Octal equivalent in C#

In C language octal number can be written by placing 0 before number e.g.

 int i = 012; // Equals 10 in decimal.

I found the equivalent of hexadecimal in C# by placing 0x before number e.g.

 int i = 0xA; // Equals 10 in decimal.

Now my question is: Is there any equivalent of octal number in C# to represent any value as octal?
