In C#, a Dictionary is a collection of key-value pairs that allows access and manipulation of values through keys. It is a generic type that can store keys and values of any type.<\/p>\n

Here are some common uses of the dictionary.<\/p>\n

    \n
  1. Create a Dictionary object:<\/li>\n<\/ol>\n
    Dictionary<TKey, TValue> dictionary = new<\/span> Dictionary<TKey, TValue>();\r\n<\/code><\/pre>\n
      \n
    1. Add a key-value pair:<\/li>\n<\/ol>\n
      dictionary.Add(key, value<\/span>);\r\n<\/code><\/pre>\n
      Alternatively, you could use an indexer.<\/p>\n
      dictionary[key] = value<\/span>;\r\n<\/code><\/pre>\n
        \n
      1. Get value:<\/li>\n<\/ol>\n
        TValue value<\/span> = dictionary[key];\r\n<\/code><\/pre>\n
          \n
        1. Check if it contains a specified key:<\/li>\n<\/ol>\n
          bool<\/span> containsKey = dictionary.ContainsKey(key);\r\n<\/code><\/pre>\n
            \n
          1. Get all keys or values.<\/li>\n<\/ol>\n
            ICollection<TKey> keys = dictionary.Keys;\r\nICollection<TValue> values = dictionary.Values;\r\n<\/code><\/pre>\n
              \n
            1. Iterating through a dictionary:<\/li>\n<\/ol>\n
              foreach<\/span> (KeyValuePair<TKey, TValue> pair in<\/span> dictionary)\r\n{\r\n    TKey key = pair.Key;\r\n    TValue value<\/span> = pair.Value;\r\n    \/\/ \u8fdb\u884c\u64cd\u4f5c<\/span>\r\n}\r\n<\/code><\/pre>\n
                \n
              1. Remove key-value pair:<\/li>\n<\/ol>\n
                bool<\/span> removed = dictionary.Remove(key);\r\n<\/code><\/pre>\n
                  \n
                1. clear the dictionary<\/li>\n<\/ol>\n
                  dictionary.Clear();\r\n<\/code><\/pre>\n
                  A Dictionary is an efficient data structure that allows for quick searching and manipulation of key-value pairs. It is widely used in many scenarios such as caching and indexing.<\/p>\n","protected":false},"excerpt":{"rendered":"
