C＃编译器无法优化for循环，与foreach相同

string [] lines = TheRichTextBox.Lines; for（int i = 0; i< lines.Length; i ++） { Len + = lines [i] .Length; } 它应该类似于foreach案例。 DavidAh. It''s not a compiler problem. It''s a property problem.get_Lines() is expensive. Who Knew? That''s the problem with properties: younever know how much code they run.Anyway, try this:string[] lines = TheRichTextBox.Lines;for (int i = 0; i < lines.Length; i++){Len += lines[i].Length;}It should be similar to the foreach case.David 这篇关于C＃编译器无法优化for循环，与foreach相同的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
