C# - 有选择地抑制自定义过时警告

C# - Selectively suppress custom Obsolete warnings

提问by Alex

I'm using the Obsoleteattribute (as just suggested by fellow programmers) to show a warning if a certain method is used.

Obsolete如果使用某种方法，我正在使用该属性（正如其他程序员所建议的那样）来显示警告。

Is there a way to suppress the warning similar to CodeAnalysis' SuppressMessageat points where the use is justified?

有没有办法SuppressMessage在使用合理的地方抑制类似于 CodeAnalysis 的警告？

Thank you!

谢谢！

This is for [Obsolete("Some message")]as I need to include some details about the warning. However, #pragma warning disable 612doesn't work anymore once I add the message to the naked [Obsolete]attribute...

这是[Obsolete("Some message")]因为我需要包含有关警告的一些详细信息。但是，#pragma warning disable 612一旦我将消息添加到裸[Obsolete]属性就不再起作用......

Found the right warning number - It is 618if you have a message following the obsolete attribute.

找到正确的警告编号 -如果您在 obsolete 属性后面有一条消息，则为618。

So to do what I want to do:

所以做我想做的事：

#pragma warning disable 618

#pragma warning disable 618

and then after the call

然后在通话后

#pragma warning restore 618

#pragma warning restore 618

Thanks to Jared Par and Jon Skeet for pointing me in the right direction!

感谢 Jared Par 和 Jon Skeet 为我指明了正确的方向！

Use #pragma warning disable:

使用#pragma warning disable：

using System;

class Test
{
    [Obsolete("Message")]
    static void Foo(string x)
    {
    }

    static void Main(string[] args)
    {
#pragma warning disable 0618
        // This one is okay
        Foo("Good");
#pragma warning restore 0618

        // This call is bad
        Foo("Bad");
    }
}

Restore the warning afterwards so that you won't miss "bad" calls.

之后恢复警告，这样您就不会错过“坏”电话。

You're looking for the #pragmawarning disable directive

您正在寻找#pragma警告禁用指令

Essentially you add the following command above the call site in the .cs file.

本质上，您在 .cs 文件中的调用站点上方添加以下命令。

#pragma warning disable 612
SomeMethodCall

612 is the error message ID for calling obsolete methods

612 是调用过时方法的错误消息 ID

The intentis to disable the warning for obsolete usage, regardless of whether the construct is marked with [Obsolete]or [Obsolete("Message")]. So use both CS0612andCS0618:

该意图是禁用过时警告使用，无论是否结构标有[Obsolete]或[Obsolete("Message")]。所以同时使用CS0612和CS0618：

#pragma warning disable 612, 618 

...

#pragma warning restore 612, 618

Here's how to get the warning/error numberin the first place:

以下是首先获取警告/错误编号的方法：

1. Rebuildyour project.
2. Go to the Outputwindow.
3. Look up the line of the warning/error you want to suppress.
   For example:
   C:\Users\Username\Documents\Visual Studio 2010\Projects\Projectname\Classname.cs(203,7): warning CS0162: Unreachable code detected
4. Copy the number part after"CS".
5. Then proceed as Jon Skeet says.

1. 重建你的项目。
2. 转到输出窗口。
3. 查找要抑制的警告/错误行。
   例如：
   C:\Users\Username\Documents\Visual Studio 2010\Projects\Projectname\Classname.cs(203,7): warning CS0162: Unreachable code detected
4. 复制“ ”后的数字部分CS。
5. 然后按照 Jon Skeet所说的进行。
