[C#][CSharp] Generating code for an array of enums produces incorrect output

[mkarpusiewicz]

Description

For models that contain array of items that are enums output enum code produced doesn't compile.

Swagger-codegen version

I've tried 2.2.1 and 2.2.2 - on both problem occurs.

Swagger declaration file content or url

Minimal example:

"TestModel": {
	"required": ["Login"],
	"type": "object",
	"properties": {
		"Login": {
			"maxLength": 255,
			"minLength": 0,
			"type": "string"
		},
		"Types": {
			"type": "array",
			"items": {
				"format": "int32",
				"enum": [0, 1, 2],
				"type": "integer"
			}
		}
	}
}

Full example json file:

Command line used for generation

java -jar swagger-codegen-cli.jar generate -i enum-test.json -l csharp -o enum-test -DpackageName="WebApiTest"

Steps to reproduce

1. With given enum.test.json use command line above to generate C# classes.
2. TestModel.cs contains enum TypesEnum with members like:

[EnumMember(Value = ""0"")]
_0 = "0",

Int values are treated like strings and code doesn't compile.

Correct code should be:

[EnumMember(Value = "0")]
_0 = 0,

@mkarpusiewicz thanks for reporting the issue with the spec and I could repeat it.

The issue has to do with array of enum as after removing the array the code compiles fine.

I'll take a look this weekend to see if I can find a fix for it.

@wing328 Thanks, give me a shout if I can help with anything.
