推荐答案

您将需要OpenFileDialog 让用户浏览文件.

在此处查找用法: http://msdn.microsoft.com/zh-CN /library/system.windows.forms.openfiledialog.aspx [ ^ ]

要保存此文件，您可能需要File 类的静态函数(如File.Copy)将其保存到目录中.

在这两者之间，您可以提取文件名并将其推送到数据库中以进行记录保存.

You will be needing OpenFileDialog to let the user browse the file.

Find the usage here: http://msdn.microsoft.com/en-us/library/system.windows.forms.openfiledialog.aspx[^]

And to save this file you will perhaps be needing the static functions of File class like File.Copy to save them to your directory.

In between you can extract out the file names and push them in the DB for record keeping.

我希望这会有所帮助

I hope this helps

using (OpenFileDialog dlg = new OpenFileDialog())
                {

                    dlg.Filter = "JPG Files (*.jpg)|*.jpg|JPEG Files (*.jpeg)|*.jpeg|bmp Files (*.bmp)|*.bmp|PNG Files (*.png)|*.png|GIF Files (*.gif)|*.gif";
                    if (dlg.ShowDialog() == DialogResult.OK)
                    {
                        FileInfo file = new FileInfo(dlg.FileName);

                        if (file.Length == 0)
                        {
                            MessageBox.Show("Invalid image. Please select valid image.", Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Information);
                            return;
                        }
                        else if (file.Length > 2097152)
                        {
                            MessageBox.Show("Image size cannot exceed 2MB.", Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Information);
                            return;
                        }
                        //SAVE YOUR FILE HERE. IN  THIS CASE IT WILL BE IMAGE

                    }

                }
