i decompiled an exe using different decompilers but i am unable to find main method in the decompiled code. What can be the reason?

Thanks for the points.
The answers:
1. You actually decompiled a DLL not an exe
Ans. It is an EXE

2. The code is obfuscated
Ans/Query. How to identify obfuscated code?

3.The main method was not name "main". You did not look hard enough.
And. I have used a number of decompilers including reflector, dotpeek etc. The decompiled output contained only classes. These classes are named as
$ArrayType$$$iu00$$aqw.cs
quit.cs
struct1.cs
$UnnamedClass$0xf0p9y646$88$.cs
etc

And all these classes contains is internal structures


internal struct Atquit
{
}

and interfaces

Help me find main method and let me know the information u require to guide me further
