foreach( KeyValuePair<string, string> kvp in myDictionary ) { Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value); } foreach 語句是列舉值周圍的包裝函式,它只允許從集合讀取,而不是寫入集合。注意 因為索引鍵可以繼承並變更其行為,所以使用 Equals 方法的比較無法保證其絕對唯一性...

foreach( KeyValuePair<string, string> kvp in myDictionary ) { Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value); } foreach 语句是枚举器周围的包装器,它只允许从集合中读取,而不是写入集合。备注 由于可以继承密钥并更改其行为,因此使用 Equals 方法的比较无法保证其绝对唯一性。
