What is the equivalent of |= in Visual Basic?

Question

What is the equivalent of the |= operator in Visual Basic? For example (C#):

flags |= MyEnum.SomeFlag

Answer 1

flags = flags Or MyEnum.SomeFlag

Answer 2

In C#, |= is the Or assignment operator .

There's no equivalent operator in VB.

See the list of Assignment Operators (Visual Basic) .

Answer 3

Visual Basic does not support compound assignment operators as shown in the C# sample. You'll need to use the expanded form of the assignment and the vb version of the bitwise or operator (simple Or )

flags = flags Or MyEnum.SomeFlag

Answer 4

flags = flags Or MyEnum.SomeFlag

Not that this is any sort of official source, but check out these pages:

It seems to me that there isn't an existing combination of the bitwise-or-plus-assignment operator in VB.NET. But there is a bitwise-or operator, and an assignment operator, which you can combine manually:

flags = flags Or MyEnum.SomeFlag
