驗證xml作爲針對xsd的內存流爲字符串

Question

我想驗證xml針對XSD（VB.NET）。我的功能是這樣的：

​​

我該怎麼辦時，我的XML是一個MemoryStream /流驗證（我用的流，因爲我並不需要存儲的XML）和我的XSD是一個字符串（我從Web服務獲得我的xsd作爲一個字符串，我不需要將它存儲在一個文件中）？

非常感謝您的幫助！

也許是這樣的。

Imports System.Xml 
Imports System.IO 
Imports System.Xml.Schema 

Module Module1 

    Private isvalid As Boolean 

    Sub Main() 
     Dim xml As MemoryStream 
     Dim xsd As String 
     Dim settings As New XmlReaderSettings() 
     settings.ValidationType = ValidationType.Schema 
     settings.Schemas.Add("Schema:name", xsd) 
     AddHandler settings.ValidationEventHandler, AddressOf MyValidationEventHandler 

     Dim v = XmlReader.Create(xml, settings) 

     While (v.Read()) 

     End While 

     If isValid Then 
      Console.WriteLine("Document is valid") 
     Else 
      Console.WriteLine("Document is invalid") 
     End If 
    End Sub 



    Public Sub MyValidationEventHandler(ByVal sender As Object, ByVal args As ValidationEventArgs) 
     isValid = False 
     Console.WriteLine("Validation event\n" + args.Message) 
    End Sub 
End Module
