KeyValuePairCoda Class

⊟ Member Details

⊟ Aggregate<TKey,TValue,TResult> Generic Method

Applies an accumulator to a KeyValuePair<TKey, TValue>, converting the KeyValuePair<TKey, TValue> into a different value.

public static TResult Aggregate<TKey, TValue, TResult> (this KeyValuePair<TKey, TValue> self, Func<TKey, TValue, TResult> func)

⊟ Type Parameters

TKey

The type of the key.

TValue

Type type of the value.

TResult

The type to accumulator value.

⊟ Parameters

self

A KeyValuePair<TKey, TValue>. instance to convert into a TResult.

func

A Func<TKey, TValue, TResult> which is invoked to convert the KeyValuePair<TKey, TValue> into a TResult.

⊟ Returns

A TResult, which is the return value of func.

⊟ Exceptions

Type	Reason
ArgumentNullException	Documentation for this section has not yet been entered.

⊟ Remarks

This is useful primarily to avoid an unseemly temporary (or to more easily use KeyValuePair<TKey, TValue>s within expressions).

C# Example

var dict = new Dictionary<int, int> { { 1, 1 }, { 2, 4 }, { 3, 9 }, }; string entries = dict .Select( e => /* e is a KeyValuePair<int,int> */ e.Aggregate( (k, v) => string.Format("({0},{1})", k, v) ) ) .Implode("|"); // entries contains "(1,1)|(2,4)|(3,9)"

⊟ Requirements

Namespace: Cadenza.Collections
Assembly: Cadenza (in Cadenza.dll)
Assembly Versions: 0.1.0.0

⊟ ToTuple<TKey,TValue> Generic Method

Converts a KeyValuePair<TKey, TValue> into a Cadenza.Tuple<TKey, TValue>.

public static Cadenza.Tuple<TKey, TValue> ToTuple<TKey, TValue> (this KeyValuePair<TKey, TValue> self)

⊟ See Also

Cadenza.TupleCoda.ToKeyValuePair``2(Cadenza.Tuple<``0, ``1>)

⊟ Type Parameters

TKey

The type of the key.

TValue

The type of the value.

⊟ Parameters

self

A KeyValuePair<TKey, TValue>. to convert into a Cadenza.Tuple<TKey, TValue>.

⊟ Returns

A Cadenza.Tuple<TKey, TValue> struct.

⊟ Remarks

The value of the returned Cadenza.Tuple`2._1 property is copied from KeyValuePair`2.Key and the value of the returned Cadenza.Tuple`2._2 is copied from KeyValuePair`2.Value.

C# Example

KeyValuePair<string, int> kvp = new KeyValuePair<string, int> ("s", 1); Tuple<string, int> tuple = kvp.ToTuple (); // tuple._1 == "s", tuple._2 == 1
