Getting environment variable in console app

Question

I need analyze my environment variable value(COPYCMD) Batch:

SET COPYCMD = /-y
SUPERCOPY.exe someFile.some someDirectory

SUPERCOPY - is my utility

SUPERCOPY code:

...
string environmentVar = Environment.GetEnvironmentVariable("COPYCMD");
...

This string always returns null. Also I have tried another way:

IDictionary environment = Environment.GetEnvironmentVariables();
if ((environment["COPYCMD"] as string).ToUpper() == "/-Y")
{
    DoSomething();
}

This way also doesn't work

Are you sure you have the element "COPYCMD" in your environmental variables? — Asaf Savich, Nov 20 '16 at 14:57

In batch files the space to the left of the equals symbol becomes part of the variable name. Remove the space. — Squashman, Nov 20 '16 at 15:01
Yes, when i use this cycle:foreach (DictionaryEntry de in Environment.GetEnvironmentVariables()) Console.WriteLine(" {0} = {1}", de.Key, de.Value); i see my COPYCMD — Sharky, Nov 20 '16 at 15:03

I believe the problem is that your environment variable has a trailing space in its name...

Try:

SET COPYCMD=/-y
