Question

在这里，我尝试将用户ID密码与数据库匹配。
if部分运行正常，而else在浏览器中运行。
代码如下：

SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ITD_ClientConnectionString"].ConnectionString);
connection.Open();
string checku = "select count(*) from UserRG where Pan = '" + txtid.Text + "' AND Pass='"+txtpasslog.Text+"' ";

SqlCommand cdm = new SqlCommand(checku, connection);
int temp = Convert.ToInt32(cdm.ExecuteScalar().ToString());
if (temp == 1)
{
    Response.Write("<script>alert('hurry ! welcome user')</script>");
}
else { Response.Write("<script>alert('password doesn't match')</script>"); }

Answer 1

问题必须来自'password doesn't match'

您应该尝试

'password doesn\'t match'或更可能"password doesn't match"

或找到一种方法来摆脱中间的'

C＃，如果条件正常工作，但其他不工作？
