本文介绍了一种使用C#通过注册表保存和读取打印机边距设置的方法。具体包括创建和打开注册表键、设置边距值以及从注册表读取这些值来应用到打印报告中。

其中mRegistryRootKey 为软件的注册表位置

// 函数1 用于设置并将设置结果保存到注册表中例子中只保存了上下左右，如果你有更多需要保存的自己扩展
            PageSetupDialog psDlg = new PageSetupDialog();
            PrinterSettings ps = new PrinterSettings();
            psDlg.PageSettings = ps.DefaultPageSettings;
            RegistryKey regPrint = Registry.LocalMachine.OpenSubKey(mRegistryRootKey + "PrintSetup\\", true);
            if (regPrint != null)
            {
                Margins ms = new Margins();
                ms.Left = Convert.ToInt32(regPrint.GetValue("Left", 100));
                ms.Top = Convert.ToInt32(regPrint.GetValue("Top", 100));
                ms.Right = Convert.ToInt32(regPrint.GetValue("Right", 100));
                ms.Bottom = Convert.ToInt32(regPrint.GetValue("Bottom", 100));
                if (System.Globalization.RegionInfo.CurrentRegion.IsMetric)
                   ms = PrinterUnitConvert.Convert(ms, PrinterUnit.Display, PrinterUnit.TenthsOfAMillimeter);
                psDlg.PageSettings.Margins = ms;
            }
            else
            {
                regPrint = Registry.LocalMachine.CreateSubKey(mRegistryRootKey + "PrintSetup\\");
            }
            if (psDlg.ShowDialog() == DialogResult.OK)
            {
                regPrint.SetValue("Left", psDlg.PageSettings.Margins.Left, RegistryValueKind.String);
                regPrint.SetValue("Top", psDlg.PageSettings.Margins.Top, RegistryValueKind.String);
                regPrint.SetValue("Right", psDlg.PageSettings.Margins.Right, RegistryValueKind.String);
                regPrint.SetValue("Bottom", psDlg.PageSettings.Margins.Bottom, RegistryValueKind.String);
            }
            psDlg.Dispose();

开始使用了例子中是给XtraReport用
        private void fnSetPrintCustom(XtraReport report)
        {
            RegistryKey regPrint = Registry.LocalMachine.OpenSubKeymRegistryRootKey +"PrintSetup\\", false);
            if (regPrint != null)
            {
                int esLeft = Convert.ToInt32(regPrint.GetValue("Left", "-9999"));
                int esTop = Convert.ToInt32(regPrint.GetValue("Top", "-9999"));
                int esRight = Convert.ToInt32(regPrint.GetValue("Right", "-9999"));
                int esBottom = Convert.ToInt32(regPrint.GetValue("Bottom", "-9999"));
                if (esLeft != -99999) report.PrintingSystem.PageSettings.LeftMargin = esLeft;
                if (esTop != -99999) report.PrintingSystem.PageSettings.TopMargin = esTop;
                if (esRight != -99999) report.PrintingSystem.PageSettings.RightMargin = esRight;
                if (esBottom != -99999) report.PrintingSystem.PageSettings.BottomMargin = esBottom;
            }
        }

其实很简单
