Type.GetProperties Method (BindingFlags)

public abstract PropertyInfo[] GetProperties(
	BindingFlags bindingAttr
)

Implements

A property is considered public to reflection if it has at least one accessor that is public. Otherwise the property is considered private, and you must use BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static (in Visual Basic, combine the values using Or) to get it.

The GetProperties method does not return properties in a particular order, such as alphabetical or declaration order. Your code must not depend on the order in which properties are returned, because that order varies.

The following BindingFlags filter flags can be used to define which nested types to include in the search:

• You must specify either BindingFlags.Instance or BindingFlags.Static in order to get a return.

• Specify BindingFlags.Public to include public properties in the search.

• Specify BindingFlags.NonPublic to include non-public properties (that is, private, internal, and protected properties) in the search. Only protected and internal properties on base classes are returned; private properties on base classes are not returned.

• Specify BindingFlags.FlattenHierarchy to include public and protected static members up the hierarchy; private static members in inherited classes are not included.

The following BindingFlags modifier flags can be used to change how the search works:

• BindingFlags.DeclaredOnly to search only the properties declared on the Type, not properties that were simply inherited.

See System.Reflection.BindingFlags for more information.

A property is considered public to reflection if it has at least one accessor that is public. Otherwise the property is considered private, and you must use BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static (in Visual Basic, combine the values using Or) to get it.

If the current T:System.Type represents a constructed generic type, this method returns the PropertyInfo objects with the type parameters replaced by the appropriate type arguments.

If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the properties of the class constraint.

The following example creates two public properties and one protected property and displays information for the properties that match the specified binding constraints.

// Create a class having three properties.
public class MyTypeClass
{
    public String MyProperty1

    {
        get

        }
    }
    protected String MyProperty3
    {
        get
        {
            return "hello";
        }
    }
}

public class TypeMain
{
    public static void Main() 
    {
        Type myType =(typeof(MyTypeClass));
        // Get the public properties.
        PropertyInfo[] myPropertyInfo = myType.GetProperties(BindingFlags.Public|BindingFlags.Instance);
        Console.WriteLine("The mumber of public properties is {0}.", myPropertyInfo.Length);
        // Display the public properties.
        DisplayPropertyInfo(myPropertyInfo);
        // Get the nonpublic properties.
        PropertyInfo[] myPropertyInfo1 = myType.GetProperties(BindingFlags.NonPublic|BindingFlags.Instance);
        Console.WriteLine("The number of protected properties is {0}.", myPropertyInfo1.Length);
        // Display all the nonpublic properties.
        DisplayPropertyInfo(myPropertyInfo1);		
    }
    public static void DisplayPropertyInfo(PropertyInfo[] myPropertyInfo)
    {
        // Display information for all properties.
        for(int i=0;i<myPropertyInfo.Length;i++)
        {
            PropertyInfo myPropInfo = (PropertyInfo)myPropertyInfo[i];
            Console.WriteLine("The property name is {0}.", myPropInfo.Name);
            Console.WriteLine("The property type is {0}.", myPropInfo.PropertyType);
