解决方案
解决方案二：
TextValidateTextValidate2是什么?
解决方案三：
你的SqlCommand可以写在CONN的上面啊if(TextValidate.Text.Trim()==TextValidate2.Text.Trim())你改成if(read.Hasrows)
解决方案四：
而且循环都乱写
解决方案五：
protectedvoidlogoButt1_Click(objectsender,EventArgse){SqlConnectionsqlconn=newSqlConnection(ConfigurationManager.AppSettings["DBConnectionString"]);SqlCommandsqlcom=newSqlCommand("proAdminInfo",sqlconn);sqlcom.CommandType=CommandType.StoredProcedure;sqlcom.Parameters.Add("@AdminName",SqlDbType.Char,20).Value=TextName.Text.Trim();sqlcom.Parameters.Add("@AdminPwd",SqlDbType.Char,20).Value=TextPasswd.Text.Trim();sqlconn.Open();SqlDataReaderread=sqlcom.ExecuteReader();if(read.Hasrows){while(read.Read()){Response.Write("<scriptlanguage=javascript>window.open('Welcom.aspx');window.close();</script>");}else{Response.Write("<script>alert('您输入的用户名或密码错误，请重新输入！');location='javascript:history.go<-l>';</script>");}}elseResponse.Write("<script>alert('验证码输入有误，请重新输入！');location='javascript:history.go<-l>';</script>");}
解决方案六：
验证图片我用textbox代替了TextValidateTextValidate2分别是输入验证码的和显示验证码的，问题解决了，谢谢大家！刚接触.net还有很多问题，希望大家多帮助！
