元数据在 C# 代码生成中的应用主要体现在以下几个方面:
Type type = typeof(MyClass);
ConstructorInfo[] constructors = type.GetConstructors();
PropertyInfo[] properties = type.GetProperties();
MethodInfo[] methods = type.GetMethods();
[AttributeUsage(AttributeTargets.Class)]
public class MyCustomAttribute : Attribute
{
public string Description { get; set; }
}
[MyCustomAttribute(Description = "This is a custom attribute")]
public class MyClass
{
}
Type type = typeof(MyClass);
MyCustomAttribute attribute = (MyCustomAttribute)type.GetCustomAttributes(typeof(MyCustomAttribute), false)[0];
Console.WriteLine(attribute.Description);
System.Reflection.Emit
命名空间中的类来动态生成程序集、模块、类型和成员。AssemblyName assemblyName = new AssemblyName("DynamicAssembly");
AssemblyBuilder assemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.Run);
ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("DynamicModule");
TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicType", TypeAttributes.Public);
typeBuilder.DefineDefaultConstructor(MethodAttributes.Public);
Type dynamicType = typeBuilder.CreateType();
object instance = Activator.CreateInstance(dynamicType);
using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using Microsoft.CodeAnalysis.CSharp.Syntax;
string code = "class MyClass { void MyMethod() { } }";
SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(code);
CompilationUnitSyntax root = syntaxTree.GetRoot() as CompilationUnitSyntax;
ClassDeclarationSyntax classDeclaration = root.DescendantNodes().OfType<ClassDeclarationSyntax>().First();
MethodDeclarationSyntax methodDeclaration = classDeclaration.DescendantNodes().OfType<MethodDeclarationSyntax>().First();
Console.WriteLine($"Class: {classDeclaration.Identifier.ValueText}, Method: {methodDeclaration.Identifier.ValueText}");
总之,元数据在 C# 代码生成中的应用非常广泛,可以帮助开发人员更轻松地处理类型信息、自定义属性、代码生成和代码分析等任务。
