy to be implement, You need to know C#
- Easy to deploy
- Easy to be manage
Dis:
- Less efficiency
I think, in generally, for complex operations, we can try to put that into the server side. For simple operations, just putting them into the client side logic. That is simple.

Email search are very very important
Nowadays, the most of webmail providers, such as Yahoo, Google and MS, provided a huge storage or even unlimited. Therefore, you will have a lot of email. Now, I got 11915 in my inbox at Yahoo and I have around a hundred new incoming email per day. This morning, I need to find an email which have some information I need but I got that email at the early of this year, maybe Jan or Feb(I can't remember). Well, email search is my life saver. I remember some keywords in email and I know the email received this year. I entered the keyword and limited this year. I can't find the exact emai. But I found an email with similar information. They are a kind of related. It should be received similar period of time. Then I got my inbox, went to the page has the email I found and I scrolled a page. Then I found the email I need. So, email with a search function, that is a "must have" function!
