                SqlParameter param = new SqlParameter("@bookname", bookname);
                cmd.Parameters.Add(param);

                con.Open();

                while (rdr.Read())
                {
                    booknames.Add(rdr["Name"].ToString());
                }
                return booknames;
            }
        }
    }
}

它显示

中的错误

Line 1:  <%@ WebService Language="C#" CodeBehind="WebService1.asmx.cs" Class="LibraryProgram.WebService1" %>

但是我无法找到这条线。我可以在哪里找到这条线。请帮助我。我已经看到了这个错误。有人发布了更改代码文件而不是codebehind.but我无法在代码中找到该行。谢谢

您可能已将默认服务名称从Service1更改为Service2。请右键单击.asmx文件并选择“查看标记”进行检查，它会显示标记为： -

<%@ WebService Language="C#" CodeBehind="Service.asmx.cs" Class="Service.Service1" %>

将其更改为： -

<%@ WebService Language="C#" CodeBehind="Service.asmx.cs" Class="Service.Service2" %>

请注意我使用了虚拟命名空间＆amp;这里的服务名称，实际名称必须不同。

错误是什么意思“'/'应用程序中的服务器错误。”
