A collection of T that is optimized for minimal space in the case of a single element.
generic <typename T>
where T : classpublic value class OneOrMany[System.Diagnostics.DebuggerDisplay("Count = {Count}")]
public struct OneOrMany<T> where T : class[<System.Diagnostics.DebuggerDisplay("Count = {Count}")>]
type OneOrMany<'T (requires 'T : null)> = structPublic Structure OneOrMany(Of T)Type Parameters
- T
Elemental type which must be a reference type. Note: null may not be used as a value in the collection.
- Inheritance

OneOrMany<T>
- Attributes
Remarks
While this type has a GetEnumerator() method, it does not implement IEnumerable<T>. This is to eliminate any unintentional boxing that will happen if a value type is passed to or returned from a method via its interface. The collection may still be enumerated in foreach statements (since the compiler uses pattern matching for that), but not elsewhere such as LINQ expressions.
Constructors
| OneOrMany<T>(Int32) |
Creates an instance of OneOrMany<T> that will use the given capacity to create its internal list. |
| OneOrMany<T>(List<T>) |
Creates an instance of OneOrMany<T> using the given list as the content. |
| OneOrMany<T>(T) |
Creates an instance of OneOrMany<T> using the given object as the content. |
Properties
| Comparer |
Gets or initializes the comparer to be used by Equals(Object) or GetHashCode(). |
| Count |
Returns the count of the number of elements in the collection. |
| Item[Int32] |
Gets the element at the specified index in the collection. |
Methods
| Add(T) |
Add a new value to the collection. |
| AsList() |
Returns the underlying list if this object contains > 1 item, otherwise null. |
| Equals(Object) | Indicates whether this instance and a specified object are equal. |
| GetEnumerator() |
Get an efficient enumerator for the collection |
| GetHashCode() | Returns the hash code for this instance. |
| RemoveAt(Int32) |
Remove the item at the specified index from the collection. |
