Reflection question

[Le Minh]

Hi all
I'm writing an application using reflection feature of .NET Framework.
My applicaiton need to accept a assembly name as input parameter and then
must populate all methods and property from all class in this.
I'm trying to use BindingFlags with GetMethods and GetProperties from
System.Type class but i can't apply correct BindingFlags.
I only need to get public property and public and static method.

Anyone can help me?
Many thanks.

Here is my sample code:
public static void GetAssembly(string sAssemblyName)
{
List<MethodInfo> methodList = new List<MethodInfo>();
List<PropertyInfo> propertyList = new List<PropertyInfo>();

Assembly asm = Assembly.LoadFrom(Environment.CurrentDirectory +
"\\" +sAssemblyName);

Type[] types = asm.GetTypes();
foreach (Type type in types)
{
MethodInfo[] methods =
type.GetMethods(BindingFlags.DeclaredOnly | BindingFlags.Public);
for (int i = 0; i < methods.Length; i++)
{
if (methods.IsPublic && methods.IsStatic &&
!methods.Name.StartsWith("Can"))
{
methodList.Add(methods);
}
}
PropertyInfo[] properties =
type.GetProperties(BindingFlags.DeclaredOnly | BindingFlags.Public);
for (int i = 0; i < properties.Length; i++)
{

}
MemberInfo[] members = type.FindMembers(MemberTypes.Method,
BindingFlags.Default, Type.FilterName, "Get*");
}
}

Hello,

Are you using Environment.CurrentDirectory an demand, cause this is going to
change if you are using an OpenFileDialog for example.

For the Usage of BindingFlags you could just read the docu:
For the publicProperties:
myType.GetProperties(BindingFlags.Public|BindingFlags.Instance);
For the static methods
myType.GetProperties(BindingFlags.Static);


The problem was that you have to use one of the two BindingFlags ( Instance
or Static) to get a result back.

All the best,

Martin

Thanks for your reply!

property is also returned.
How i can fix this problem?

What is the error you are getting?

At eye inspection the flags seems correct:
type.GetMethods(BindingFlags.DeclaredOnly | BindingFlags.Public);

Get the method declared in that type that are public.

So, what do you expect it to do?
Is it really a problem?

Thanks for your reply!
