GeneratedCodeAttribute Class

Definition

Identifies code generated by a tool. This class cannot be inherited.

public ref class GeneratedCodeAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.All, AllowMultiple=false, Inherited=false)]
public sealed class GeneratedCodeAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.All, AllowMultiple=false, Inherited=false)>]
type GeneratedCodeAttribute = class
    inherit Attribute
Public NotInheritable Class GeneratedCodeAttribute

Examples

The following code example shows the use of the GeneratedCodeAttribute class to identify computer-generated code.

#using <System.dll>
#using <System.Xml.dll>

using namespace System;
using namespace System::CodeDom;
using namespace System::CodeDom::Compiler;

int main()
{
    // Declare a new type called Class1.
    CodeTypeDeclaration^ class1 = gcnew CodeTypeDeclaration("Class1");

    // Declare a new generated code attribute
    GeneratedCodeAttribute^ generatedCodeAttribute =
        gcnew GeneratedCodeAttribute("SampleCodeGenerator", "2.0.0.0");

    // Use the generated code attribute members in the attribute declaration
    CodeAttributeDeclaration^ codeAttrDecl =
        gcnew CodeAttributeDeclaration(generatedCodeAttribute->GetType()->Name,
            gcnew CodeAttributeArgument(
                gcnew CodePrimitiveExpression(generatedCodeAttribute->Tool)),
            gcnew CodeAttributeArgument(
                gcnew CodePrimitiveExpression(generatedCodeAttribute->Version)));
    class1->CustomAttributes->Add(codeAttrDecl);

    // Create a C# code provider
    CodeDomProvider^ provider = CodeDomProvider::CreateProvider("CSharp");

    // Generate code and send the output to the console
    provider->GenerateCodeFromType(class1, Console::Out, gcnew CodeGeneratorOptions());
}

// The CPP code generator produces the following source code for the preceeding example code:
//
// [GeneratedCodeAttribute("SampleCodeGenerator", "2.0.0.0")]
// public class Class1 {
// }
using System;
using System.CodeDom;
using System.CodeDom.Compiler;

public class CodeGenExample
{
    static void Main()
    {
        // Declare a new type called Class1.
        CodeTypeDeclaration class1 = new CodeTypeDeclaration("Class1");

        // Declare a new generated code attribute
        GeneratedCodeAttribute generatedCodeAttribute =
            new GeneratedCodeAttribute("SampleCodeGenerator", "2.0.0.0");

        // Use the generated code attribute members in the attribute declaration
        CodeAttributeDeclaration codeAttrDecl =
            new CodeAttributeDeclaration(generatedCodeAttribute.GetType().Name,
                new CodeAttributeArgument(
                    new CodePrimitiveExpression(generatedCodeAttribute.Tool)),
                new CodeAttributeArgument(
                    new CodePrimitiveExpression(generatedCodeAttribute.Version)));
        class1.CustomAttributes.Add(codeAttrDecl);

        // Create a C# code provider
        CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");

        // Generate code and send the output to the console
        provider.GenerateCodeFromType(class1, Console.Out, new CodeGeneratorOptions());
    }
}

// The C# code generator produces the following source code for the preceeding example code:
//
// [GeneratedCodeAttribute("SampleCodeGenerator", "2.0.0.0")]
// public class Class1 {
// }

Imports System.CodeDom.Compiler

Public Class CodeGenExample

    Shared Sub Main
        ' Declare a new type called Class1.
        Dim class1 as New CodeTypeDeclaration("Class1")

        ' Declare a new generated code attribute
        Dim generatedCodeAttribute As _
            New GeneratedCodeAttribute("SampleCodeGenerator", "2.0.0.0")

        ' Use the generated code attribute members in the attribute declaration
        Dim  codeAttrDecl As _
            New CodeAttributeDeclaration(generatedCodeAttribute.GetType().Name,
                New CodeAttributeArgument(

                New CodeAttributeArgument(
                    New CodePrimitiveExpression(generatedCodeAttribute.Version)))
        class1.CustomAttributes.Add(codeAttrDecl)

        ' Create a Visual Basic code provider
        Dim provider As CodeDomProvider = CodeDomProvider.CreateProvider("VisualBasic")

        ' Generate code and send the output to the console
        provider.GenerateCodeFromType(class1, Console.Out, New CodeGeneratorOptions())
    End Sub

End Class

' Public Class Class1

Remarks

The GeneratedCodeAttribute class can be used by code analysis tools to identify computer-generated code, and to provide an analysis based on the tool and the version of the tool that generated the code.

Constructors

GeneratedCodeAttribute(String, String)

Initializes a new instance of the GeneratedCodeAttribute class specifying the name and version of the tool that generated the code.

Properties

Tool

Gets the name of the tool that generated the code.

TypeId

When implemented in a derived class, gets a unique identifier for this Attribute.

(Inherited from Attribute)
Version

Gets the version of the tool that generated the code.

Methods

Equals(Object)

Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)
GetHashCode()

Returns the hash code for this instance.

(Inherited from Attribute)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
IsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(Inherited from Attribute)
Match(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(Inherited from Attribute)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
ToString()

Returns a string that represents the current object.

(Inherited from Object)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.

(Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.

(Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.

(Inherited from Attribute)
