This documentation is archived and is not being maintained. 17.4.3 The Obsolete attribute Visual Studio .NET 2003 The attribute Obsolete is used to mark types and members of types that should no longer be used. Copy namespace System { [AttributeUsage( AttributeTargets.Class | AttributeTargets.Struct | AttributeTargets.Enum c# warning attribute | AttributeTargets.Interface | AttributeTargets.Delegate | AttributeTargets.Method | AttributeTargets.Constructor | AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Event, Inherited = false) ] public class ObsoleteAttribute: Attribute { public ObsoleteAttribute() {...} public ObsoleteAttribute(string message) {...} public ObsoleteAttribute(string message, bool error) {...} public string Message { get {...} } public bool IsError { get {...} } } } If a program uses a type or member that is decorated with the Obsolete attribute, the compiler issues a warning or an error. Specifically, the compiler issues a warning if no error parameter is provided, or if the error parameter is provided and has the value false. The compiler issues an error if the error parameter is specified and has the value true. In the example Copy [Obsolete("This class is obsolete; use class B instead")] class A { public void F() {} } class B { public void F() {} } class Test { static void Main() { A a = new A(); // Warning a.F(); } } the class A is decorated with the Obsolete attribute. Each use of A in Main results in a warning that includes the specified message, "This class is obsolete; use

The second, a method named CallOldMethod, produces a compiler error. The example uses reflection to get information about the ObsoleteAttribute attributes applied to members of the type and displays the values of their Message and IsError properties.

The fact that using the KnownType attribute with a type that is marked with the Obsolete attribute and is causing a compiler warning is expected. However, in our project we have warnings treated as errors so ignoring the warning isn't an obsolete attribute example option. Is there a compiler directive to suppress this warning? The following usage causes a compiler warning: ///ProductTemplateDataSet is marked with the Obsolete attribute [KnownType(typeof(ProductTemplateDataSet))] public class EntityCollectionBase : System.Data.DataSet { } Edit: I understand using compiler directives to ignore errors, but this compiler warning doesn't have a number. c# .net attributes compiler-warnings share|improve this question edited Mar 11 '11 at 15:54 asked Mar 11 '11 at 15:46 Jace Rhea 3,74522352 Possible duplicate of C# - Selectively suppress custom Obsolete warnings –Kira Apr 14 at 11:56 add a comment| 3 Answers 3 active oldest votes up vote 79 down vote accepted Use this to disable the corresponding warnings just before the offending line: #pragma warning disable 612, 618 And reenable the warnings after it: #pragma warning restore 612, 618 Curiously enough, there're 2 warnings related to this: CS0612 and CS0618 - one is for [Obsolete] and the other for [Obsolete("Message")].

Unfortunately the property the API wants me to use is used by TFS2010 and not TFS2008. I have tried doing this: #pragma warning disable 0612, 0618 request.CommandLineArguments = arguments; #pragma warning restore 0612, 0618 But I still get the error that CommandLineArguments is obsolete. Is there anyway to suppress this? EDIT Unfortunately this is not showing up as a 'Warning as Error', in fact Treat Warning's As Error's is turned off in my project. Here is a screen cap of the offending code as well as the error list EDIT 2: After using ILSpy the CommandLineArguments property looks like this in the TFS2010 API: [Obsolete("This property has been deprecated. Please remove all references. To pass command line arguments to MSBuild.exe, set the ProcessParameters property.", true)] string CommandLineArguments { get; set; } Unfortunately I don't think there is a way to tell the compiler to ignore the error that the Obsolete attribute is causing. EDIT 3 As @Peter Ritchie points out this value could be set via reflection. As I thought through this problem though my guess is that if Microsoft set the property to throw an exception even if you did set it via reflection I doubt that the value would be referenced anywhere. c# share|improve this question edited May 16 '12 at 13:55 asked May 15 '12 at 20:22 abszero 1,39411531 I've just tested those two #pragma to suppress a custom cla
