-大家知道，用dataset传递的WebService，微软会在各个节点加上schema,所以无法和j2ee，flash兼容，所以我找到了一种转换他们变成普通xml的方法。代码如下： 方法一：Public Class DataSetToXML : Inherits System.Web.UI.Page
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim objConn As SqlConnection Dim strSql As String
strSql = "SELECT TOP 10 * FROM Customers" objConn = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim sdaCust As New SqlDataAdapter(strSql, objConn) Dim dstCust As New DataSet()
sdaCust.Fill(dstCust, "Customers") ’Save data to xml file and schema file dstCust.WriteXML(Server.MapPath("Customers.xml"),XmlWriteMode.IgnoreSchema) dstCust.WriteXMLSchema(Server.MapPath("Customers.xsd")) End Sub
这种方法是写入一个xml文件
方法二： <WebMethod(Description:="所有教室列表")> _ Public Function ListAllRooms() As XmlDocument
Try m_CpCourseArrange.FillRoomId(m_DsCourseArrange) ’Dim reader As New MemoryStream
Dim doc As New XmlDocument doc.LoadXml(m_DsCourseArrange.GetXml.ToString) Return doc
Catch ex As Protocols.SoapException Throw SoapExceptionE.RaiseException("ListAllRooms", "http://tempuri.org/CourseArrange", ex.Message, "4000", ex.Source, SoapExceptionE.FaultCode.Server) End Try End Function
GetXML--Returns the XML representation of the data stored in the DataSet. (MSDN)
Private Shared Sub DemonstrateGetXml() ’ Create a DataSet with one table containing two columns and 10 rows. Dim ds As DataSet = New DataSet("myDataSet") Dim t As DataTable = ds.Tables.Add("Items") t.Columns.Add("id", Type.GetType("System.Int32")) t.Columns.Add("Item", Type.GetType("System.String"))
’ Add ten rows. Dim r As DataRow Dim i As Integer For i = 0 To 9 r = t.NewRow() r("id") = i r("Item")= "Item" & i t.Rows.Add(r) Next
’ Display the DataSet contents as XML. Console.WriteLine( ds.GetXml() )End Sub
看来以后用dataset传递的时候也不用为他的转换发愁了。
