Regex C# - 如何匹配类的方法和属性名称 [英] Regex C# - how to match methods and properties names of a class

问题描述

我想匹配方法名称(带参数)和属性名称.我不想在匹配中包含访问器.例如我有这样的课程:

I want to match methods name (with parameters) and properties name. I dont want to include accessors in match. For example i got this kind of class:

public class test
{
    public static string NA = "n/a";

    public static DateTime DateParser(string dateToBeParsed)
    {
        DateTime returnValue = new DateTime();
        DateTime.TryParse(dateToBeParsed, GetCulture(), System.Globalization.DateTimeStyles.AssumeLocal , out returnValue);
        return returnValue;
    }
}

对于类名，我正在使用这种正则表达式:(?<=class\s)[^\s]+ 对于我正在尝试这样的方法:[^\s]+(?=() 但这将选择所有具有 ( 的文本.对于方法，我需要选择具有 ( 和访问器，如 public、private 和 protected.如何在不将其包含在最终匹配中的情况下执行此操作?我只需要括号内的方法名称和参数.

For class name I'm using this kind of regex: (?<=class\s)[^\s]+ for methods im trying something like this: [^\s]+(?=() but this will select all that text that has (. For methods i need to select that line that has ( and accessors like public,private and protected. How to do it without including this in final match ? I need only method name and parameters within parenthesis.

如何使用反射?

class Program
{
    static void Main(string[] args)
    {
        string assemblyName = Path.Combine(Path.GetTempPath(), string.Format("temp{0}.dll", Guid.NewGuid()));
        CSharpCodeProvider codeProvider = new CSharpCodeProvider();
        CompilerParameters compilerParameters = new CompilerParameters(new string[]
        {
            "System.dll",
            "Microsoft.CSharp.dll",
        }, assemblyName);

        CompilerResults cr = codeProvider.CompileAssemblyFromSource(compilerParameters, File.ReadAllText("Program.cs"));

        if (cr.Errors.Count > 0)
        {
            foreach (CompilerError error in cr.Errors)
            {
                Console.WriteLine(error.ErrorText);
            }
        }
        else
        {
            AppDomain appDomain = AppDomain.CreateDomain("volatile");
            Proxy p = (Proxy)appDomain.CreateInstanceAndUnwrap(Assembly.GetExecutingAssembly().FullName, typeof(Proxy).FullName);
            p.ShowTypesStructure(assemblyName);
            AppDomain.Unload(appDomain);
            File.Delete(assemblyName);
        }
        Console.ReadLine();
    }
}

public class Proxy : MarshalByRefObject
{
    public void ShowTypesStructure(string assemblyName)
    {
        Assembly assembly = Assembly.LoadFrom(assemblyName);
        Type[] types = assembly.GetTypes();
        foreach (Type type in types)
        {
            Console.WriteLine(type.Name);
            MethodInfo[] mis = type.GetMethods();
            foreach (MethodInfo mi in mis)
            {
                Console.WriteLine("\t" + mi.Name);
            }
        }
    }
}
