推荐答案

试试下面的代码

    private void Button1_Click(object sender, EventArgs e)
    {
        CrystalReport1 report1 = new CrystalReport1();
        PrintDialog dialog1 = new PrintDialog();

        report1.SetDatabaseLogon("username", "password");

        dialog1.AllowSomePages = true;
        dialog1.AllowPrintToFile = false;

        if (dialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            int copies = dialog1.PrinterSettings.Copies;
            int fromPage = dialog1.PrinterSettings.FromPage;
            int toPage = dialog1.PrinterSettings.ToPage;
            bool collate = dialog1.PrinterSettings.Collate;

            report1.PrintOptions.PrinterName = dialog1.PrinterSettings.PrinterName;
            report1.PrintToPrinter(copies, collate, fromPage, toPage);            
        }

        report1.Dispose();
        dialog1.Dispose();
    }

您必须使用数据库的凭据更改用户名"和密码".

you will have to change the "username" and the "password" with the credentials of your database.
