hexadecimal numbers in C#

Ranger49

In C++ you can assing a variable a value of for instance 0xAAAA; I tried this in C# but it didn't work. What is the syntax like in C# when assigning a hexadecimal number? I couldn't find an example of this in books about C# which I checked, but I am sure people here know the answer to my question. Thanks! Ranger.

It works in c# too. ShellAPI constants[^]

int x = 0xAAAA;

Thanks, I wondered... I think my error message was caused by the fact that I didn't know how many 'A's fit into a short type number. Ranger

Guess you know now ;P short = 2 bytes int = 4 bytes long = 8 bytes

Don't forget to pay attention to whether that short number is signed or unsigned!

short a = 0x7AAA; // OK!
short b = 0xAAAA; // Doh! Won't work!
ushort c = 0xAAAA; // OK!

You can also use the 'unchecked' syntax to force it to be a signed short.

short x = unchecked((short)0xAAAA); // Also OK!
