以下代码是在VB.NET（Framework 2.0）中调用SQLServer2005 的Intergration Service中DTS包。
1 如果要在WebService中调用DTS,必须用VB.NET语言。因为如果用C#编写WebService的话，将无法引用Microsoft.SqlServer.ManagedDTS组件。
2 将NETWORK SERVICE帐户添加到Administrator组中，否则将不能执行DTS。（会带来安全漏洞）
1 Imports Microsoft.SqlServer.Dts.Runtime

3 'WebService代码
4 <WebMethod()> _
5 Public Function ExecutePackage() As Integer
6 Dim pkg As String = "D:\Development\Programe\PackageDev\Package\MG-TSJF-PKG.dtsx"

8 Dim app As Application = New Application()
9 Dim p As Package = app.LoadPackage(pkg, Nothing)
10 'p.InteractiveMode = True

12 Dim vir As Variables = p.Variables
13 vir("用户::PackageID").Value = 4

15 If p.Execute(Nothing, vir, Nothing, Nothing, Nothing) = DTSExecResult.Success Then
16 Return 0
17 Else
18 Return 1
19 End If
20 End Function
