```csharp
namespace Aspire.Hosting;

public sealed class InteractionInputCollection
    : System.Collections.Generic.IEnumerable<Aspire.Hosting.InteractionInput>,

      System.Collections.Generic.IReadOnlyList<Aspire.Hosting.InteractionInput>,
      System.Collections.IEnumerable
{
    // ...
}
```

## Constructors

- [InteractionInputCollection(IReadOnlyList<InteractionInput>)](/reference/api/csharp/aspire.hosting/interactioninputcollection/constructors.md#constructor-ireadonlylist-interactioninput) -- Initializes a new instance of the [InteractionInputCollection](/reference/api/csharp/aspire.hosting/interactioninputcollection.md) class.

## Properties

- [Count](/reference/api/csharp/aspire.hosting/interactioninputcollection/properties.md#count) : `int` `get` -- Gets the number of inputs in the collection.
- [Names](/reference/api/csharp/aspire.hosting/interactioninputcollection/properties.md#names) : `IEnumerable<string>` `get` -- Gets the names of all inputs in the collection.

## Methods

- [ContainsName(string)](/reference/api/csharp/aspire.hosting/interactioninputcollection/methods.md#containsname-string) : `bool` -- Determines whether the collection contains an input with the specified name.
- [GetEnumerator](/reference/api/csharp/aspire.hosting/interactioninputcollection/methods.md#getenumerator) : [IEnumerator<InteractionInput>](/reference/api/csharp/aspire.hosting/interactioninput.md) -- Returns an enumerator that iterates through the collection.
- [TryGetByName(string, InteractionInput?)](/reference/api/csharp/aspire.hosting/interactioninputcollection/methods.md#trygetbyname-string-interactioninput) : `bool` -- Tries to get an input by its name.

## Indexers

- [this[string]](/reference/api/csharp/aspire.hosting/interactioninputcollection/indexers.md#this-string) : [InteractionInput](/reference/api/csharp/aspire.hosting/interactioninput.md) `get` -- Gets an input by its name.
- [this[int]](/reference/api/csharp/aspire.hosting/interactioninputcollection/indexers.md#this-int) : [InteractionInput](/reference/api/csharp/aspire.hosting/interactioninput.md) `get` -- Gets an input by its index.
