GeneratedCodeAttribute 类

定义

命名空间:

标识由工具生成的代码。 此类不能被继承。

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
Inherits Attribute

继承

GeneratedCodeAttribute

属性

示例

下面的代码示例演示如何使用 GeneratedCodeAttribute 类来标识计算机生成的代码。

#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
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 CodePrimitiveExpression(generatedCodeAttribute.Tool)),
                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

' The Visual Basic code generator produces the following source code for the preceeding example code:
'
' <GeneratedCodeAttribute("SampleCodeGenerator", "2.0.0.0")>  _
' Public Class Class1
' End Class

注解

GeneratedCodeAttribute代码分析工具可以使用 类来标识计算机生成的代码，并根据生成代码的工具和工具版本提供分析。

构造函数

GeneratedCodeAttribute(String, String)

初始化 GeneratedCodeAttribute 类的新实例，并在初始化时指定生成代码的工具的名称和版本。

属性

Tool	获取生成代码的工具的名称。
TypeId	在派生类中实现时，获取此 Attribute 的唯一标识符。 (继承自 Attribute)
Version	获取生成代码的工具的版本。

方法

Equals(Object)	返回一个值，该值指示此实例是否与指定的对象相等。 (继承自 Attribute)
GetHashCode()	返回此实例的哈希代码。 (继承自 Attribute)
GetType()	获取当前实例的 Type。 (继承自 Object)
IsDefaultAttribute()	在派生类中重写时，指示此实例的值是否是派生类的默认值。 (继承自 Attribute)
Match(Object)	当在派生类中重写时，返回一个指示此实例是否等于指定对象的值。 (继承自 Attribute)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示当前对象的字符串。 (继承自 Object)
