ResultTransfer主要用于对IEnumerable<IEnumerable<string>>结构的解析,另外还可以指定params string[] propertyNames属性参数列表来确定解析顺序(也即是属性顺序),主要方法如下: public static IList<T> Parse<T>(IEnumerable<IEnumerable<string>> entityRows, params string[] propertyNames) where T : new() 第一个...
在C#编程中,`string[]`和`IEnumerable<string>`都是表示字符串集合的数据类型,但它们之间存在一些差异。 1. 数据结构:`string[]`表示一个字符串数组,它是一个...

我们也可以通过ToBlockingEnumerable()方法将对应的IAsyncEnumerable<int>的结果转为同步阻塞的IEnumerable<T> // 通过 ToBlockingEnumerable 转为同步阻塞的 IEnumerable<T>varresult = GetNumbersAsync().ToBlockingEnumerable();// 将以同步代码执行Console.WriteLine($"当前线程:{Environment.CurrentManagedThreadId}")...
