Learn about generic classes used in collections like linked lists, hash tables, stacks, queues, and trees.
We can use the type T to declare a generic data type in C#. It can be either used as a function return type or the data type of function parameters.
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。
Learn about generics. Generic types maximize code reuse, type safety, and performance, and are commonly used to create collection classes.

The Generic Multifunction PC-Card component provides support for a generic multifunction PC card device. This component includes the mf.sys file, which contains the system-supplied multifunction bus driver. This component also includes the mf.inf file, which is the system-supplied INF file for ...
error C2059:语法错误:'generic‘ 是一个编译错误,通常出现在C或C++代码中。该错误表示在代码中使用了无效的语法或关键字。 具体来说,'generic'是C++中的一个关键字,用于定义泛型编程中的模板。然而,在某些情况下,编译器可能无法识别'generic'关键字,导致出现语法错误。 要解决这个错误,可以尝试以下几个步骤: 检...
“Returns the size of an unmanaged type in bytes.”, it is not quite true today. Any enum is considered to be an unmanaged type but trying to use an enum type inMarshal.SizeOf<MyEnum>()will lead to a runtime error. For all other unmanaged types, this function works similar tosize...
