C# winform 選擇文件保存路徑

1、winform 點擊按鈕選擇文件保存的路徑，效果如下圖：

 

具體代碼如下：

     private void button8_Click(object sender, EventArgs e)
        {
            FolderBrowserDialog dialog = new FolderBrowserDialog();
            dialog.Description = "請選擇文件路徑";

            if (dialog.ShowDialog() == DialogResult.OK)
            {
                string foldPath = dialog.SelectedPath;
                DirectoryInfo theFolder = new DirectoryInfo(foldPath);
                
                //theFolder 包含文件路徑

                FileInfo[] dirInfo = theFolder.GetFiles();
                //遍歷文件夾                
                foreach (FileInfo file in dirInfo)
                {
                    MessageBox.Show(file.ToString());
                }
            }
        }

 

winform 打開指定的文件夾

 System.Diagnostics.Process.Start("路徑");

 

2、winform 打開指定文件，精確到文件

OpenFileDialog dialog = new OpenFileDialog();
dialog.Multiselect = true;//該值確定是否可以選擇多個文件
dialog.Title = "請選擇文件夾";
dialog.Filter = "所有文件(*.*)|*.*";
if (dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    string file = dialog.FileName;
}
