Question

我正在尝试使用ajax自动完整扩展程序，但它无法正常工作.... 我在Web服务中的GetCompanyNames方法上设置了一个断点，但它甚至没有达到断点。

这是我的ajax autoextender

<asp:TextBox TabIndex="1" ToolTip="* Required - enter the Company name" ID="txtCompanyName"
runat="server"></asp:TextBox>
<ajaxToolkit:AutoCompleteExtender runat="server" ID="acCompanyName" TargetControlID="txtCompanyName" ServiceMethod="GetCompanyNames" ServicePath="~/WebServices/AutoComplete.asmx" MinimumPrefixLength="1" 
EnableCaching="true">
 </ajaxToolkit:AutoCompleteExtender>

这是我创建的网络服务

    Imports System.Web
    Imports System.Web.Services
    Imports System.Web.Services.Protocols

    ' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the    following line.
    ' <System.Web.Script.Services.ScriptService()> _
    <WebService(Namespace:="http://tempuri.org/")> _
    <WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
    <System.Web.Script.Services.ScriptService()> _ 
    Public Class AutoComplete
        Inherits System.Web.Services.WebService

<WebMethod()> _
Public Function HelloWorld() As String
    Return "Hello World"
End Function

<WebMethod()> _
Public Function GetCompanyNames(ByVal prefixTest As String) As String()

    Dim db As New DataClassesDataContext

    Dim company = From c In db.CT_Companies
                  Where c.CompanyName.Contains(prefixTest)
                  Select c.CompanyName

    Return company.ToArray

End Function

    End Class

有人能看到我做错了什么或错过了吗？感谢

根据文档here，您在方法签名上缺少<System.Web.Script.Services.ScriptMethod()>属性和整数count参数。
