| Operator (C# Reference)
Binary | operators are predefined for the integral types and bool. For integral types, | computes the bitwise OR of its operands. For bool operands, | computes the logical OR of its operands; that is, the result is false if and only if both its operands are false.
Remarks
User-defined types can overload the | operator (see operator).
Example
// cs_operator_OR.cs
using System;
class MainClass
{
static void Main()
{
Console.WriteLine(true | false); // logical or
Console.WriteLine(false | false); // logical or
Console.WriteLine("0x{0:x}", 0xf8 | 0x3f); // bitwise or
}
}
Output
True False 0xff
