在哪里可以使用顶级语句在.NET 6控制台模板中定义委托？
我最近尝试了带有顶级语句的.NET 6控制台模板，并在Visual Studio中偶然发现了A gotcha 。如果您尝试编译以下代码，Visual Studio将在字符串声明下给出一条红色的线条var s =“ mystring”;。您还将收到错误：顶级语句必须先于名称空间并键入声明。
delegate string StringReturner(int i);
var s = "myString";
Console.WriteLine(s);
因此，这里有什么问题？
I recently tried the .Net 6 console template, with top level statements, in Visual studio and stumbled into a Gotcha. If you try to compile the below code, Visual Studio will give a red squiggly line under the string declaration var s = "myString";. You will also receive the error: Top-level statements must precede namespace and type declarations.
delegate string StringReturner(int i);
var s = "myString";
Console.WriteLine(s);
So, what is the problem here?

问题在于，代表声明必须在顶级语句之后进行。代表声明不算为顶级语句，而是算作类型声明。以下代码正常：
The issue is that the delegate declaration has to happen after the top level statements. A delegate declaration does not count as a top level statement, but counts as a type declaration. The following code works fine:
