How to get fields and their values from a static class in referenced assembly

Question

I have a static class in a refrenced assembly(named "DAL") named "A7":

A7 like this:

public static class A7
{
public static readonly bool NeedCoding = false;
public static readonly string Title = "Desc_Title"
public static readonly string F0 = "";
public static readonly string F1 = "Desc_F1";
public static readonly string F2 = "Desc_F2";
public static readonly string F3 = "Desc_F3";
public static readonly string F4 = "Desc_F4";
}

How I can get All Properties name and values from DAL assemby A7 class?

thanks

Using reflection, you will need to look for fields; these are not properties. As you can see from the following code, it looks for public static members:

class Program
{
    static void Main(string[] args)
    {
        Type t = typeof(A7);
        FieldInfo[] fields = t.GetFields(BindingFlags.Static | BindingFlags.Public);

        foreach (FieldInfo fi in fields)
        {
            Console.WriteLine(fi.Name);
            Console.WriteLine(fi.GetValue(null).ToString());
        }

        Console.Read();
    }
}

I faced the same issue when i tried to get the properties using this syntax (where "ConfigValues" is a static class with static properties and I am looking for a property with the name "LookingFor")

PropertyInfo propertyInfo = ConfigValues.GetType().GetProperties().SingleOrDefault(p => p.Name == "LookingFor");

The solution was to use the typeof operator instead

PropertyInfo propertyInfo = typeof(ConfigValues).GetProperties().SingleOrDefault(p => p.Name == "LookingFor");

that works, you don't have to view them as fields

See this or this question.

As you will notice in the first question, you also mix up properties and fields. What you are declaring are fields, not properties

So a variant of this should work:

Type myType = typeof(MyStaticClass);
FieldInfo[] fields= myType.GetFields(
       BindingFlags.Public | BindingFlags.Static | BindingFlags.DeclaredOnly);
foreach (FieldInfo f in fields)
{
    // use f.Name and f.GetValue(null) here
}

Solution 4

somthing like this: ?

FieldInfo[] fieldInfos = typeof(A7).GetFields(BindingFlags.Static | BindingFlags.Public);

Solution 5

 public static IEnumerable<T> GetAll<T>() where T : class
    {
      var fields = typeof(T).GetFields(BindingFlags.Public | BindingFlags.Static | BindingFlags.DeclaredOnly);
       return fields.Select(f => f.GetValue(null)).Cast<T>();
    }
