推荐答案

首先，您需要确保使用正确的密码.
然后确保与数据库的连接正常工作.

First of all, you need to make sure you are using the right password.
Then ensure the connection to the database is working properly.

要使此操作容易，请首先使用静态密码和用户ID.读取文本框的值并使用条件进行检查:

to make this easy first use static password and user id. read the value of textbox and check using condition :

if(txtUserName.Text=="Abc" && txtPassword.Text=="Abc123")
{
Response.Write("welcome Login"); // code here
}
else
{
//....
}

如果正确，则检查数据库连接.使用调试检查要传递给数据库并正在执行的查询.并在try catch块中查找wrie代码，并在出现异常时打印出异常，由此您可以轻松找到问题所在.

if it is correct then check your database connection. Using debug check the query that you are passing to database and executing. and wrie code in try catch block and print the exception if there is, from this you can easily find where is the problem.

try
{
//code here...

}
catch(Exception ex)
{
Response.Write(ex.Message);
}
