Lazy<T> in C# 4.0

Before C# 4.0 there was no on demand initialization by default. So at the time of declaration we need to create a value or object will be null or we have to create on demand initialization via coding.. But with C# 4.0 we now have lazy class. As per MSDN it support lazy initialization so it means if we use lazy class then it will initialize the object at the time of demand.

It is very useful for UI responsiveness and other scenario's.  Lazy initialization delays certain initialization and  it’s improve the start-up time of a application. In the earlier framework if we need this kind of functionality we have to do it manually via coding but from C# 4.0 onwards it have Lazy<T> class. With the Help of this we can improve the responsiveness of C# application. Following is a simple example.

Lock keyword in C#

As we have written earlier we have now multi-core CPU for our computers and laptops and to utilize that we need to use threading in code. Now if we create thread and access same resource at same time then it will create a problem at that time locking become quite essential in any programming language.

Let’s consider a scenario. We are having a small firm of computers and each computer is shared by two employees and they need to use computer for putting their sales data in excel sheet. So they can not work together at same time and one has to work and other has to wait till first one complete the work. Same situation can be occurred in programming in where we are using same resource for multiple thread.

C# provides locking mechanism via lock keyword. It restricts code from being executed by more then one thread at a time. That is the most reliable way of doing multi threading programming.

Where I can find SQL generated by Linq-To-SQL

Yesterday I have written a blog post about Where I can find SQL Generated by Entity Framework? and same day I got request from one of the our reader Ramesh that how I can find SQL generated by Linq-To-SQL?. I thought its a good idea to write a blog post to share amongst all who need this instead of reply in comments.  In this post I am going to explain how we can get SQL generated by Linq-To-SQL.

For this post I am going to use same table like following. A customer table with two columns CustomerId and CustomerName.

Where I can find SQL Generated by Entity framework?

Few days back I was optimizing the performance with Entity framework and Linq queries and I was using LinqPad and looking SQL generated by the Linq or entity framework queries. After some point of time I got the same question in mind that how I can find the SQL Statement generated by Entity framework?

After some struggling I have managed to found the way of finding SQL Statement so I thought it would be a great idea to write a post about  same and share my knowledge about that. So in this post I will explain how to find SQL statements generated Entity framework queries.

To demonstrate the idea Let’s a very simple console application with C# and then  create a table called ‘Customer’ with CustomerId and CustomerName field in sql server.

Caller Info Attributes in C# 5.0

In c# 5.0 Microsoft has introduced a Caller information attribute. It’s a new feature that is introduced in C# 5.0 and very useful if you want to log your code activities. With the help of this you can implement the log functionality very easily. It can help any programmer in tracing, debugging and diagnostic of any application.
With the help of Caller Information we can get following information over there.

1. CallerFilePathAttribute: With help of  this attribute we can get full path of source file that contains caller. This will be file path from which contains caller at compile time.
2. CallerLineNumberAttribute:  With the help of this attribute we can get line number of source file which the method is called.
3. CallerMemberNameAttribute: With the help of this attribute we can get the method or property name of the caller.

Let’s write a simple example for that to see how its works. Following is a code for that.
