This method does what it says
private static string[] getPropertiesOfClass(string ClassName, string ProjectName, object yourClassObject)
{
// Gets all Assemblies available in the current Project
AssemblyName[] referencedAssemblies = Assembly.GetExecutingAssembly().GetReferencedAssemblies();
/// Get all Assembly's Name
var referencedTypes = referencedAssemblies.SelectMany(x => Assembly.Load(x.FullName).GetTypes());
/// Declaring and Initializing a List
/// to store all Property's name
List _allPropertyNames = new List();
foreach (AssemblyName item in referencedAssemblies)
{
/// if Assembly name is the same as provided as Project Name
if (item.Name == ProjectName)
{
/// Finds the Project
Assembly _Assembly = GetAssemblyByName(item.Name);
if (_Assembly != null)
{
/// If project is found the converts its all types
/// present in the project to list
List type = _Assembly.ExportedTypes.ToList();
foreach (Type classType in type)
if (classType.Name == ClassName)
{
Type mytype = Type.GetType(classType.AssemblyQualifiedName);
object instance = Activator.CreateInstance(mytype);
instance = yourClassObject;
/// Gets all properties
/// and adds them in a list
PropertyInfo[] properties = classType.GetProperties();
foreach (PropertyInfo property in properties)
{
_allPropertyNames.Add(property.Name);
property.GetValue(instance);
}
}
}
}
}
return _allPropertyNames.ToArray();
}
