1、winform 点击按钮选择文件保存的路径，效果如下图：

具体代码如下：

private void button8_Click(object sender, EventArgs e)
{
FolderBrowserDialog dialog = new FolderBrowserDialog();
dialog.Description = "请选择文件路径"; if (dialog.ShowDialog() == DialogResult.OK)
{
string foldPath = dialog.SelectedPath;
DirectoryInfo theFolder = new DirectoryInfo(foldPath); //theFolder 包含文件路径 FileInfo[] dirInfo = theFolder.GetFiles();
//遍历文件夹
foreach (FileInfo file in dirInfo)
{
MessageBox.Show(file.ToString());
}
}
}

winform 打开指定的文件夹

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

2、winform 打开指定文件，精确到文件

OpenFileDialog dialog = new OpenFileDialog();
dialog.Multiselect = true;//该值确定是否可以选择多个文件
dialog.Title = "请选择文件夹";
dialog.Filter = "所有文件(*.*)|*.*";
if (dialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string file = dialog.FileName;
}
