c# - 如何在选定的打印机中打印任何文档

Question

我想使用 .net 在选定的打印机中打印任何文档，例如 pdf、word、excel 或文本文件。我已经成功在默认打印机中进行此类打印。现在唯一的问题是在选择的打印机。

这是打印代码。

public bool Print(string FilePath)
    {
        if (File.Exists(FilePath)) {
            if (ShellExecute((System.IntPtr )1, "Print", FilePath, "", Directory.GetDirectoryRoot(FilePath), SW_SHOWNORMAL).ToInt32() <= 32) {
                return false;
            } else {
                return true;
            }
        } else {
            return false;
        }
    }

Process printJob = new Process();
printJob.StartInfo.FileName = path;
printJob.StartInfo.UseShellExecute = true;
printJob.StartInfo.Verb = "printto";
printJob.StartInfo.CreateNoWindow = true;
printJob.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
printJob.StartInfo.Arguments = "\"" + printerAddress + "\"" + " " + printerExtraParameters;
printJob.StartInfo.WorkingDirectory = Path.GetDirectoryName(path);
printJob.Start();
