Get all properties which marked certain attribute

Posted by: admin November 30, 2017 Leave a comment


I have class and properties in there. Some properties can be marked attribute (it’s my LocalizedDisplayName inherits from DisplayNameAttribute).
This is method for get all properties of class:

private void FillAttribute()
    Type type = typeof (NormDoc);
    PropertyInfo[] propertyInfos = type.GetProperties();
    foreach (var propertyInfo in propertyInfos)

I want to add properties of class in the listbox which marked LocalizedDisplayName and display value of attribute in the listbox. How can I do this?

This is LocalizedDisplayNameAttribute:

public class LocalizedDisplayNameAttribute : DisplayNameAttribute
        public LocalizedDisplayNameAttribute(string resourceId)
            : base(GetMessageFromResource(resourceId))
        { }

        private static string GetMessageFromResource(string resourceId)
            var test =Thread.CurrentThread.CurrentCulture;
            ResourceManager manager = new ResourceManager("EArchive.Data.Resources.DataResource", Assembly.GetExecutingAssembly());
            return manager.GetString(resourceId);

I want to get string from resource file.


It’s probably easiest to use IsDefined:

var properties = type.GetProperties()
    .Where(prop => prop.IsDefined(typeof(LocalizedDisplayNameAttribute), false));

EDIT: To get the values themselves, you’d use:

var attributes = (LocalizedDisplayNameAttribute[]) 
      prop.GetCustomAttributes(typeof(LocalizedDisplayNameAttribute), false);
