GetRuntimeProperties instead of GetProperty

Question

I need to find property inside of generic type. This is an old way (and since my code is dedicated for WinRT I believe I need another approach):

PropertyInfo pi = typeof(TRp).GenericTypeArguments[0].GetProperty(idField, BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance);  

I need to achieve the same result using GetRuntimeProperties. This is my approach:

PropertyInfo pi = typeof(TRp).GenericTypeArguments[0].GetRuntimeProperties().Single(p => p.Name.ToUpper() == idField.ToUpper()...  

as you can see I implemented IgnoreCase in a custom way, probably it can be done better?
How can I implement remaining BindingFlags?

Thank you!

You actually dont need to. This is how Type.GetRuntimeProperties is implemented:

public static IEnumerable<PropertyInfo> GetRuntimeProperties(this Type type)
{
    CheckAndThrow(type);

    IEnumerable<PropertyInfo> properties = type.GetProperties(everything);
    return properties;
}

Where everything is defined as following:

private const BindingFlags everything = BindingFlags.Instance |
                                        BindingFlags.Public | 
                                        BindingFlags.NonPublic | 
                                        BindingFlags.Static;

Which means it will already look for your required flags.

Edit:

If you want to specify BindingFlags yourself, you can write your own custom extension method:

public static class TypeExtensions
{
    public static IEnumerable<PropertyInfo> GetAllProperties(this TypeInfo type, 
                                                             BindingFlags bindingFlags)
    {
        var propertyInfos = type.GetProperties(bindingFlags);

        var subtype = type.BaseType;
        if (subtype != null)
            list.AddRange(subtype.GetTypeInfo().GetAllProperties(bindingFlags));

        return propertyInfos.ToArray();
    }
}

Note this hasn't been tested. It is merely an attempt to show you that you can do it yourself.
