KeyValuePair<TKey, TValue> Structure
Defines a key/value pair that can be set or retrieved.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|Equals||Indicates whether this instance and a specified object are equal. (Inherited from ValueType.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from ValueType.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string representation of the , using the string representations of the key and value. (Overrides ValueType::ToString().)|
The Dictionary<TKey, TValue>::Enumerator::Current property returns an instance of this type.
The foreach statement of the C# language (for each in C++, For Each in Visual Basic) requires the type of the elements in the collection. Since each element of a collection based on IDictionary<TKey, TValue> 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 . For example:
The foreach statement is a wrapper around the enumerator, which allows only reading from, not writing to, the collection.
The following code example shows how to enumerate the keys and values in a dictionary, using the structure.
This code is part of a larger example (the second example) provided for the Dictionary<TKey, TValue> class.
