[RESOLVED] Ref int unsafe code in C#

[DaveDavis]

I come across some C# codes as C++'s pointer. But I never used such technique. Please explain how it works.

ref int val2 = ref this.intCounts;
ref reference = ref val2;
val2 = reference + 1;

it seems to be this.intCounts++. Does .NET 2.0 supports above codes?

Please explain how it works.

The explanation is in the documentation, which is the first place you should always look. VS has a Help menu for a reason.

Does .NET 2.0 supports above codes?

It's got nothing to do with the .NET Framework version because it's not a .NET feature. What matters is the C# version because this is a C# language feature. I don't know what version of C# this feature was introduced in but as long as you are using that version of C# or later, you can target any .NET version supported by that IDE.

By the way, this is not unsafe code because it's not using pointers. Pointers are actually variables that contain numeric memory addresses. That this code is using .NET references.

Thanks jmci.
