In day to day development, we all are very familiar with Exception handling. We pretty much all know that we should wrap the code which may cause for any error in try/catch block and do something about error like give a error message to end user. Here I am not going to explain about Exception handling in C#. Instead I am going to talk about a particular aspect of Exception handling, which is "throw" vs "throw ex".
You can also find my other articles related to C#, ASP.Net, jQuery, Java Script and SQL Server. I am writing this post because I was asked this question recently in a interview and unfortunately I didn't know the answer. So I am posting this for those guys who uses "throw" and "throw ex" frequently but don't know the differences (not all,some knows).

Difference between “throw” and “throw ex”
Take a look on the below code snippest-| throw ex | throw |
|---|---|
try
{
//Code which fails and raise the error
}
catch (Exception ex)
{
throw ex;
}
| try
{
//Code which fails and raise the error
}
catch (Exception ex)
{
throw;
}
