最近用asp.net连接sql server数据库,一直出现相同的问题.很郁闷,特来请教各位
代码如下:
<% @ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<script runat="server">
void Page_Load(Object sender, EventArgs e) {
SqlConnection Conn;
Conn=new SqlConnection("server=localhost;database=pubs;Trusted_Connection=SSPI");
Conn.Open();
Message.Text=Conn.State.ToString();
Conn.Close();
}
</script>
<asp:label id="Message" runat="server" />
注:我的sql server 数据库用的是windows验证.
浏览时提示的错误是:

SQL Server does not exist or access denied.

我把sql server卸了,又装了一遍 这次用的是混合模式登陆(密码为空),还是那样的错误(

SQL Server does not exist or access denied.

).
附:<% @ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<script runat="server">
void Page_Load(Object sender, EventArgs e){
SqlConnection Conn;
Conn=new SqlConnection("server=localhost;database=pubs;uid=sa;pwd=''");
Conn.Open();
Message.Text=Conn.State.ToString();
Conn.Close();
}
</script>
<asp:Label id="Message" runat="server" />

我也有一个类似的问题<%@ Import NameSpace="System.Data" %> <%@ Import NameSpace="System.Data.OleDb" %><% Response.Expires=0 %>

程序代码：

<SCRIPT language=VB Runat=\"Server\">

dim DSN as String
dim tsql as String = \"select *From UserDatas\"
sub page_Load (obj as object, e as EventArgs)
DSN=\"Provider=Microsoft.JET.OLEDB.4.0;Data Source = \" & _
Server.MapPath(\"/ASP/ASP.mdb\") & \";\"
ShowResultSet(DSN,tsql)
end sub
sub button1_click(obj as object, e as eventargs)
dim lret as boolean=false
tsql=\"insert into UserDatas(UserAaccount,UserPWD.UserName,EMail)\"
tsql=tsql &\"values (' \"& request.form(\"UserAccount\")&\" ',\"
tsql=tsql & \" ' \" & request.form(\"Userpwd\") & \" ',\"
tsql=tsql & \" ' \" & request.form(\"UserName\") & \" ',\"
tsql=tsql & \" ' \" & request.form(\"EMail\") & \" ') \"
dim Counts as integer
Counts=opCommand(DSN,tsql)
if Counts >0 then
response.redirect(\"ddd.aspx\")
else
Show1.InnerHtml=\"数据操作命令执行失败!\"
endif
END DUB
