How to iterate all "public string" properties in a .net class

Question

Lets say I have some random .cs file containing a class with some properties and methods of all sorts.

How can I iterate the names (as strings) of all these public string properties?

Example.cs:

Public class Example
{
 public string FieldA {get;set;}
 public string FieldB {get;set;}
 private string Message1 {get;set;}
 public int someInt {get;set;}

 public void Button1_Click(object sender, EventArgs e)
 {
   Message1 = "Fields: ";
   ForEach(string propertyName in this.GetPublicStringProperties())
   {
     Message1 += propertyName + ",";
   } 
   // Message1 = "Fields: Field1,Field2"
 }

 private string[] GetPublicStringProperties()
 {
    //What do we put here to return {"Field1", "Field2"} ?
 }
}

Answer 1

You can use the GetProperties method of Type:

GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance);

This will give you an array of PropertyInfo objects, one for each property.

You can check the property is a string property by checking that:

property.PropertyType == typeof(string)

To get the names of the properties use property.Name.

Answer 2

private string[] GetPublicStringProperties()
{
    return this.GetType()
        .GetProperties(BindingFlags.Public | BindingFlags.Instance)
        .Where(pi => pi.PropertyType == typeof(string))
        .Select(pi => pi.Name)
        .ToArray();
}

Answer 3

var publicStringProperties = from property in GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance) where property.PropertyType == typeof(string) select property.Name;
