You can’t allocate classes on the stack in C#, unlike C++.
The new keyword calculates the number of bytes needed for the specified object and allocates enough memory from the managed heap.
C# object variables are a reference to the object in memory, not the object itself.
Here are a few handy properties and methods that are found on the System.Environment class:
Current OS: System.Environment.OSVersion
Current working directory: System.Environment.CurrentDirectory
string[] of drives on the machine: System.Environment.GetLogicalDrives()
Version of .NET app is running under: System.Environment.Version
Current machine name: System.Environment.MachineName
Newline symbol for the current environment: System.Environment.NewLine
Number of processors on the current machine: System.Environment.ProcessorCount
Full path to system directory: System.Environment.SystemDirectory
User name application is running under: System.Environment.UserName
Below are a few different variations that can be done on the Main method.
Return type is void, string array as argument:
Return type is void, no arguments:
Return type is int, no arguments:
Return type is int, string array as argument:
Besides accessing them via the ‘string[] args’ parameter, you can access command-line arguments using
When you do this, you are not required to define the Main() method as taking a string array.
I’ve come across a few debuggers that should help when on a box that doesn’t have Visual Studio on it:
I’ll have to do some more research and see if they are promising.
csc.exe /target:winexe – prevents a console window from appearing in the background
cordbg.exe assembly – loads .pdb file
b: set or display breakpoints
del: remove one or more breakpoints
g: continue debugging
p: print all loaded variables
o: step out of the current function
si: step into the next line
so: step over the next line
ex: exit the debugger
