- TKey

- TValue
The type of values in the read-only dictionary.

IEnumerable<KeyValuePair<TKey,TValue>> IEnumerable<T> IReadOnlyCollection<KeyValuePair<TKey,TValue>> IEnumerable
Remarks
Each element is a key/value pair that is stored in a KeyValuePair<TKey,TValue> object.
Each pair must have a unique key. Implementations can vary in whether they allow you to specify a key that is null. The value can be null and does not have to be unique. The IReadOnlyDictionary<TKey,TValue> interface allows the contained keys and values to be enumerated, but it does not imply any particular sort order.
The foreach statement of the C# language (For Each in Visual Basic, for each in C++) requires the type of each element in the collection. Because each element of the IReadOnlyDictionary<TKey,TValue> interface is a key/value pair, the element type is not the type of the key or the type of the value. Instead, the element type is KeyValuePair<TKey,TValue>, as the following example illustrates.
for each(KeyValuePair<int, String^> kvp in myDictionary)
{
Console::WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}
foreach (KeyValuePair<int, string> kvp in myDictionary)
{
Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}
For Each kvp As KeyValuePair(Of Integer, String) In myDictionary
Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value)
Next kvp
The foreach statement is a wrapper around the enumerator; it allows only reading from the collection, not writing to the collection.
