什么是java中的@Deprecated的.NET等价物？

Question

.NET中是否有注释允许方法或类被弃用，以便编译器识别它们的使用和调用者（参见Java中的@Deprecated）

Answer 1

The [Obsolete] attribute.

You can add a comment on what people should be using, for example:

[Obsolete("Use NewMethod() instead")]
public void OldMethod()
{
}

If you want to generate a compiler error when people use your method:

[Obsolete("Use NewMethod() instead", true)]
public void OldMethod()
{
}

This is an example for a method, but it can be used on almost any attribute target. See here for full docs.

Since the question was edited slightly, I'll add the VB.NET syntax as well, to cover the most common .NET languages:

<Obsolete("Use NewMethod() instead")> _
Public Sub OldMethod()
End Sub

Answer 2

[Obsolete] - see here for documentation on it. Adding this to a method or class will give a compiler warning if anyone tries to use it, with the custom message you give to the attribute if needed
