推荐答案

您创建数组的语法是错误的。你必须使用 [] ，而不是（）：

Your syntax of creating arrays is wrong. You have to use [], not ():

string[] createText = { "Hello", "Reading and writing text file" };

此外，您似乎将方法直接放在命名空间中。你不能这样做;方法必须放在一个类中。我想你的意思是将它们放在你的web表单的类中（使用命名空间查看，看起来你使用web表单）。

Also, it appears that you are putting methods directly in a namespace. You cannot do that; methods have to be put in a class. I suppose you meant to put them in the class of your web form (looking at your using namespaces it appears that you use web forms).
