report service 中的[Property]应该如何引用？

[ydm_wuk123]

以下是微软的示例代码：

Imports System
Imports System.Web.Services.Protocols

Class Sample
Public Shared Sub Main()
Dim rs As New ReportingService()
rs.Credentials = System.Net.CredentialCache.DefaultCredentials

Dim props(0) As [Property]
Dim setProp As New [Property]()
setProp.Name = "Description"
setProp.Value = "Sales by quarter and product category."
props(0) = setProp

Dim itemPath As String = "/SampleReports/Company Sales"

Try
rs.SetProperties(itemPath, props)
Console.WriteLine("New description set on item {0}.", itemPath)

Catch ex As SoapException
Console.WriteLine(ex.Detail.OuterXml)
End Try
End Sub 'Main
End Class 'Sample

可是放到asp.net 中老是说类型不正确．应该如何做，急．．．．．．
