LastSelectedFolder不存在。 我试图将项目属性转到“设置”选项卡,然后我将值添加到LastSelectedFolder。
所以现在我有:名称设置类型字符串范围用户值LastSelectedFolder
但它仍然无法正常运行错误,并且在保存单击btnStart时将其加载到何处以及如何加载后仍然无效?
默认后,即使将LastSelectedFolder添加到“设置”后,LastSelectedFolder也不存在:

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。因此,您还可以使用FolderBrowserDialog.SelectedPath
属性。这是您的代码,附加行:
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();
}
}
在屏幕截图中,您将设置命名为Setting
。将此值更改为LastSelectedFolder
并清除默认值(最后一列)。
之后你可以编译并运行!

试试这个:
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();
}
