Class UnionContract

Describes a type with several known subtypes, each identified by a discriminator.

public sealed class UnionContract : DataContract

Inherited Members: DataContract.DataType

DataContract.ToString()

object.Equals(object)

object.Equals(object, object)

object.GetHashCode()

object.GetType()

object.ReferenceEquals(object, object)

Remarks

A union value is encoded as a two-element vector: the discriminator followed by the value. A null discriminator selects BaseType.

Initializes a new instance of the UnionContract class.

public UnionContract(Type dataType, DataContract baseType, IEnumerable<UnionCaseContract> cases)

Gets the contract used when the discriminator is null.

public DataContract BaseType { get; }

Gets the known cases of the union.

public ImmutableArray<UnionCaseContract> Cases { get; }

Gets the kind of this contract, which identifies the concrete subclass.

public override DataContractKind Kind { get; }

Gets the contracts that this contract directly refers to.

public override IEnumerable<DataContract> ReferencedContracts { get; }

The sequence may contain the same contract more than once, and (for recursive types) may transitively include this contract itself.
