大家知道，用dataset傳遞的WebService，微軟會(huì)在各個(gè)節(jié)點(diǎn)加上schema,所以無法與j2ee，flash兼容，所以我找到了一種轉(zhuǎn)換他們變成普通xml的方法。代碼如下： 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 這種方法是寫入一個(gè)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
看來以后用dataset傳遞的時(shí)候也不用為它的轉(zhuǎn)換發(fā)愁了。
