我尝试了解一些旧的 VBA 代码的作用(以及如何作用)。
我有一个Sub,并且我有一个未在该Sub中声明的变量。
设置Option Explicit为False。
我应该将该变量视为全局变量吗?在 VBA 文档中没有找到该信息...
Sub test1()
x = "test one"
End Sub
Sub test2()
x = "test2"
Call test1
MsgBox (">'" + x + "'<")
End Sub

有没有一种方法(工具或其他东西)允许在从基类继承/重写方法时不重复相同的XML注释?
例如.:
/// <summary>
/// Represent a brand new object in .NET
/// </summary>
public class MyObject : Object
{
/// <summary>
/// Copy-Paste the same Xml comment
/// like in the base class is boring!
/// </summary>
/// <param name="obj">and params too!! ((</param>
/// <returns>this one too!!! (((</returns>
public override bool Equals(object obj)
{
return base.Equals(obj);
}
