.NET – uses a CLR type on a Visual Basic key (such as `string`) (for example,` system.string` or `[string]`) Do you have any imagination?

We all know that in C#, there is no difference whether you use String (CLR class) or string (C# keyword). For more information, please refer to the following question

> What is the difference between String and string in C#?

So far, my impression is that the same is true for VB.NET. The language specification even says (emphasis mine):

The primitive types are identified through keywords, which are aliases for predefined types in the System namespace. A primitive type is completely indistinguishable from the type it aliases : writing the reserved word Byte is exactly the same as writing System.Byte.

So, I was very surprised to see that Visual Studio 2015 is different: Visual Studio allows you Specify the frame name (Int32 / Int64 / DateTime / …) preferences (tools/options/text editor/basic/code style) native VB keywords (integer/long/day/…).

The problem is: once you tell Visual Studio that you prefer the Framework name, the automatically generated code uses [String] (using [] VB keyword escape, similar to C#’s @) instead of String (object, single and all the same) VB key Word matches other types with the Framework type name). I think this is wrong (and have submitted a Connect issue) because the brackets make the code messy, and as shown above, whether you use [String] (due to VB’s automatic system import Effectively refer to System.String), it will not produce semantic differences) or String (VB keyword alias System.String).

However, since the Visual Studio developers are very smart, I finished It’s all possible to ignore something, and it actually makes sense to use [String] instead of String, so my question is:

Is it possible to use [String] instead of String in Visual Basic? Any conceivable advantages, or the Visual Studio editor just “does something wrong” and uselessly messes up the automatically generated code?

I think using String (refers to (1)) will be more continuous than [String]. In the whole The local use of [String] just doesn’t look good in the color of VB syntax, because it looks like a common type instead of a keyword. I think that when coloring with VB syntax, in addition to its appearance, in the code There is no possible advantage of using [String] instead of String.

I think using String (refers to (1)) will be more continuous than [String]. Using [String] in the whole place is only in the syntax color of VB It doesn’t look good because it looks like a normal type instead of a keyword.
