How to check and change labels and textboxes in ASP.net-CodePudding

I am trying to make a website using asp.net. First you must log in. This textbox is called "Username" and there is a textbox called "Password".

If Username = Hello and Password = 123 then I want the page to redirect. If it doesn't match then I want a pre-existing label called "ErrorMessage" to display a message saying "Please check Username and password".

Here is my current code in the button click event. Nothing works so far.

If (Username.Text.Contains("Hello")) & (Password.Text.Contains("123")) Then
            Response.Redirect("MemberContactInfo.aspx")
        Else
            ErrorMessage.Text = "Please check username and password"
        End If

CodePudding user response：

You're using the wrong operator in your If statement. When you want two conditions to be true, you should use the And operator, not the & operator (which performs string concatenation).

Modify your code as follows:

If (Username.Text.Contains("Hello")) And (Password.Text.Contains("123")) Then
    Response.Redirect("MemberContactInfo.aspx")
Else
    ErrorMessage.Text = "Please check username and password"
End If
