CSharpClientGenerator : How to get parameter type-names of a method?

[KuldeepSinh]

Given I have instances of OpenApiDocument and OpenApiOperation, how can I programmatically get type-names of all the request parameters the C# method is going to generate in the request method?

For example, following is a signature of a method generated by the NSwag C# Client Generator.

System.Threading.Tasks.Task CreateFile(FileParameter file = null, System.Threading.CancellationToken cancellationToken = default(System.Threading.CancellationToken));

I would like to get the type-names of the parameter generated by the NSwage Client Generator.

I tried using new CSharpClientGenerator(doc, setting).GetTypeName(schema, nullability, "anonymous") to get the names.
I always get FileResponse instead of FileParameter.

May be this is not the right way.

Any help is appreciated. Thank you.

I was able to retrieve Required information from using CSharpOperationModel as follows.

var settings = new CSharpClientGeneratorSettings();
var clientGenerator = new CSharpClientGenerator(_openApiDocument, settings);
var operationModel =  new CSharpOperationModel(operation.Operation, (CSharpGeneratorBaseSettings)settings, clientGenerator, CSharpGeneratorBase.CreateResolverWithExceptionSchema(new CSharpGeneratorSettings(), _openApiDocument));


foreach (var parameterModel in operationModel.Parameters)     
{
     //access parmeterModel to retrieve meta-information like Type, Kind, etc.
}
