C# Iterative迭代用法代码，这是一个与 Iterative相关的代码，演示迭代的使用，思路和过程：创建一个string类型的数组用于存储银行种类，对IEnumerator接口实现GetEnumerator方法创建迭代器，使用for语句循环数组，使用yield return语句依次返回每个元素，实例化BankType类，使用foreach语句遍历BankType类中的内容并输出-C# Iterative iteration of usage code, which is associated with Iterative instance, demonstrates the use of iteration, ideas, and process: Create a string array for storing the types of banks GetEnumerator method to create an iterator IEnumerator interface, the use of the for loop array, using the yield return statement returned in turn each element instantiated BankType class, using the foreach statement the traversal BankType class content and output
