Cache, callback and nested class :)

 

 

using System;
using System.IO;
using System.Xml;
using System.Xml.Schema;

namespace xxx.WebService

One instance of this class will be pushed into cache and everyone can access it. It means that field validateResult is just like a static field. Suppose that A just call Validate() and validateResult is false. After that, B call this method again with a valid xml string, what B get now?  False

 Add a nest class:

class ValidateCallback
    }

Remove validateResult and add:

//Set the validation event handler
                ValidateCallback callback = new ValidateCallback();
                vReader.ValidationEventHandler += new ValidationEventHandler(callback.ValidationCallBack);
                //Read and validate the XML data.
                while (vReader.Read() && callback.ValidateResult);

Everyone can get his own result.
