[英]How can I save and load the last selected folder by user with FolderBrowserDialog?
private void btnStart_Click(object sender, EventArgs e)
{
System.Windows.Forms.FolderBrowserDialog openFolderDialog = new System.Windows.Forms.FolderBrowserDialog();
if (openFolderDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Properties.Settings.Default.LastSelectedFolder = openFolderDialog.SelectedPath.ToString();
Properties.Settings.Default.Save();
}
The LastSelectedFolder not exist. LastSelectedFolder不存在。 I tried to go to the project properties to the Settings tab and there i added to the value the LastSelectedFolder.
我尝试转到项目属性的“设置”选项卡,然后在其中添加了LastSelectedFolder值。
So now I have: Name Setting Type string Scope user Value LastSelectedFolder 所以现在我有了:名称设置类型字符串范围用户值LastSelectedFolder
But it's not working still getting the error and also after saving where and how do I load it back when clicking the btnStart? 但是它仍然无法正常工作,并且仍然出现错误,并且在保存位置以及单击btnStart时如何将其重新加载?
The LastSelectedFolder is not exist after the Default even after added it to the Settings: 即使将默认值添加到“设置”中,LastSelectedFolder也不会存在:
You have to set the last path as default if you create a new dialog. 如果创建新对话框,则必须将最后一个路径设置为默认路径。 Therefore you can use also the
FolderBrowserDialog.SelectedPath
property. 因此,您也可以使用
FolderBrowserDialog.SelectedPath
属性。 Here is your code with the additional line: 这是带有附加行的代码:
private void btnStart_Click(object sender, EventArgs e)
{
System.Windows.Forms.FolderBrowserDialog openFolderDialog = new System.Windows.Forms.FolderBrowserDialog();
openFolderDialog.SelectedPath = Properties.Settings.Default.LastSelectedFolder;
if (openFolderDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Properties.Settings.Default.LastSelectedFolder = openFolderDialog.SelectedPath.ToString();
Properties.Settings.Default.Save();
}
}
In your screenshot you named your setting Setting
. 在屏幕快照中,您将
Setting
命名为Setting
。 Change this one to LastSelectedFolder
and clear the default value (last column). 将此更改为
LastSelectedFolder
并清除默认值(最后一列)。
After that you can compile and run! 之后,您可以编译并运行!
Try this: 尝试这个:
private void btnStart_Click(object sender, EventArgs e)
{
System.Windows.Forms.FolderBrowserDialog openFolderDialog = new System.Windows.Forms.FolderBrowserDialog();
openFolderDialog.SelectedPath = Properties.Settings.Default.LastSelectedFolder;
if (openFolderDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Properties.Settings.Default.LastSelectedFolder = openFolderDialog.SelectedPath.ToString();
Properties.Settings.Default.Save();
}
