解决方案
解决方案二：
logon.aspx________________<%PageLanguage="C#"AutoEventWireup="true"CodeFile="Logon.aspx.cs"Inherits="Logon"%><!DOCTYPEhtmlPUBLIC"-//W3C//DTDXHTML1.0Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><htmlxmlns="http://www.w3.org/1999/xhtml"><headrunat="server"><title>Login.axp</title></head><body><formid="form1"runat="server"><tableheight="100%"cellSpacing="0"cellpadding="0"width="100%"border="0"><tr><tdheight="52"align="center"><asp:LoginID="Login1"runat="server"BackColor="#F7F7DE"BorderColor="#CCCC99"BorderStyle="solid"BorderWidth="1px"Font-Names="Verdana"Font-Size="10px"OnAuthenticate="OnAuthenticate"/><TitleTextStyleBackColor="#6B696B"Font-Bold="True"ForeColor="#FFFFFF"/></asp:Login><br/><ahref="CreateUser.aspx">newuserregister</a></td></tr></form></body></html>少了个/
解决方案三：
publicpartialclassLogon===============这里换一个类名,比如LoginFormpublicpartialclassLoginForm别忘了aspx也要修改<%@PageLanguage="C#"AutoEventWireup="true"CodeFile="Login.aspx.cs"Inherits="LoginForm"%>你的类名和ASP.NET提供的控件名冲突了
解决方案四：
Microsoft.NETFrameworkVersion:1.1.4322.2407;ASP.NETVersion:1.1.4322.2407===貌似用的.NET1.1,那应该不是我刚才提到的问题,sorry
