💡 Problem: You have an ASP.NET Web API (version 4) REST service, and you need to pass an array of integers. However, you're encountering some roadblocks on the way. 😓

💥 Solution: To pass an array of integers to your ASP.NET Web API, you can follow these simple steps:

1. Define your action method:

public IEnumerable<Category> GetCategories(int[] categoryIds) {
    // code to retrieve categories from the database
}

1. Construct your URL:

To pass the array, you need to append the integers as a comma-separated list to the query parameter. For example:

/Categories?categoryids=1,2,3,4

🧐 Explanation: By default, ASP.NET Web API can automatically bind simple types from the URI, such as integers. However, when dealing with arrays of integers, you need to ensure that the query parameter is correctly formatted. In the example above, we appended the integers "1,2,3,4" to the categoryids query parameter.

🚀 Call-to-Action: Now that you know how to pass an array of integers to ASP.NET Web API, you can effortlessly handle this scenario in your own projects! Give it a try and see the results for yourself. 😄
