文件夹浏览器对话框组件在windows窗体中不显示文件夹列表

本文关键字:文件夹 显示 显示文件 列表 windows 浏览器 对话框 组件 窗体 | 更新日期: 2023-09-27 18:19:29

我有一个包含表单的C#库,我在其中使用文件夹浏览器对话框组件来获取文件夹路径。使用自定义安装程序安装我的应用程序时会显示窗体。单击浏览按钮时显示文件夹浏览器对话框。对话框已打开,但没有文件夹列表,空白对话框显示"确定"answers"取消"按钮。我正在使用以下代码:

FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
folderBrowserDialog.RootFolder = Environment.SpecialFolder.MyComputer;
if (folderBrowserDialog.ShowDialog() == DialogResult.OK)
{
    txtDBPath.Text = folderBrowserDialog.SelectedPath; 
    btnSelectFile.Enabled = true;
}

我该如何解决这个问题。感谢
