Get all properties with values reflection

Question

I wrote custom property attribute and set it on couple of properties in my class. Now I would like during runtime get only properties which has this attribute, be able to get value of the property as well as values of attribute fields. Could You please help me with this task ? thanks for help

I'm fairly sure this is a duplicate, but haven't found a match. I did find the related [Check if property has attribute](http://stackoverflow.com/questions/2051065/check-if-property-has-attribute) and [Finding the attributes on the properties of an instance of a class](http://stackoverflow.com/questions/2999035/finding-the-attributes-on-the-properties-of-an-instance-of-a-class). — C.

Here's an example:

void Main()
{
    var myC = new C { Abc = "Hello!" };
    var t = typeof(C);
    foreach (var prop in t.GetProperties())
    {
        var attr = prop.GetCustomAttributes(typeof(StringLengthAttribute), true).Cast<StringLengthAttribute>().FirstOrDefault();
        if (attr != null)
        {
            var attrValue = attr.MaximumLength; // 100
            var propertyValue = prop.GetValue(myC, null); // "Hello!"
        }
    }
}
class C
{
    [StringLength(100)]
    public string Abc {get;set;}
}

You can use PropertyInfo.Attributes
