Voorbeelden

In het volgende codevoorbeeld ziet u het gebruik van de klasse om door de GeneratedCodeAttribute computer gegenereerde code te identificeren.

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 {

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 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

Opmerkingen

De GeneratedCodeAttribute klasse kan worden gebruikt door hulpprogramma's voor codeanalyse om door de computer gegenereerde code te identificeren en om een analyse te bieden op basis van het hulpprogramma en de versie van het hulpprogramma dat de code heeft gegenereerd.
