What I have tried:

string[] files = Directory.GetFiles(@"C:\PrintingDocument\");
                
                foreach (string file in files)
                {
                    //if (string.IsNullOrEmpty(file))
                    //{
                    //    //txtFileName.BackColor = Color.Yellow;
                    //    //MessageBox.Show("Please Select file.");
                    //    return;
                    //}
                    if (File.Exists(file))
                    {
                        ProcessStartInfo info = new ProcessStartInfo(file);
                        info.Verb = "Print";
                        info.CreateNoWindow = true;
                        //info.UseShellExecute = false;
                        info.WindowStyle = ProcessWindowStyle.Hidden;
                        Process.Start(info);
                        
                        //TraceService(@"C:\PrintingDocument\" + file);
                        //TraceService(@"C:\PrintedDocument\" + file);
                        System.IO.File.Move(@"C:\PrintingDocument\" + file, @"C:\PrintedDocument\" + file);
                        TraceService("Printed Successfully" + " " + DateTime.Now.ToString());
                        
                    }
                    else
                    {
                        TraceService("Not File found" + " " + DateTime.Now.ToString());
                    }

                }

推荐答案

参见Directory.GetFiles Method（System.IO） [ ^ ]：

See Directory.GetFiles Method (System.IO)[^]:

Quote：

返回指定目录中文件的名称（包括它们的路径）。

Returns the names of files (including their paths) in the specified directory.

您的文件变量不是单个文件名，而是完整路径。您必须从中提取文件名（请参阅路径.GetFileName方法（字符串）（System.IO） [ ^ ]）。





示例：

Your file variable is not a single file name but a complete path. You must extract the file name from it (see Path.GetFileName Method (String) (System.IO)[^] ).


Example:

string fileName = Path.GetFileName(file);
System.IO.File.Move(file, @"C:\PrintedDocument\" + fileName);
