< asp：Button ID =Button2Text =<<<< runat =server/>

< asp：按钮ID =Button3Text =<<< runat =server/>

< ajaxToolkit：SlideShowExtender ID =SlideShowExtender1runat =server

TargetControlID =Image1

SlideShowServicePath =〜/ Service.asmx

PreviousButtonID =Button1

PlayButtonID =Button2

NextButtonID =Button3

PlayButtonText =Play

StopButtonText =停止

AutoPlay =true>

解决方案

我假设您收到错误：

  public   static  AjaxControlToolkit.Slide [] GetSlides（）

如果是这样，那么检查您是否拥有适用于AjaxControlToolkit的使用语句，或者包含正确的程序集引用

Web Service file

[System.Web.Script.Services.ScriptService]
[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
public static AjaxControlToolkit.Slide[] GetSlides()
{
AjaxControlToolkit.Slide[] slides=new AjaxControlToolkit.Slide[3];
slides[0]=new AjaxControlToolkit.Slide("12.jpg", "Image1", "a");
slides[1]=new AjaxControlToolkit.Slide("37.jpg", "Image1", "a");
slides[2]=new AjaxControlToolkit.Slide("38l.jpg", "Image1", "a");
return (slides);
}

C# code

<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">

<asp:Image ID="Image1" runat="server" />

<asp:Button ID="Button1" Text="<<<" runat="server" />
<asp:Button ID="Button2" Text="<<<" runat="server" />
<asp:Button ID="Button3" Text="<<<" runat="server" />

<ajaxToolkit:SlideShowExtender ID="SlideShowExtender1" runat="server"
TargetControlID="Image1"
SlideShowServiceMethod="GetSlides"
SlideShowServicePath="~/Service.asmx"
PreviousButtonID="Button1"
PlayButtonID="Button2"
NextButtonID="Button3"
PlayButtonText="Play"
StopButtonText="Stop"
AutoPlay="true">

解决方案

I assume you are getting the error on the line:

public static AjaxControlToolkit.Slide[] GetSlides()

If so, then check that you have the right using statement for the AjaxControlToolkit, or that the right assembly reference is included.
