How to retrive Property Name using DisplayName?

Question

public class DoctorInfo    
{
     [DisplayName("form1[0].P1[0].Physician-Name[0]")]
     public string ProviderFullName { get; set; }
}

How can i get Property Name "ProviderFullName" programmatically if i have its DisplayName in hand?

Answer 1

Given the DisplayName you can get all the PropertyInfo members in the class, then iterate over those to see if any of those has a DisplayName attribute using MemberInfo.GetCustomAttributes .

If the DisplayName matches, then use the MemberInfo.Name property to get the name back.

Answer 2

you can iterate the properties and custom attributes -

 PropertyInfo[] properties = typeof(DoctorInfo).GetProperties();
            foreach (PropertyInfo prop in properties)
            {
                object[] attrs = prop.GetCustomAttributes(true);

                foreach (object attr in attrs)
                {
                    DisplayNameAttribute displayName = attr as DisplayNameAttribute;
                    if (displayName != null)
                    {
                       var attributeName = displayName.DisplayName; // check if this matches what you want
                    string propertyName = prop.Name;                        }
                }
            }
