A co-worker of mine and I both do programming. He has made a class in C# and I am working on converting it to VB.NET. I got the full class converted except for a single line, and at this point I cannot figure it out so thought a fresh set of eyes maybe able to find my error.
Original C# code
using (var client = new HttpClient(new HttpClientHandler { AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate }))
Converted VB.NET code
Using client = New HttpClient(New HttpClientHandler With {Key .AutomaticDecompression = DecompressionMethods.GZip Or DecompressionMethods.Deflate})
Error
Name of field or Property being initialized in an object initialize must start with '.'.
Error is located under the 'Key'
Last note: I used a dreaded code-converter for most of it, so I am unsure where 'key' came from.
There are two concepts which have similar syntax but different semantics:
Anonymous Types
C#: new { A = 1, B = 2 }
VB: New With { Key .A = 1, Key .B = 2 }
Here, VB also allows you to add mutable (non-key) properties, which C# does not support:
New With { Key .A = 1, Key .B = 2, .SomeMutableProperty = 3 }
Hence, the Key keyword is important here.
Object Initializers for Named Types
C#: new MyClass { A = 1, B = 2 }
VB: New MyClass With { .A = 1, .B = 2 }
Here, existing properties of MyClass are set, so the Key keyword is irrelevant, and, thus, not allowed.
Apparently, your C# -> VB converter thought that this was an anonymous type, although it was an object initializer. Remove the Key keyword and send a bug report to the converter's developer.
Not sure where the Key has come from.
Running this through Instant VB gives the following, so it would concur with my thought that the Key is not required:
Option Infer On
Using client = New HttpClient(New HttpClientHandler With {.AutomaticDecompression = DecompressionMethods.GZip Or DecompressionMethods.Deflate})
