Jun 21, 2018 Here, we will implement a menu drive program in C to generate random password with various combinations of alphabets and special characters. Submitted by Hritik Raj, on June 21, 2018.
Definition
Defines a key/value pair that can be set or retrieved.
Type Parameters
- TValue
The type of the value.
- Attributes
Examples
The following code example shows how to enumerate the keys and values in a dictionary, using the KeyValuePair<TKey,TValue> structure.
This code is part of a larger example provided for the Dictionary<TKey,TValue> class.
Remarks
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) returns an object of 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 KeyValuePair<TKey,TValue>. For example:
The foreach statement is a wrapper around the enumerator, which allows only reading from, not writing to, the collection.
Constructors
| KeyValuePair<TKey,TValue>(TKey, TValue) | Initializes a new instance of the KeyValuePair<TKey,TValue> structure with the specified key and value. |
Properties
| Key | Gets the key in the key/value pair. |
| Value | Gets the value in the key/value pair. |
Methods
| Deconstruct(TKey, TValue) | |
| ToString() | Returns a string representation of the KeyValuePair<TKey,TValue>, using the string representations of the key and value. |
