Add SetContentFromEnumCollection method to RequestInformation class

[Copilot]

• Explore repository structure and understand the issue
• Review existing code in RequestInformation.cs
• Build and test the project to verify current state
• Add SetContentFromEnumCollection method to RequestInformation class
• Add tests for the new method
• Build and test to verify changes (all 171 tests pass)
• Verify method exists in compiled assembly
• Refactor to use foreach loop instead of enumerator pattern per code review feedback

Summary

Added the missing SetContentFromEnumCollection method to the RequestInformation class and refactored to use a foreach loop for finding the first non-null item. This resolves the compile error that occurred when Kiota generates C# clients for OpenAPI specs with enum array request bodies.

All tests pass successfully.

Original prompt

This section details on the original issue you should resolve

<issue_title>Array of enums in a request generates code (C#) that produces a compile error</issue_title>
<issue_description>### What are you generating using Kiota, clients or plugins?

API Client/SDK

In what context or format are you using Kiota?

Nuget tool

Client library/SDK language

Csharp

Describe the bug

With an OpenAPI description that has a route with request body of enum array. Kiota will generate a C# client that has a compile error:

Error CS1061 : 'RequestInformation' does not contain a definition for 'SetContentFromEnumCollection' and no accessible extension method 'SetContentFromEnumCollection' accepting a first argument of type 'RequestInformation' could be found (are you missing a using directive or an assembly reference?)

RequestInformation type has a method SetContentFromEnum but not the needed SetContentFromEnumCollection

Expected behavior

Kiota should generate code that compiles.

How to reproduce

Problem can be reproduced by generating a C# client with the provided Open API description. Command used to generate the client was:

dotnet kiota generate -l CSharp -c Client -n ConsoleApp1 --openapi example.yaml -o ./Client
