c# - 错误 : DropdownList server error

Question

我有这个下拉列表:

<asp:DropDownList runat="server" ID="CatsList" AutoPostBack="True" AppendDataBoundItems="True" DataSourceID="CatsDataSource" DataTextField="CatName" DataValueField="CatId" ClientIDMode="Static" OnSelectedIndexChanged="CatsList_SelectedIndexChanged" OnDataBound="CatsList_DataBound">
    <asp:ListItem Value="1">* SELECT CATEGORY *</asp:ListItem>
</asp:DropDownList>

这在我的本地机器上运行完美，但是当我将它上传到服务器时出现了这个错误:

Server Error in '/' Application.

Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'ASP.categorybrands_aspx' does not contain a definition for 'CatsList_SelectedIndexChanged' and no extension method 'CatsList_SelectedIndexChanged' accepting a first argument of type 'ASP.categorybrands_aspx' could be found (are you missing a using directive or an assembly reference?)

Source Error:

Line 24:                 <div class="service span3" style="background-color:#fff;border:none;margin-bottom:0px;padding-bottom:0px;">                                      
Line 25:                     <h4 style="color:#ff6a00;font-family:Corbel;">Category</h4>
Line 26:                     <asp:DropDownList runat="server" ID="CatsList" AutoPostBack="True" AppendDataBoundItems="True" DataSourceID="CatsDataSource" DataTextField="CatName" DataValueField="CatId" ClientIDMode="Static" OnSelectedIndexChanged="CatsList_SelectedIndexChanged" OnDataBound="CatsList_DataBound">
Line 27:                         <asp:ListItem Value="1">* SELECT CATEGORY *</asp:ListItem>
Line 28:                     </asp:DropDownList>

我的 .cs 文件中有 CatsList_SelectedIndexChanged 方法，我真的不明白这个错误!

好吧，这是一个愚蠢的错误，但我想出了一个简单的解决方案!!

1. 我清理了我的解决方案。
2. 再次重建
3. 重新上传应用。到服务器。

它现在正在工作。
