C# - Disable CS0444 warning

I've this warning because I've created the type :

#if COMPACT_FRAMEWORK_3_5

namespace System.Diagnostics
{
    /// <summary>Determines how a class or field is displayed in the debugger variable windows.</summary>
    /// <remarks>See : http://msdn.microsoft.com/en-us/library/system.diagnostics.debuggerdisplayattribute.aspx </remarks>
    [AttributeUsage(AttributeTargets.Delegate | AttributeTargets.Field | AttributeTargets.Property | AttributeTargets.Enum | AttributeTargets.Struct | AttributeTargets.Class | AttributeTargets.Assembly, AllowMultiple = true)]
    [ComVisible(true)]
    public sealed class DebuggerDisplayAttribute : Attribute
    { /* ... */ }
}
#endif

I've created it because I'm on CF.NET and this attribute doesn't exists in it, so I created it in开发者_JS百科 order to customize my debug view (I always debug using CF.NET).

I've tried to add #pragma warning disable at the beginning and restore it at the end but doesn't work, I've always a CS0444 warning in VS2k8 ...

How can I fix this?

Thanks

EDIT

I used it like this :

#if COMPACT_FRAMEWORK_3_5
#pragma warning disable // 0444

namespace System.Diagnostics
{
    /// <summary>Determines how a class or field is displayed in the debugger variable windows.</summary>
    /// <remarks>See : http://msdn.microsoft.com/en-us/library/system.diagnostics.debuggerdisplayattribute.aspx </remarks>
    [AttributeUsage(AttributeTargets.Delegate | AttributeTargets.Field | AttributeTargets.Property | AttributeTargets.Enum | AttributeTargets.Struct | AttributeTargets.Class | AttributeTargets.Assembly, AllowMultiple = true)]
    [ComVisible(true)]
    public sealed class DebuggerDisplayAttribute : Attribute
    { /* ... */ }
}
#pragma warning restore // 0444
#endif

Your example has the number commented out:

#pragma warning disable // 0444

Eh, don't:

#pragma warning disable 444

To disable it globally, you use /nowarn:444 (comma-separate other warnings to disable) with the compiler. If using an IDE there'll probably be somewhere in the project properties to set warnings to disable (Visual Studio has it on the "Build" tab, SharpDevelop has it on the "Compiling" tab, other IDEs will likely have it somewhere similar). Nant scripts have a <onwarn> element as an allowed child of <csc> (which also has a nowarn attribute, but that's deprecated).

I'd avoid global disabling though, after all, doing something that triggers CS0444 is normally a bad idea. In your case above you've a good reason for doing so (you need functionality the compact version doesn't give you) and know that's what you are doing, but if you'd accidentally done it somewhere else, and you'd suppressed warnings, you'll be none the wiser.

Edit: For that matter, I've a policy that I never disable a warning without at least a short comment as to why. An uncommented disabling of a warning can mean "I did something silly here, and then disabled the warning rather than fixed it", the comment can make it clear that this isn't the case, and that there's nothing in need of a fix.

Ermm, perhaps try

#pragma warning disable 444

instead of commenting the error number? See here of course
