I'm a new to xml serialization and I haven't found much joy on the web.
How do i specify arbthree both nullable and a nonNegativeInteger? Or in otherwords have more then 1 attribute type?
i tried using them together like the following but I get a compile error
[System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
[System.Xml.Serialization.XmlElementAttribute(DataType="nonNegativeInteger")]
public string arbtwo;
[System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
public string arbone;
[System.Xml.Serialization.XmlElementAttribute(DataType="nonNegativeInteger")]
public string arbtwo;
public string arbthree;

In the code you posted above, it is correct to apply multiple attributes above the item such as your first example. If the entire example you have above is all in one class, that could be your problem. You are defining arbtwo twice.
I tried this but of code and it compiled with no errors:
<code>
[System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
public string arbone;
[System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
[System.Xml.Serialization.XmlElementAttribute(DataType="nonNegativeInteger")]
public string arbtwo;
[System.Xml.Serialization.XmlElementAttribute(DataType="nonNegativeInteger")]
public string arbthree;
</code>

Sorry it does compile but I get a runtime error.
You need to add XmlChoiceIdentifierAttribute to the 'arbtwo' member.

Well the syntax of the attribute tags is correct, so your code is not compiling for another reason. Can you paste some more of the code here so we can figure out why it's not?

I copied and pasted everything you have here into a new class in my .NET environment and it compiled perfectly 
|

It compiles fine.
Its giving me a runtime error when I goto the webservice.

You need to add XmlChoiceIdentifierAttribute to the 'InputValue' member.

Ahhh that makes sense. Well, just out of curiosity, did you do exactly what the error tells you to do? It's not done in the example you pasted. Add the XmlChoiceIdentifierAttribute to the InputValue member See below:
<code>
public class InputDetail
{
[System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
[System.Xml.Serialization.XmlElementAttribute(DataType="nonNegativeInteger")]
[System.Xml.Serialization.XmlChoiceIdentifierAttribute]
public int InputValue;
public InputDetail()
{
}
}
</code>

I still get a runtime exception.

|

Well silly, paste the new exception. It's probably a different exception than before. We'll work them out one by one.

There's the System.Net.Dns class that can be used to resolve the name.

Perhaps looking into the Directory[^] and File[^] classes would help. Each has methods for enumerating, copying, and deleteing folders and files.

Check out the cool HTM file that is located in the Exchange SDK. It is called webdavsample.htm. It does all that you are asking for. Look in the SDK/SAMPLES folder.

You want to retrieve the entire list of accessible files and folders based on a users ACL, correct? There is no function that will do this. You have to walk the filesystem tree and check each one individually.
