How do you put an "IF DEBUG" condition in a c# program?

How do you put an "IF DEBUG" condition in a c# program?

How do you put an "IF DEBUG" condition in a c# program so that, at run time, it will ignore a set of code if you are running in Debug mode and yet, execute a block of code if the program is not running in debug mode? I mean, what does it look like? Can you give me an example of what this source code would look like?

A situation where this can be used is if a time stamp is taken at the start of a block and another time stamp is taken at the end. THey will hardly differ at run time. Yet, if you are stepping through the code in debug mode, they will differ a lot, and error conditions in an "if block" might be kicked off leading to the untimely (pun) execution of some code.

There must be other cases where the need for such a thing exists.

I have used this in C++ but I forgot what it was. I tried googling but I did not get any results at first glance.

Also, what would be an "IF NOT DEBUG" condition and the closing "END IF"?

Code:

#if DEBUG
string conStr = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\..\myDebugDatabase.mdb";
#else
string conStr = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\..\myPublishDatabase.mdb";
#endif

OleDbConnection myCon = new OleDbConnection(conStr);

//Some code here

Hope this helps

it checks whether the DEBUG symbol exists in your code or not.
You can define these symbols using #define dirctive.
For best help I an exact bit of copy from the book professional C# 4 and .Net 4 :

Code:

#define ENTERPRISE
#define W2K

// further on in the file
#if ENTERPRISE
   // do something
   #if W2K
      // some code that is only relevant to enterprise
   // edition running on W2K
   #endif
#elif PROFESSIONAL
   // do something else
#else
   // code for the leaner version
#endif

Great wishes, Best Luck...
