如何从互联网下载多个字符串并检查一个字符串是否为真

首先，这不是对用户进行身份验证的好方法。但假设你只是为了学习：

WebClient.DownLoadString（） 将页面内容作为一个完整的字符串获取。您必须拆分字符串。像这样的东西将适用于您的条件：

        bool authenticated = false;
        WebClient client = new WebClient();
        string userinfoLines = client.DownloadString("http://pastebin.com/raw.php?i=LAUx2zxn");
        foreach (string userinfo in userinfoLines.Split(new[] {Environment.NewLine},StringSplitOptions.RemoveEmptyEntries))
        {
        if (userinfo == username.Text + ":" + password.Text)
        {
            authenticated = true;
            MessageBox.Show("Successfully logged in as " + username.Text + ".", Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
            label1.Text = "Welcome, " + username.Text;
            label1.Visible = true;
            this.Hide();
            MainMenu ss = new MainMenu();
            ss.Show();
            break;
        }
        }
        if (!authenticated)
        {
            // Login failed, I added my own stuff here.
            MessageBox.Show("Invalid account info entered.'n If you want to buy an account msg'n YouRGenetics 'nOn Skype'n Or Click On Buy Account", Text, MessageBoxButtons.OK, MessageBoxIcon.Error);
        }

试试这个。

var client = new WebClient();
var source = client.DownloadString("http://pastebin.com/raw.php?i=LAUx2zxn");
var data = new List<string>(source.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries));
if (data.ConvertAll(d => d.ToLower()).Contains(string.Concat("user", ":", "pass")))
{
     // Successfully logged in.
}
else
{
     // Invalid credentials
}
