Is the method naming for property getters/setters standardized in IL?

Question

I have the following two methods that I am wondering if they are appropriate:

public bool IsGetter(MethodInfo method)
{
    return method.IsSpecialName
              


        

Answer 1

You could try the following:

public bool IsGetter(MethodInfo method)
{
    return method.DeclaringType.GetProperties().
                                Any(propInfo => propInfo.GetMethod == method);
}

You can optionally specify the binding flags for GetProperties

Answer 2

A property method has three extra characteristics, compared with a normal method:

1. They always start with get_ or set_, while a normal method CAN start with those prefixes.
2. The property MethodInfo.IsSpecialName is set to true.
3. The MethodInfo has a custom attribute System.Runtime.CompilerServices.CompilerGeneratedAttribute.

You could check on 1, combined with option 2 or 3. Since the prefixes are a standard, you should not really worry about checking on it.

The other method is to enumerate through all properties and match the methods, which will be much slower:

public bool IsGetter(MethodInfo method)
{
    if (!method.IsSpecialName)
        return false; // Easy and fast way out. 
    return method.DeclaringType
        .GetProperties(BindingFlags.Instance | BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic) 
        .Any(p => p.GetGetMethod() == method);
}
